and i got exception at here :
gsCrashReporterUEHandler NSUncaughtExceptionHandler * (flashcards`uncaught_exception_handler) 0x01bf1a38
any idea, what error i found here ?

Answer 1

In your crash log I can see this error:
Uncaught exception: NSInternalInconsistencyException: UnityDefaultViewController should be used only if unity is set to autorotate.
This means Unity should set Screen.orientation to ScreenOrientation.AutoRotation.
You can check if some code in your Unity3D project set the Screen.orientation to any other code and check in "Unity Build setting" Default Orientation is "Auto Rotation".

Answer 2

We got this crash report also, and many of them
I've read somewhere (maybe in Unity forum) that it's being caused by Ads that showing in different orientation, when the game is back from Ads, the orientation did not restore correctly so Unity log the ASSERT.
They suggested that we just need open the exported XCode project and comment out the ASSERT line 111 in the file UnityViewControllerBase+iOS.mm
Well, we did and it's working for us!!!
//
// Just in case the attached screenshot expires
//
- (NSUInteger)supportedInterfaceOrientations
{
//NSAssert(UnityShouldAutorotate(), #"UnityDefaultViewController should be used only if unity is set to autorotate");
return EnabledAutorotationInterfaceOrientations();
}
