Hello,

navigationManager didFindAlternateRoutes was working fine for us until we upgraded to v3.13.3. Now it is not firing for us after we upgraded to v3.13.3.

Note that we have not changed any code. The same issue is happening for Android.

Please advise?

Hi,
I used SDK to get public transport route, but the result are different from HERE WeGo (HERE iOS App). And I found the walk time are various. I try modify the walkSpeed of NMARoutingMode, but the walk time of route didn't change. (walkSpeed doesn't work)

If anyone know how to adjust the walk speed over iOS SDK ? Thanks.

sdk version 3.13.2

Currently the App crashes on init NMAMapView with iOS 13

Hello there!
Checked docs and examples, tried setting image as literal, accessing by asset name, setting on NMAMapMarker init, setting it as value (marker.icon = UIImage(named: "marker.png")). Nothing helped.
I can see the marker as an object in debugger and mapView.add(marker) returns true, map scrolls to that place when I pass the same point to set() method of NMAMapView, but I can't see actual marker on a map.
Can't say whether it is my mistake or something's really broken in SDK?

let marker = NMAMapMarker(geoCoordinates: point, image: UIImage(named: "marker.png"))
mapView.add(marker)
let zoom = zoomLevel ?? mapView.zoomLevel
mapView.set(geoCenter: point, zoomLevel: zoom, animation: .linear)

Swift 5, iOS 12.2, project's build target iOS 10.0

I have a recenter button in my turn by turn navigation view.

The logic behind the recenter button is as follows:

• When I press recenter it sets mapTrackingEnabled and mapTrackingAutoZoomEnabled to true.
• When the mapViewDidBeginMovement function is called I set mapTrackingEnabled and mapTrackingAutoZoomEnabled to false.

It only seems to happen when the user's position is in the top left or top right of the map.

Here is a gif showing what happens:

When i try to release the app, with archive, i tried everything... and i receing this...

Code signing "NMAKit.framework" failed.

Hello HERE developers,
I'm having a problem with NMAKit while using pod for installation. In my podfile I've added pod 'HEREMaps' , but after running pod install my project won't compile, and I don't see HEREMaps (or NMAKit) in the list of pod's generated targets : https://monosnap.com/file/rGBzgiM809dn33JD1aq0ta37V0Si1n

Eventually I need to manually add NMAKit.framework to my main project in order for my project to compile, however because NMAKit is not in the pod's generated target, I cannot disable BIT_CODE and submit the archived binary to appstore.

I'm a premium user and this really annoys me. Please investigate and fix this.

This seems to be due to the simulation code path missing a call to startTurnByTurnNavigation.

This works:

    alert.addAction(UIAlertAction(title: "Simulation", style: .default) { _ in
      let source = NMARoutePositionSource(route: route)
      source.movementSpeed = 60
      NMAPositioningManager.sharedInstance().dataSource = source
      
      let navigator = NMANavigationManager.sharedInstance()
      navigator.mapTrackingEnabled = true
      navigator.mapTrackingAutoZoomEnabled = true
      navigator.mapTrackingOrientation = .dynamic
      navigator.isSpeedWarningEnabled = true
      navigator.startTurnByTurnNavigation(route) // <== the important part
    })

I have an rejection to using this library, it is ITMS- 90338 as emailed by Apple, anyone have same issue like me, if so please let me know how to resolved it

Hi HERE,

We use mobile SDK to get transit routing, and have encountered some issues would like to ask you.

1. Wait bus/train time

Start time 3:00, walk 10 min to bus stop, and the bus start at 3:15. Is this 5 min waiting included in total travel time??

I used several times to get public transit routing.

3:00 ----- (10 min walk) --------3:10(bus stop) ------ (20 min travel time)------3:30 arrive
3:05 ----- (10 min walk) --------3:15(bus stop) ------ (20 min travel time)------3:35 arrive
3:10 ----- (10 min walk) --------3:20(bus stop) ------ (20 min travel time)------3:40 arrive

But the bus departure time interval is more than 10 min, you can never arrive the bus stop and just got the bus coming.

Is there any SDK API or parameter setting for get real bus departure time and include the waiting time? In order to get more accurate time estimate, those are better to be considered.

2. bus arrive / departure time

Some vehicles will wait for a while before starting. Is the time from SDK transit routing arrive time or departure time??

Best regards,

Jon Chiang

I use this url to upload new layer
https://cle.api.here.com/2/layers/upload.json?layer_id=1&file=ID%09NAME%09WKT%0AAA%09nam_te%73t%09LINESTRING%28105.805389 20.999508%2C105.805165 20.99895%29&app_id={app_id}&app_code={app_code}

Response is

{
    "storedTilesCount": 1,
    "response_code": "201 Created"
}

Which is okay.

However, I continue to call this API with the same layer_id:
https://cle.api.here.com/2/search/proximity.json?layer_ids=1&proximity=20.999508,105.805389,200&app_code={app_code}&app_id={app_id}

Response is:

{
    "issues": [
        {
            "message": "No layer or no layer covering the area found"
        }
    ],
    "error_id": "05f8a41a-6cb4-4c21-82a4-4a94c35017ce",
    "response_code": "400 Bad Request"
}

Is that because the upload.json API did not upload a new layer?
What was I wrong here?

Thank you.

The instructions say to update the appdelegate with the license key from my credentials. I see an app id and app code but nothing that says license key. Where do I get the license key to use in the sample ios apps?

When driving straight forward on the road, the map always lean left and right randomly. See attached file. (simulation and real driving both show swing)

At the turn, the swing is more obvious.
The direction of the vehicle sign is unstable. It randomly sway to other directions instead of going straight. One severe scenario is when I turn left at the intersection, it shows I turn 180 degree.

How to stop the swing ?? Thanks.

Hi, in your Example GuidanceApp the NavigationManager doesn´t call the NMAManagerDelegate when start the simulated route, I describe the steps below:

• In the info.plist file I have added the Privacy - Location When In Use Usage Description
  permission
• I have set the delegate in the viewDidLoad.
• I am doing the tests in the Xcode simulator.
• The route starts and is drawn correctly but the delegate is not called

Attached route start image:

I await your solution, greetings!!!

sometimes we are getting NMARoutingErrorViolatesOptions
after a while routing same coordinates gives correct response.

is it something like "someting happen on our server please try again" ? )

Hello Sir ,
I just wonder how can we change the voice language when we using the navigation .
I saw there is a NMAVoicePackage there , but not for sure .
Hope can provide some source code for us .
Thanks so much .

Hello,

I'm having a problem with the .ipa file size. Previously I was using older version (v3.1, which I manually added to my project) and everything went fine, the archived .ipa file was around 60MB in size.

However just lately I've updated the framework to the latest version via Pod, and to my astonishment, the archived .ipa file went up to 280MB in size, which is absolutely not an reasonable number. I cannot submit my app in this condition.

Can anyone please check this? Or at least suggest a solution?

Hi,
Is it possible to create NMAMapView without using storyboard.
We are currenty developing ios static library with here maps

All example on Obj-C , Looking for swift updates

I wanna change the speed of voice, Is there any parameter to adjust the speed ?

The following document is a synthesis of a sentence and then adjust the speed of speech, but it is a little complicated.
https://developer.here.com/documentation/ios-premium/api_reference_jazzy/Classes/NMATTSAudioOutput.html#%2Fc:objc(cs)NMATTSAudioOutput(py)speechRate

is it possible to set a padding for bounds ?
we want to achive bounds so that markers not cut off

I have create the markers and overlays with same coordinates. but they didn't at same place

And when I drag the map, overlays can't moved correctly as markers.

enviroment : iOS 12.1

If i implemente any of the NMAMAPGestureDelegate protocol's methods regarding the pan gestures, the map becomes suddenly painfully slow, be it on the simulator or an actual test device.

I am pulling the sdk through cocoapods for a swift projet

Is this a newly introduced bug ? can i roll back to a previous version of the sdk ?

these are the ones i tested :

- (void)mapView:(nonnull NMAMapView *)mapView didReceivePan:(CGPoint)translation atLocation:(CGPoint)location NS_SWIFT_NAME(mapView(_:didReceivePan:at:));

- (void)mapView:(nonnull NMAMapView *)mapView didReceiveTwoFingerPan:(CGPoint)translation atLocation:(CGPoint)location NS_SWIFT_NAME(mapView(_:didReceiveTwoFingerPan:at:));

ENV:
issue encoutered on both Xcode 9.2 / Xcode 10.0
Cocoapods first pulled the 3.6 version and then i tested with 3.5 thinking it s a new introduced bug, but the issue remained

Hi,
We are getting "Signing error: Bundle identifier not specified" error during generating ipa.

looks like your framework file not unsigned unlike other third party framework files we have used before.that is why encountering such error.
Could you provide unsigned .framework file ?

Hi,

I am trying to configure HereMaps for use with out NMAMapView object.
I have implemented few helper methods for that
`

@objc(initializeNMAContext)
class func initializeNMAContext() {
    guard !NMAApplicationContext.isInitialized() && MotionPermissionViewController.isDetermind else { return }
    let context = "NMAContext-Info".readPlist()
    if let appId = context?["appId"] as? String,
    let appCode = context?["appCode"] as? String,
    let licenseKey = context?["licenseKey"] as? String {
        NMAApplicationContext.setAppId(appId, appCode: appCode, licenseKey: licenseKey)
    }
    
    DispatchQueue.main.async {
        NMANavigationManager.sharedInstance().mapTrackingEnabled = true
        NMANavigationManager.sharedInstance().mapTrackingAutoZoomEnabled = true
        NMANavigationManager.sharedInstance().backgroundNavigationEnabled = true
        NMANavigationManager.sharedInstance().backgroundMapTrackingMaximumRefreshRate = 0.2
        NMANavigationManager.sharedInstance().mapTrackingOrientation = .dynamic
        NMANavigationManager.sharedInstance().isSpeedWarningEnabled = true
        
        if let dataSource = NMAHEREPositionSource() {
            NMAPositioningManager.sharedInstance().dataSource = dataSource
            dataSource.setBackgroundUpdatesEnabled(true)
        }
    }
}

@objc(isPositioning)
class func isPositioning() -> Bool {
    return NMAApplicationContext.isInitialized() && NMAPositioningManager.sharedInstance().isActive
}

@objc(startPositioning)
class func startPositioning() {
    guard NMAApplicationContext.isInitialized() else { return }
    if !NMAPositioningManager.sharedInstance().isActive {
        BackgroundTask.run(queue: .main) { task in
            _ = NMAPositioningManager.sharedInstance().startPositioning()
        }
    }
}

@objc(stopPositioning)
class func stopPositioning() {
    guard NMAApplicationContext.isInitialized() else { return }
    NMAPositioningManager.sharedInstance().stopPositioning()
}

`

And I do listen to NMAPositioningManagerDidUpdatePosition notification
However, currentRoadElement is always null in there.

Can you help me with it?
What is the correct use case for background execution with out maps.
No maps I mean:
There is no NMAMapView object
Nothing is displayed on the screen.

(We are talking about realtime use-case)

Hi we did not found any mapupdatemode for ios sdk
we were using this to achive real turn by turn navigation with android sdk

also mapview.tilt=80 also ignored

we want to achive this skyvisible tilting more realistic turnbyturn

public static final MapUpdateMode ROADVIEW

Map updated using NavigationManager.RoadView, with zoom level automatically adjusted according to the approaching maneuver, road type and speed

In Java´s SDK version there is a method called

boolean onMapObjectsSelected(java.util.List<ViewObject> objects)

(https://developer.here.com/documentation/android-starter/api_reference_java/com/here/android/mpa/mapping/MapGesture.OnGestureListener.html).

Is there a corresponding iOS implementation?

All I can find is

-(void)mapView:(NMAMapView *)mapView didReceiveTapAtLocation:(CGPoint)location

to handle tapEvents. (https://developer.here.com/documentation/ios-premium/dev_guide/topics/map-gestures.html)

How could I implement such a behavior on my own?

Thanks!

Hi,
i have an issue about return value of detailRequest from NMAPlacelink. I try the code below:

` self.searchLinkResults[indexPath.row].detailsRequest().start { (request, responseData, error) in
guard error == nil else{
return
}

            if request is NMAPlaceRequest{
                if let place = responseData as? NMAPlace{
                    debugPrint(place.name)
                    debugPrint(place.location?.address?.city)
                    debugPrint(place.location?.address?.county)
                    debugPrint(place.location?.address?.state)
                    debugPrint(place.location?.address?.street)
                    debugPrint(place.location?.address?.district)
                }
            }
        }

`

the result is address.city and address.district is same value but is not valid, but if i use geocoding function is valid and have same value.

is that a bugs or issue, or should i to use geocoding function?

thanks!.

I am using HERE maps for navigation functionality in my project. Navigation is working fine, but now I want to display the textual directions on the screen.

I could find the list of ENums that return integer values for the turns taken

but am clueless on how to use this data to represent the text for turns on the screen as they return just integer numbers, not a text.

For example:

If left turn is taken it gives me 9 instead of "Take a quite left".

This solution is available in android but I don't know to how to work it out in iOS.

Any help is appreciated, thank you.

@abdullahselek I'm using here maps in one of my apps. And I have to show map on at least 3-4 screens. So there will be 3-4 map instances loaded in memory all time.

What I have noticed is that loading one instance of here maps consumes up to 50MB of memory. As soon as I move to other screen hence two instances of map are loaded. Memory jumps to 100MB and so on and so forth. Finally after using sometime, the app crashes with memory issue.

"Got memory pressure notification (critical) 2017"

I'm adding purchased version of here maps through pods. Does it make any difference?

Hi all,
I'm currently experiencing some weird issues with markers and polylines. When placing a marker on the current user position and adding a dashed polyline to a specific destination, they can be moved by scrolling the mapview. This does not happen with the marker at the destination. Furthermore, they positions align when positioning in the middle of View. I already played around with the transformCenter property without any success.
I have attached a screenrecord that shows the unexpected behaviour. Any help in this regard would be highly appreciated, since this issue is bugging me for days.

Hi,

as it looks for me, the [NMAMapLoader sharedMapLoader] doesn't work properly in my application. Its busy all the time.

NSArray<NMAMapPackage*>* toInstall = [[NSArray alloc] initWithObjects:_germany, nil]; BOOL res1 = [_mapLoader cancelCurrentOperation]; BOOL res2 = [_mapLoader installMapPackages:toInstall];

In my code I try to install a NMAMapPackage. I call 'cancelCurrentOperation' before 'installMapPackages'. res1 (cancelCurrentOperation) is true, but installMapPackages still won't be executed correctly and returns false.

There is no warning message in my output window.
Version of HEREMaps Sdk: 3.7.0

You got any information about why the mapLoader is busy and what to do that it finishes its tasks?

Thanks!

Hi,

when running the GuidanceApp / Turn-by-turn-navigation project, the navigationManagerDidFindPosition function is never called. Neither using the simulation mode nor using "real navigation" with a custom .gpx-file or apple's location examples.

When does the NavigationManager delegate normally calls this method?

Thanks for your help.

Dear support team of Here Map SDK.

I have read your guide about map-matching.

https://developer.here.com/documentation/ios-premium/dev_guide/topics/map-matching.html

I really want to use map-matching apis.
I am going to draw my movement onto the road while driving.
At this time, I don't specify the destination.
However, because of the GPS coordinate error, I couldn't draw the correct path on the map. It often crosses buildings and is drawn onto unexpected location.
I am so excited to visit the above topic.

However, I couldn't see any method how to use map-matching apis.
Please offer simple demo code for the map-matching.

Hi!

I have an error using NMAMapView in iOS 13.

This error happens only in iOS 13. The crash occurs in the simulator.
In iOS 12 or 11 it works correctly.
The version is "HEREMaps 3.12.2"

where we can download dsym file to symbolicate crash logs ?
this file is included in many sdks like mapbox

Hi

I try to compile turn-by-turn-navigation-ios-swift.
I put appID, appCode and licenseKey into AppDelegate.swift, modify Bundle Identifier, and run "pod install" on turn-by-turn-navigation-ios-swift folder.

Then I run build function, 1 error occurred: "Library not found for -lPods-GuidanceApp"

What can I do for this?
What procedure I missed?

Hi,
My use case is out of the bounds. I want to use here maps for location data. However, I do not want to display map view.

NMAPositioningManager is what I need including realtime updates. However, currentRoadElement isn't there if the map wasn't downloaded first.

I am using NMAMapLoader to download MapPackage for given NMAGeoCoordinates.
The problem is even if I do download and install that while the currentRoadElement is nil under NMAPositioningManager.
With the next iteration (NMAPositioningManager update) nothing changes.
How can I retrieve currentRoadElement with speed limit data with out using NMAMapView ??
With out navigating user and creating routes?

I just want to pass current location and get road element for it. How do I achieve it?

i need a documentation for the HERE map SDk using swift 3
All the examples written with objectiv-c iam trying to build a HERE Map Street-level Imagery
project using swift 3 >>>please contact me ASP

Today I've downloaded your sample projects, and tried running 'pod install', but I get this error:
[!] Unable to find a specification for HEREMaps

Can you guys please check your pod project?

According to document (https://developer.here.com/documentation/ios-premium/dev_guide/topics/map-guidance.html), when user is far from a road, turn by turn navigation may not start immediately.

But sometimes, user followed the route for a while (on the road), the navigation still didn't start.

And sometimes, the navigation engine start at the beginning, but suddenly it stopped working and never to wake again.

How to handle these kind of situations? Is there any callback can be used for reset navigation manager engine ?? Thanks.

getMapPackageAtGeoCoordinates returns true, but does not call mapLoader:didGetMapPackage:atGeoCoordinates:withResult.

SDK Version: 3.7.0.118

We're trying to integrate the Here SDK but are experiencing SIGABRT crashes when instantiating a NMAMapView. I know that this works in your sample project so I assume there are some other configuration differences.

libsystem_kernel.dylib`__pthread_kill:
    0x1168752bc <+0>:  movl   $0x2000148, %eax          ; imm = 0x2000148

    0x1168752d0 <+20>: retq   

After researching a bit this seems to be a common issue (see this Twitter thread for example).
I'm currently in the process of capturing more logs, but please let me know what kind of other information you'd need in order to debug this.

Hey!
I am integrating here map sdk in my iOS App.All good with that the only problem I am facing there is I am unable to calculate the route. I am following the user guid provided by you.All code is setup well and I installed here map using cocoapods.
Here I am presenting the piece of code where I am falling.

coreRouter.calculateRoute(withStops: stops as! [Any], routingMode: routingMode) {(routeResult, err)

in

print("I am unable reach Here...")

    } 

As I understand calculateRoute func is unable to revoke completion handler.
The configuration I am using here is like-Swift 3.2, Xcode-8.3.2

Hi there!
I downloaded and run map-downloader-ios-swift project and it worked well. After finished download 1 region, how do we show that region in mapview without an internet connection? And is it possible to add routes in that downloaded region in offline mode?
