Cordova Push Plugin Crashes Once Notification is Received iOS

1

Whenever the iOS app (but not Android) receives a push notification, the app crashes.

To recreate the problem:

  1. Add the ios platform to ionic.
  2. Add the cordova push notification plugin.
  3. Build ios and run on device.
  4. Register device for push notifications. (Registration is successful.)
  5. Send push notification to device, with absolutely any payload. (See payload in the logs)
  6. Ionic logs the notification as being received.
  7. After notification is handled (and specifically, after the execution of method didReceiveRemoteNotification in the AppDelegate+notification.m file), the app crashes. Step debugging does not help as after that method I step through assembly code.

I really dug deep in the iOS code here and could not figure out the problem. Anyone else experiencing this?

For me the solution was: remove and add again platform IOS

3

I’ve tried that many times and I still have the same result.

I do not understand point 7 in your first message in this thread. Are you building a ionic app. If so, how do you handle received messages?

5

What happens if you send a push notification if the app is in background. I
OS of your device should handle the nessage without the app.

6

Indeed I’m building an Ionic app. When I send a push notification and the app is in the background, nothing appears.

7

Did you pushed the proper .p12 keyfikes to ionic.
Did you set productionmode to N?
Did you install the right push plugin?

Did you tried With platform Android?

I’m not using the ionic push notifications, as I found they were too slow for my application. I created my own push notification server based on this code https://github.com/argon/node-apn .

I have tried with Android and everything works perfectly well. I’m not sure how familiar you are with the PushPlugin code, but if I comment out line 221 in PushPlugin.m, my app doesn’t crash. If I replace the variable jsCallBack with an empty string @"", then my app doesn’t crash AND the javascript receives the notification. However, as soon as I start putting in real JSON in there things break. If I hard code a string like @“Hi”, the app doesn’t crash but the javascript doesn’t receive the notification.

I don’t have problems with the plugin, neither with pushnotifications in IOS and Android.
I’m afraid I can’t help you because I don’t know what you are doing. As far as I understanding you are not doing it the Ionic way?

10

I figured it out. It was bad javascript code in my rootScope onNotificationReceived method that was being executed.

Wow. I 'm glad you finally find out.
