I've declared an alert view message ,but it's never shown:
if (![text validateMinimumLength:8]) { field.alertView.title = @"Password is too short"; return NO; } else { return YES; }

I'd like to override some values, such as DEFAULT_LEFT_INDICATOR_INACTIVE_ASPECT_RATIO
, in my app and wondering how this should be done.

For example, if this was a @Property then it could be changed easily. Please do point out if it is possible to override a #define, as you have here.

Hi again! Just wanted to ask what you think about including the instance of the bzgformfield on the textvalidation block? I think it would be more convenient as opposed to having to use weakSelf to access the bzgformfield inside the validation block.

typedef BOOL (^BZGTextValidationBlock)(BZGFormField *field, NSString *text);

//Setting validation block
[self.formField setTextValidationBlock:^BOOL(BZGFormField *field, NSString *text){

//Validate text

//Add error message
field.alterView.title = @"Error Message.";

}];

Thanks!

:)

Let me know if you need help making a podspec.

Please guide me to handle empty field validation.

Thank you.

When I try to load the class in view, I get this error.
Unknown class BZGFormField in Interface Builder file.

Hi,
I am trying to add BZGFormField on UITextField. However, I am getting following errors. Please guide me, how to add BZGFormField on UITextField.

---.h file -----

import <UIKit/UIKit.h>

import "BZGFormField.h"

@protocol BZGFormFieldDelegate;

@interface AuthenticationViewController : UIViewController

@Property(strong,nonatomic) UITextField BZGFormField *emailField;
@Property(strong,nonatomic) UITextField *passwordField;
@Property(strong,nonatomic) UITextField *passwordConfirmField;

-(void)loadLoginForm;
-(void)loadRegistrationForm;
@EnD

import "AuthenticationViewController.h"

import "BZGFormField.h"

@interface AuthenticationViewController ()

@EnD

@implementation AuthenticationViewController

• (void)viewDidLoad
  {
  [super viewDidLoad];
  // Do any additional setup after loading the view.
  [self loadLoginForm];
  }

-(void)loadLoginForm
{
NSLog(@"AuthenticationViewController loadLoginForm");

self.emailField = [[UITextField alloc] initWithFrame:CGRectMake(10, 10, 230, 30)];

self.emailField.text = @"";
self.emailField.placeholder = @"Email";
self.emailField.borderStyle = UITextBorderStyleRoundedRect;
   [self.emailField setTextValidationBlock:^BOOL(BZGFormField *field, NSString *text) {
    // from https://github.com/benmcredmond/DHValidation/blob/master/DHValidation.m
    NSString *emailRegex = @"[A-Z0-9a-z._%+-]+@[A-Za-z0-9.-]+\\.[A-Za-z]{2,4}";
    NSPredicate *emailTest = [NSPredicate predicateWithFormat:@"SELF MATCHES %@", emailRegex];
    if (![emailTest evaluateWithObject:text]) {
        field.alertView.title = @"Invalid email address";
        return NO;
    } else {
        return YES;
    }
}];
self.emailField.delegate = self;
[self.view addSubview:self.emailField];

}

@Property(strong,nonatomic) UITextField BZGFormField *emailField;
Error :

---Cannot declare variable inside @interface or @protocol

[self.emailField setTextValidationBlock:^BOOL(BZGFormField *field, NSString *text) {
Error:
---No visible @interface for 'UITextField' declares the selector 'setTextValidationBlock:'

The example for setting a validation block is

[self.passwordField setTextValidationBlock:^BOOL(BZGFormField *field, NSString *text) {
    if (text.length < 8) {
        field.alertView.title = @"Password is too short";
        return NO;
    } else {
        return YES;
    }
}];

When I do this however, I get

May the example be outdated?

That would be amazing!

Great Library!

Hi all! I plan to extend this library to support a 'required' boolean. Fields that are required will be marked differently while they are empty. If they have text then normal validation will take place.

Let me know your thoughts on this! I wil use similar UI to the invalid UI (not sure exactly what it will look like)

thanks!
