aryaxt / ocmapper Goto Github PK

Hello,

I am using OCMapper in my Xcode 5 project which is under OS X 10.8.5.

I am trying the sample test as following, but the user_id is null, the object didn't get mapped I don't know why?

Here is my Model:

#import <Foundation/Foundation.h>

@interface User : NSObject

@property (nonatomic) int user_id;

@property (nonatomic) NSString* registration;


@end

Here is my Test

#import <XCTest/XCTest.h>
#import "ObjectMapper.h"
#import "InCodeMappingProvider.h"
#import "ObjectInstanceProvider.h"
#import "CommonLoggingProvider.h"
#import "User.h"

@interface TestJson : XCTestCase

@property (nonatomic, strong) ObjectMapper *mapper;
@property (nonatomic, strong) InCodeMappingProvider *mappingProvider;

@end


@implementation TestJson
@synthesize mapper;
@synthesize mappingProvider;

- (void)setUp
{
    [super setUp];

    self.mappingProvider = [[InCodeMappingProvider alloc] init];
    self.mapper = [[ObjectMapper alloc] init];
    self.mapper.mappingProvider = self.mappingProvider;
}

- (void)tearDown
{
    self.mapper = nil;
    self.mappingProvider =  nil;
    [super tearDown];
}


- (void)test1
{

    NSMutableDictionary *dic = [[NSMutableDictionary alloc]init];
    [dic setObject:[NSNumber numberWithInt:10] forKey:@"user_id"];
    [dic setObject:@"Value2" forKey:@"registration"];

    User *user = [self.mapper objectFromSource:dic toInstanceOfClass:[User class]];
    NSLog(@" user.user_id - %@", user.user_id);    // here the user.user_id is null
}

@end

So I have 3 questins:
1, is Xcode 5 + OS X 10.8 supported by the latest OCMapper 2.1 version?

2, I tried to use like this (I saw on StackOverflow)
User *user = [User objectFromDictionary:dic];
but this needs to add
#import "NSObject+ObjectMapper.h"

Is this the right way to use OCMapper, why we need a mapper and mappingProvider?

3, in case the Model has more properties than the dictionary, for exampel, we have only user_id in the dictionary while User has user_id + registration, does OCMapper support the optional mapping?

I've been using OCMapper in Swift and I've run into a compilation problem. This may be an issue with XCode/Swift/Objective-C, but I figured I would open an issue here.

All was working well until I tried to subclass a custom Objective-C class that I had created (a subclass of UIViewController). When I tried to do this, I ran into a build error which pointed to OCMapper.

Not subclassing the custom Objective-C class makes the build error go away (even if I still do the import).

Any ideas?

For some weird reason, converting an object to a dictionary crashed with the following error:

valueForUndefinedKey:]: this class is not key value coding-compliant for the key stringByRemovingPercentEncoding

if there was a string generated with the following code set to a property in the object

func generateRandomKey(amountOfCharacters: Int) -> String {

    var alphabet = Array("abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXZY0123456789".characters)
    var randomKey = String()

    for (var i = 0; i < amountOfCharacters; i++) {
        randomKey.append(alphabet[Int(arc4random_uniform(62))])
    }

    return randomKey
}

I have now changed to the following solution and it works, funny though:

func generateRandomKey (len : Int) -> String {

    let letters : NSString = "abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ0123456789"

    let randomString : NSMutableString = NSMutableString(capacity: len)

    for (var i=0; i < len; i++){
        let length = UInt32 (letters.length)
        let rand = arc4random_uniform(length)
        randomString.appendFormat("%C", letters.characterAtIndex(Int(rand)))
    }

    return randomString as String
}

I was hoping to use this for an OS X / Swift project, but noticed that it only supports iOS. Is this something that you're considering adding? If you could point me in the right direction, maybe I could try getting it to work.

You added automatic conversion from underscores to camelCase in 2.1 (#31), but it doesn't seem to work the other way: converting camelCase to underscores. This way it is not possible to communicate with a server using underscores correctly without creating separate modell classes for incomming and outgoing communication.

Or am I doing something wrong? I am using it from Swift if it matters.

Add feature to be able to convert flat data (from NSDictionary) to Structured Object:

FROM NSDICTIONARY
id
firstName
lastName
street
city
country
zipCode

TO COMPLEX OBJEXT
User
____id
____firsname
____lastname
____address
___________city
___________country
___________zipCode

Is there a way to use OCMapper with watchOS? If not at the moment are there any chances to support watchOS platform any soon?

I'm integrating watch support in my project and already using OCMapper in the iOS app. I thought to pass my objects as json between host app and watch and to automatically serialize/deserialize them but I've stuck integrating OCMapper to watch extension and getting the following error while executing pod install:

Analyzing dependencies
[!] The platform of the target Watch Extension (watchOS 3.1) is not compatible with OCMapper (2.1), which does not support watchos.

the podfile:

target 'Watch Extension' do
pod 'OCMapper'
end

Should I always use "sharedInstance" instead of creating new instance of ObjectMapper?

In this particular situation I need to map an array to a nested object.

From
{p:[3,4]}
To
X
_p
__a
__b

The Jackson Java library supports custom factory methods, e.g., through the @JsonCreator annotation, that allow me to realize such a mapping in the following way. Jackson then searches for a suitable factory method whenever it has to map int[] to P. Support for some sort of factory methods would be a powerful feature.

public class X {
    @JsonProperty("p")
    private P p;
}

public class P {
    private int a;
    private int b;

    public P(int a, int b) {
        this.a= a;
        this.b= b;
    }

    @JsonCreator
    public static P fromValue(int[] array) {
        return new P(array[0], array[1]);
    }
}

I have 2 model classes

@interface PBQuiz : NSObject <OCMapperConfigurable>

@property (nonatomic, strong) NSString* name;
@property (nonatomic, strong) NSString* image;
@property (nonatomic, strong) NSNumber* weight;
@property (nonatomic, strong) NSArray<NSString*>* tags;
@property (nonatomic, strong) NSString* desc;
@property (nonatomic, strong) NSString* descriptionImage;
@property (nonatomic, strong) NSString* quizId;

@end

and

@interface PBQuizDetail : PBQuiz <OCMapperConfigurable>

@property (nonatomic, strong) NSDate* dateStart;
@property (nonatomic, strong) NSDate* dateExpire;
@property (nonatomic, strong) PBQuizType* type;
@property (nonatomic, strong) NSArray<PBQuizGrade*>* quizGrades;
@property (nonatomic, strong) NSNumber* status;
@property (nonatomic, strong) NSNumber* questionOrder;
@property (nonatomic, strong) NSNumber* deleted;
@property (nonatomic, strong) NSNumber* totalMaxScore;
@property (nonatomic, strong) NSNumber* totalQuestions;
@property (nonatomic, strong) NSNumber* questions;
@property (nonatomic, strong) NSNumber* totalScore;
@property (nonatomic, strong) NSDate* dateJoin;

@end

I have to manually add the following code

[mappingProvider mapFromDictionaryKey:@"grades" toPropertyKey:@"grades" forClass:[PBQuizDetail class] withTransformer:^id(id currentNode, id parentNode) {
        return currentNode;
    }];

just to return currentNode in order to receive value from JSON. If I didn't do this, I will always get 0 elements. Interesting thing also is that it's marked as JKArray type when I see it in debugger. I also use JSONKit. I'm not sure if OCMapper is conflict with JSONKit and cause this issue.

Note, OCMapperConfigurable is just protocol I use which has no effect of this issue.

Hi,

When using the following method:

(id)dictionaryFromObject:(NSObject *)object;

and object inherit NSManagedObject, the dictionary returned has a lot of NSManagedObject properties that I'd like to remove (like inserted, deleted, hasChanges, faultingState etc). Is there is an easy way to do that?

Thanks

Hi!

I see there is an Alamofire Request extension example in the README, but if I'm correct it is not for the newest, 3.x version of Alamofire. Can you update it to show how can OCMapper be used with Alamofire 3.x. It would be really appreciated!

I need array on NSDate, like this

@objc public class User: NSObject {
var dates: [NSDate]?
}

And in JSON
{
"dates": [
"11/12/13",
]
}

But providing property does not work.

let propertyProvider = InCodeMappingProvider()
propertyProvider.mapFromDictionaryKey("dates", toPropertyKey: "dates", withObjectType: NSDate.self, forClass: User.self)

ObjectMapper still generates strings.

Should I use provider with transformer or there is other way to do what i want?

Works fine if I add to method

• (id)objectFromSource:(id)source toInstanceOfClass:(Class)class;

condition

else if ([source isKindOfClass:[NSString class]] && class == [NSDate class] ){
return [self dateFromString:source forProperty:nil andClass:NULL];
}

But it looks ugly)

Right now we're using mapFromDictionaryKey() to map a variable to the class type which works fairly well. But, as I remember in Android GSON will automatically detect the type and just parse it using that class.

Just curious - is there a way OCMapper can figure this out itself?

ie: any way OCMapper could figure out that homeTeam variable is of class type GameStatusTeam and not require the mapping below?

    var homeTeam: GameStatusTeam?

...

        mapper().mapFromDictionaryKey("homeTeam", toPropertyKey:"homeTeam", withObjectType:GameStatusTeam.self, forClass:GameStatus.self);

It is quite common for a server to return 0 or 1 for boolean values. It would be great if OCMapper could automatically parse this as booleans. I use it in Swift but I think this is possible to implement both in Swift and Objective-C.

For now, I created a MappingTransformer for this which I have to set for every parameter where I would like to use it:

Swift 2.x:

let intToBoolTransformer: MappingTransformer = {
    currentNode, parentNode in
    return currentNode as? NSNumber == 1 ? true : false
}

Swift 3.x (Somehow casting to Int always results in nil):

let intToBoolTransformer: MappingTransformer = {
    currentNode, parentNode in
    return currentNode as? NSNumber == 1 ? true : false
}

Thanks in advance!

Hi,

I've been using OCMapper for several weeks now and I'm a big fan! While there's a few things I'd love to see improved - in general it was the best JSON <-> Object library I could find for iOS.

However, every once and a while I noticed my app is crashing and the stack trace points inside of OCMapper. It's very difficult to reproduce which makes the crash even worse in my mind.

But, my theory is that OCMapper isn't thread-safe. We have a thread pool handling responses from the server and OCMapper processes everything as a singleton.

Is this a known limitation? I can handle the results in a single thread to be safe as well but wanted to know if it's supposed to be thread-safe and the issue is elsewhere in my code.

@interface ObjectMapper()
@property (nonatomic, strong) NSMutableArray *commonDateFormaters;
@property (nonatomic, strong) NSMutableDictionary *mappedClassNames;
@property (nonatomic, strong) NSMutableDictionary *mappedPropertyNames;
@property (nonatomic, strong) NSMutableArray *instanceProviders;
@end

I have an array of treatments. The class name is ICATreatment. The mapper maps the array to dictionary correctly, but fails to map from dictionary to array.

I often have to interact with APIs that use underscores in their JSON responses (e.g. 'some_property'). This forces me to do a lot of manual mapping to convert to ObjC/Swift camel case properties (e.g. 'someProperty). It would be fantastic if OCMapper could automatically convert between the two.

Hi I'm using OCMapper in swift 1.2 and it is working correctly. But migrating to swift 2.0, it gives nil object.

In My Object

public class Response: NSObject {

    var flag = false
    var message : String?
    var announcement : String?
    var data : User?
}

public class User : Object  {

    dynamic var id = ""
    dynamic var imgName = ""
    dynamic var imageUrl = ""
    dynamic var mobile = ""
    dynamic var firstName = ""
    dynamic var lastName = ""
    dynamic var email = ""
}

User is a Realm Object. When I map object from dictionary

 let response = dictionary?.toClass(Response.self)

or

let user = ObjectMapper.sharedInstance().objectFromSource(dictionary, toInstanceOfClass: Response.self) as? Response

Response gives data = nil and mapping failed.
It is working in Swift 1.2 so any issue of OCMapper with Swift 2.0 or any update for it?

Hi, i have a JSON like this

{
  "total_item": 250,
  "item_per_page": 50,
  "current_page": 1,
  "total_page": 5,
  "data": [
    {
      "data": {
        "id": 1,
        "name": "Happy New Year 2016",
        "logo": {
          "ratio": 1,
          "path_1x": "https://3.bp.blogspot.com/-KUivQF0u7ME/VoMhw9LmM4I/AAAAAAAAASM/wt4gB6bT-Mk/s640/happy-new-year-2016-wishes.jpg",
          "path_2x": "https://3.bp.blogspot.com/-KUivQF0u7ME/VoMhw9LmM4I/AAAAAAAAASM/wt4gB6bT-Mk/s640/happy-new-year-2016-wishes.jpg"
        },
        "main_category": {
          "id": 0,
          "name": "Mall"
        }
      },
      "type": 2
    },

Inside "data" got another "data". My model class is

    var totalPage: NSNumber!
    var totalItem: NSNumber!
    var currentPage: NSNumber!
    var itemPerPage: NSNumber!
    var data: [T]!

What i going to do is i need to get the data.data from JSON and map to data.
So i write a code

class func createFromJSON<T>(type: T, dictionary:Dictionary<String, AnyObject>, provider: InCodeMappingProvider) -> PaginateListModel<T>
    {
        var model = PaginateListModel<T>()
        model = ObjectMapper.sharedInstance().objectFromSource(dictionary, toInstanceOfClass: PaginateListModel<T>.self) as! PaginateListModel<T>

        let dictData = dictionary["data"] as! [Dictionary<String, AnyObject>]
        provider.mapFromDictionaryKey("data.data", toPropertyKey: "data", withObjectType:  T.self , forClass: PaginateListModel<T>.self)
        ObjectMapper.sharedInstance().mappingProvider = provider
        model.data = ObjectMapper.sharedInstance().objectFromSource(dictData, toInstanceOfClass: T.self) as! [T]


        return model
    }

But i can't get the result. Please help. Thank you.

Hello!
Maybe its bug, i wanna report it.

So, we have Class:

@interface TFResponse : NSObject
@property(nonatomic, assign) BOOL status;
@property(nonatomic, weak) NSDictionary *data;
@end

And DICT:

{
    data =     {
        code = 0;
        message = "test message";
    };
    status = 0;
}

After use code:

TFResponse *response = [TFResponse objectFromDictionary:responseObject];
                   NSLog(@"API: TFResponse status: %d", response.status);
                   NSLog(@"API: TFResponse data: %@", response.data);
//                   response.data = responseObject[@"data"];

We have result:

API: TFResponse status: 0
API: TFResponse data: {
}

For fix that, i use:

response.data = responseObject[@"data"];

But maybe it is a bug, and so I decided to report it.

Wait answer.
Best regards,
Ivan.

Hello,

I just found a problem of property name mapping when we have underscore at the middle of the property.

This is linked to
#46

My Model is:

@interface User : NSObject
@property (nonatomic) int user_id;
@property (nonatomic) NSString* registration;
@end

The dictionary is:

{
    registration = "my test registration";
    "user_id" = 10;
}

However OCMapper mapped user_id to userid(without underscore), I guess this is not supposed to be, you may want to map userid to _userid but forgetting the case when we have underscore at the middle.

Ok, I see the code in

    @implementation ObjectInstanceProvider

    // Support underscore case (EX: map first_name to firstName)
    caseInsensitivePropertyName = [caseInsensitivePropertyName stringByReplacingOccurrencesOfString:@"_" withString:@""];

I just saw that automatic underscore mapping from the latest changelog, but what if we want to keep the same name as in he dictionary?

Hello,

could you help me, when I try to run the following command

ObjectMapper.sharedInstance().objectFromSource(self.data, toInstanceOfClass: Message.self) as? Message 

it returns the following error:

2015-03-12 11:31:16.385 websocket[41545:3347379] *** Terminating app due to uncaught exception 'MissingMappingProvider', reason: 'Mapping provider is not set'

I'm forgetting to do something?

Hi,

I reach the point where one of my swift class is calling the following:

self.mapper.objectFromSource(JSON, toInstanceOfClass:MySwiftClass.self)

In the method of class ManagedObjectInstanceProvider:

- (id)emptyInstanceForClass:(Class)class

the call to:

[NSEntityDescription entityForName:NSStringFromClass(class)  inManagedObjectContext:self.managedObjectContext];

will always return nil cause the result of NSStringFromClass(class) will be something like:

"ProjectName.ClassName"

In Objective C, the above method will return an entityDescription if the entityForName parameter is "ClassName".

Do you have an idea on how I can make that call working?

Thanks.

Get rid of instanceProvider property, and instead have an array that holds objects of type @protocol(InstanceProvider).

Implement chain of responsibilities so that the object mapper decides which instanceProvider to use depending on whether class inherits from NSManagedObject or not.

I use an instance of ObjectMapper and then configure it by adding an InCodeMappingProvider as the mappingProvider. For example :

self.mapper_ = [[ObjectMapper alloc] init];
InCodeMappingProvider *inCodeProvider = [[InCodeMappingProvider alloc] init];
[self.mapper setMappingProvider:inCodeProvider];

I have a user object like this :

@interface SSUserStats : SSObject <SSObjectMapping>

@property (nonatomic, strong, nullable) NSNumber * storeCount;
@property (nonatomic, strong, nullable) NSNumber * followerCount;
@property (nonatomic, strong, nullable) NSNumber * followeeCount;

@end

@interface SSUser : NSObject <ObjectMapping>

@property (nonatomic, strong, nullable) NSString  *userId;
@property (nonatomic, strong, nullable) NSString  *email;
@property (nonatomic, strong, nullable) NSString  *username;
@property (nonatomic, strong, nullable) NSString  *firstName;

@property (nonatomic, strong, nullable) UserStats *stats;

@property (nonatomic, strong, nullable) NSString  *profileImageFilename;
@property (nonatomic, strong, nullable) NSString  *headerImageFilename;

@end

When then I try to create a dictionary from a user object and then convert back this dictionary to an object my app crash :

SSUserStats *stats = [[SSUserStats alloc] init];
stats.storeCount = @(42);
stats.followeeCount = @(12);
stats.followerCount = @(21);

SSUser  *user = [[SSUser alloc] init];
user.firstName = @"Adrien";
user.email = @"[email protected]";
user.username = @"flop";
user.stats = stats;

NSDictionary *dict = [self.mapper dictionaryFromObject:user];
NSLog(@"Dic : %@", dict);
User *user2 = [self.mapper objectFromSource:dict toInstanceOfClass:[User class]];
NSLog(@"User2 : %@", [user2 description]);

First log shows :

Dic : {
    debugDescription = "<User: 0x7fa183e0cd20>";
    description = "<User: 0x7fa183e0cd20>";
    firstName = Adrien;
    email = @"[email protected]";;
    hash = 140331679010080;
    stats =     {
        debugDescription = "<UserStats: 0x7fa183e2dde0>";
        description = "<UserStats: 0x7fa183e2dde0>";
        followeeCount = 12;
        followerCount = 21;
        hash = 140331679145440;
        storeCount = 42;
        superclass =         {
        };
    };
    superclass = NSObject;
}

At the third line, my program crash with :

*** Terminating app due to uncaught exception 'NSUnknownKeyException', reason: '[<User 0x7fa183f22360> setValue:forUndefinedKey:]: this class is not key value coding-compliant for the key hash.'

I'm using Xcode 7, iOS 9. It's really sad because I really like this lib and the way it's architectured. My question is why : hash / superclass / debugDescription / description are processed which leads to this crash, Any idea of how I can fix this. Many thanks.

I know that MESRecipePreviewRecipeIngredientViewModel can be converted into a dictionary normally in a standard iOS app project. The moment I moved it to another private pod framework, I saw this error:

*** Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: 'Invalid type in JSON write (MESRecipePreviewRecipeIngredientViewModel)'

Hi, i want to use generic in class. But i dun know how to get it.

let provider = InCodeMappingProvider()
provider.mapFromDictionaryKey("data", toPropertyKey: "data", withObjectType: BrandSimpleWebModel.self, forClass: PaginationListModel<BrandSimpleWebModel>.self) 
ObjectMapper.sharedInstance().mappingProvider = provider                
let paginationListModel = ObjectMapper.sharedInstance().objectFromSource(response, toInstanceOfClass: PaginationListModel<BrandSimpleWebModel>.self) as! PaginationListModel<BrandSimpleWebModel>

class PaginationListModel<T>: NSObject{
var totalPage: NSNumber!
var totalItem: NSNumber!
var currentPage: NSNumber!
var itemPerPage: NSNumber!
var data: [T]!

When i print "data", the result is nil. If i replace var data:[T]! to var data:[BrandSimpleWebModel]! then i can get the data. Please help me. Thank you

The Cocoa Pod is outdated. Kindly update it. Thanks.

Hey, I'd love to see this lib available in Swift 3 so I can implement it in my project.

Thanks 😄

You added automatic conversion from underscores to camelCase in 2.1 (#31), which is great but I think it would be better if it is optional.

I mean, if a property with underscore case found, parse the json node to that, and only try to parse to a camelCase one if a parameter with the exact same underscore case-d name not found.

I have an array and need to a need to map the indexpath.row dictionary to my preconfigured nsobject .
Which files should I import to my project (from the ocmapper library)?
Which the recommended method to configure the mapping?
User *user = [User objectFromDictionary:aDictionary];?

My understanding from the documentation of OCMapper is that if nothing is set, it should automatically map and reverse map an NSDate. But unfortunately, it doesn't. When it is mapping from object to dictionary, it uses the "description" property of NSDate to get the string. But when it converts from dictionary to object, it is unable to convert it back to NSDate, as it doesn't have a matching dateFormatter. The workaround is to set the defaultDateFormatter to a dateFormatter independent of the locale of the device.

Dears,
Suppose I have the objects below:

@interface Author : NSObject
@property(nonatomic, strong) NSMutableArray *posts;
@end

@interface Post : NSObject
@property(nonatomic, strong) NSString *title;
@end

@interface AnotherPost : NSObject
@property(nonatomic, strong) NSString *title;
@end

And the dictionary data like:

{
    "posts": [
        {
            "title": "title 1"
        },
        {
            "title": "title 2"
        }
    ]
}

The statement below will deserialize Author object using Post class for parsing the array data.

Author *author = [Author objectFromDictionary:aDictionary];

My question is how can I configure AnotherPost class for parsing the array data instead of Post class?

It would be appreciate for you to give me some guides.

Thank you:)

I have an object with a boolean property but it never gets set, it's always nil. How should I declare this property?

MyObject {
  var id: NSNumber?
  var userId: NSNumber?
  var state: String?
  var active: Bool?
}

I have json which contains an array of other classes as well so how to do nested mapping between classes.
Example
@interface APIOrganization : NSObject

@Property (nonatomic , strong) NSString *id;
@Property (nonatomic , strong) NSString *name;
@Property (nonatomic , strong) APIPhoto *rmcPhoto;
@Property (nonatomic , strong) NSMutableArray *Service;
@Property (nonatomic , strong) NSMutableArray *osd;
@EnD

Here the APIOrganization class i am using

APIOrganization *ApiOrg = [[ObjectMapper sharedInstance] objectFromSource:orgDict toInstanceOfClass:[APIOrganization class]];
Service is array of class Service class
but i am not getting the array which contain Service

Please guide me its very urgent
@interface APIService : NSObject
@Property (nonatomic , strong) NSString *id;// Doubt

@Property (nonatomic , strong) NSString *name;

@Property (nonatomic , strong) NSString *descriptions;

@Property (nonatomic , strong) NSString *updatedOn;

Hi!

First of all, thanks for the library!

I have a question though. How can I map a nested array with a custom mapped filed? I'll explain with example below.

Having the following json object:

{
"name": "Name",
"associateTags": [
{
"id": 1,
"tagName": "Tag Name"
}
]
}

And the models:

@interface Tag

@Property (nonatomic, strong) NSString *id;
@Property (nonatomic, strong) NSArray *tagName;
@EnD

@interface OuterModel

@Property (nonatomic, strong) NSString *name;
@Property (nonatomic, strong) NSArray *tags;
@EnD

And OuterModel.tags property is mapped as the following:

@"tags":@"associateTags"

The problem is that instead of instantiating NSArray of Tag classes (using the mapped values) it seems like OCMapper tries to instantiate AssociateTag classes.

I've currently ended with renaming Tag model to AssociateTag however it means I'm bound to server side model naming. Having an ability to name classes according to custom mapping would be great. Is this something that is supported or I'm missing something? If it's not supported right now, can you please point the right direction to update the code of the library (class/method name)?

Thanks!

Because the current bundle is not the main bundle, but it's the unit test bundle.
Try using runtime api instead

- (id)processDictionaryFromObject:(NSObject *)object {

if ([NSBundle mainBundle] != [NSBundle bundleForClass:object.class] && [object class] != [NSArray class])
    {
        return object;
    }

Hi!
I use OCMapper with Alamofire in my application (I would think it is quite a common use case), so like in my previous issue (#53), I would appreciate to see an Alamofire extension example in the README. I already updated my app to Swift 3 and thus Alamofire 4.x, and created the extension myself, so I would be happy to create a pull request to update the readme with both examples (for Alamofire 3.x and 4.x). Do you accept pull requests like this?

I will post my solution here soon for anyone to check.

- (NSString *)propertyNameForObject:(NSObject *)object byCaseInsensitivePropertyName:(NSString *)caseInsensitivePropertyName
{
    NSString *result = nil;
    Class currentClass = [object class];
    NSString *key = [NSString stringWithFormat:@"%@.%@", NSStringFromClass(currentClass), caseInsensitivePropertyName];

    if (self.propertyNameDictionary[key])
        return self.propertyNameDictionary[key];

    while (currentClass && currentClass != [NSObject class])
    {
        unsigned int outCount, i;
        objc_property_t *properties = class_copyPropertyList(currentClass, &outCount);

        for (i = 0; i < outCount; i++)
        {
            objc_property_t property = properties[i];
            NSString *propertyName = [NSString stringWithUTF8String:property_getName(property)];

            if ([[propertyName lowercaseString] isEqual:[caseInsensitivePropertyName lowercaseString]])
            {
                result = propertyName;
                break;
            }
        }

        free(properties);

        if (result)
        {
            self.propertyNameDictionary[key] = result;
            return result;
        }

        currentClass = class_getSuperclass(currentClass);
    }

    return nil;
}

Do a null check on properties before calling free
Also do a null check for key?

Hi

I'm trying to map a composite object like this

   mappingProvider.mapFromDictionaryKey("user.name", toPropertyKey: "name", forClass: User.self)

But it doesn't map, nested keys are not supported?

Hi,

I'm not sure this question is relevant but how do you use:

• (void)mapFromDictionaryKey:(NSString *)dictionaryKey toPropertyKey:(NSString *)propertyKey forClass:(Class)class withTransformer:(MappingTransformer)transformer;

in swift?

I always got the following error: Argument withTransformer must precede argument forClass.

Could you post an example of this method used in Swift please.

Thanks.

Can i am able to serialize JSON from NSMutableArray or NSDictionary?
