This one is quite puzzling. I found a partial workaround, but I don't fully understand the reasons yet.
First, the console is complaining about not finding a nib for MainWindow.
I tried removing the entry for this in the info.plist, and the message went away, but it didn't really change anything.
Second, I stepped through this with the debugger and broke up some lines. It seems that the basic act of calling
view = [SDL_uikitopenglview alloc];
or even
view = [SDL_uikitview alloc]
will crash the program. The debugger messages plus the stack trace make me think it's not finding the SDL_uikitview classes for some reason. But I don't understand why this would be.
view = [UIView alloc] will not crash the program.
For kicks, I added a new definition of a class called SDL_object which subclasses NSObject in the same files as SDL_uikitopenglview and then call
view = [SDL_object alloc];
This does not crash the program.
So, then I modified SDL_object to subclass UIView. No crash.
Next, I made SDL_object subclass UIView<UITextFieldDelegate> . This crashes.
So it is the act of conforming to the UITextFieldDelegate protocol that is crashing things.
I don't understand why it would crash on alloc though. I'm guessing either a delegate needs to be set somewhere or one of the required methods needs to be implemented. But in the former case, I would not expect a crash, but a silent message to nil and something else doesn't work. And in the latter case, I would expect a compiler warning and an exception thrown instead of a crash.
Anyway, my temporary workaround is to change the interface declaration for SDL_uikitview to look like:
#if SDL_IPHONE_KEYBOARD
@interface SDL_uikitview : UIView<UITextFieldDelegate> {
#else
@interface SDL_uikitview : UIView {
#endif
And then disable the keyboard support in the SDL_config_iphoneos.h file.
/* enable iPhone keyboard support */
#define SDL_IPHONE_KEYBOARD 0
