Problem with getting IOS device token.

I'm trying to use the Unity API get IOS device token to register push notification. The difficulties I found that the UnityEngine.iOS.NotificationServices.deviceToken always throw me null value.

When the app calling RegisterForNotifications, xcode did throw the token back with result below.
2016-04-26 17:52:56.445 ****[869:1651521] [NotifyEventListener] Method=DidRegisterRemoteNotification, Message=38db43d982215985afd4ce149227eec4b4b260196fda56df13d246c95b76d8b6

But after that comes to deviceToken, it was still null even through I tried to invoke the methods again.
Current implemented Unity version was 5.3.4 and xcode was 7.3.

Here is my C# codes that I tried to implement the Amazon SNS to mobile application. For android was successfully to register endpoint with token. Left only the iphone keep throwing null token while trying to register.
As further checked my Unity in Mac version was 5.3.4f1 that showing latest version.

 

I tried this way also get same result as null always in iOS with 5.3.4f1.

 

I tried further checked found while invoke the method NotificationServices.RegisterForNotifications, the xcode log show Method=DidRegisterRemoteNotification, Message={token}.
Then come to NotificationServices.deviceToken, the xcode log show SendMessage: object NPBinding not found!

 

I found the issue was caused by the cross platform native plugin Ultra pack that earlier imported. The plugin did modify the xcode notification service behavior when the setting of notification service enabled for the plugin. After disabled the plugin setting, it works to get token from ios again.

 

I don't know why this setting remain default off in xCode 8.1



After changing toggle to ON, its working correctly.
Other from last 4 hours I was getting NULL from deviceToken.

In previous version of xCode its working without any kind of settings.
I hope this become useful to someone

 

Anyone know a way to automate this toggle so I can have it done from my Unity build?

Solved: See this great post by @a_p_u_r_o.

 

You've just saved me hours! Exactly what I was hunting for. Thank you my friend!!

 

So I turned push notification capability on in XCode but still the device token is null with UnityEngine.iOS.NotificationServices.registrationError being empty.

However in the XCode console I only see the Debug.Log outputs from within Unity code. How do you guys get to see the XCode system logs?

 

Hello,
I couldn't make "ISN_RemoteNotificationsController. RegisterForRemoteNotifications" work.

Is there anything that I need to know? Push notifications are enabled in "stans assets settings" and also "XCode capabilities. Thanks in advance.

 

Try to enable Symlink Unity Libraries chekcbox in Build Setting

 

I have done this thing also...but noting is displaying on console
