Can you recreate it in a stripped down version; i.e., only the app delegate class, gl view class and touch code that registers an NSLog? If so, can you provide this code to examine?


As for a view controller, it's completely up to you. It won't slow down your rendering code any more than it is now and you can leave all the engine and rendering code in C++ even if you switch to the view controller setup. In my experience, if you don't stick with Apple's templates, you'll almost always have some headaches in the future with other things not quite working right. I *think* Game Center would also require you to work with view controllers, for instance, though I'm not sure on that since I haven't yet integrated GC into anything. It is of course your choice though!
