iOS IAP Crash

[appetizermonster]

SDK Version: OneSignal-Unity-SDK v2.1.4

I used OneSignal-Unity-SDK in my iOS unity game. (Internally, the game uses UnityIAP)
In OneSignal-Unity-SDK v2.1.3, I tried to purchase in-app items, my game always crashed.
and it seems it has fixed in v2.1.4.

but crash happens again in v2.1.4 (maybe it's the worst)

Here is how to reproduce:

1. Make in-app purchases
2. Close app (terminate) before success message appears
3. Run app again, and you will see app crash
   and You can't run app again. (it's worst)

and I workaround this issue by replacing OneSignal-iOS-SDK library with removing IAP Tracking.

@appetizermonster Can you attach the full crash log as well? The stack trace is most likely different.

Thanks.

@appetizermonster Thanks! The issue is due to SKProductsRequest not being cleanup on de-allocation. Added clean up for this and prevented a 2nd instance of the IAP tracking class which will prevent any other possible race conditions.

Since you have a test device in this state already can you confirm that this build fixes the issue?

Extract it to Assets/OneSignal/Platforms/iOS/libOneSignal.a and replace the existing one.

You should be able to just to redeploy your app (without uninstalling) and the app should run correctly again.

We had the same problem and the libOneSignal.a file you provided fixed the issue.

We were using OneSignal 2.1.4

The error we had was:

@appetizermonster @yamanyar This fix is now included in our 2.2.0 Unity SDK release.
