iOS9 UnityAdBanner Crash

Question

This has been happening for quite some time but simply noted that as everything was still early beta that we should expect crashes. But now that iOS9 is getting closer to final release -- this is starting to worry me.

I have an game that's been on the App Store and running on all devices running iOS6 through 8.4.1 with no reported crashes.

On the latest version of iOS 9 Beta and Xcode Version 7.0 beta 6 (7A192o), my game is crashing when showing/closing iAds -- both interstitial and banner:

 Terminating app due to uncaught exception 'NSInternalInconsistencyException', reason: 'accessing _cachedSystemAnimationFence requires the main thread'
 *** First throw call stack:

 libc++abi.dylib: terminating with uncaught exception of type NSException

I am by no means an Xcode or iOS SDK/Objective C expert -- far from it -- which is why I use Unity.

I am building with Unity 5.1.3p1, IL2CCP

Any ideas?

Thanks, Manny

Hi Manny, I've been experiencing a similar issue. I have a solution based on this SO response (http://stackoverflow.com/questions/12005261/removefromsuperview-doesnt-work), but I don't know if it'll work to fix UnityAds, as for me it'll only crash when I publish to the store, and I have to wait about a week to do that.

In your Xcode Project

Go to the Project Navigator

Select UnityAppController.mm

Replace

[_snapshotView removeFromSuperview];

With

[_snapshotView performSelectorOnMainThread:@selector(removeFromSuperview) withObject:nil waitUntilDone:NO];

Build and hope for the best
