I am showing this modalView and it does not handle touches. I am using cocos2d-iphone.
mControllerView= [[UIViewController alloc] init];
//mControllerView.view = [[CCDirector sharedDirector] openGLView];
//this was the old method, it worked, but since ios6 it crashes
[[[CCDirector sharedDirector] openGLView] addSubview:mControllerView.view];
theClass = [[TheClass alloc] init: mControllerView];
// this shows the GKMatchmakerViewController inside mControllerView
I have changed cocos2d to a newer version, and didn't check what changed, or what should I refactor in the appDelegate. Now it works.
