Eric Wing to Sam, hfutrell 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 -Eric On Nov 23, 2009, at 1:43 AM, Sam Lantinga wrote: > I ran into a blocking startup crash with the Happy demo on iPhone OS 3.1.2 on my new iPhone: > > #0 0x323fea14 in _class_isInitialized > #1 0x323fea68 in _class_initialize > #2 0x32403e92 in prepareForMethodLookup > #3 0x32401244 in lookUpMethod > #4 0x323fea10 in _class_lookupMethodAndLoadCache > #5 0x323fe746 in objc_msgSend_uncached > #6 0x323feb26 in _class_initialize > #7 0x323fea58 in _class_initialize > #8 0x32403e92 in prepareForMethodLookup > #9 0x32401244 in lookUpMethod > #10 0x323fea10 in _class_lookupMethodAndLoadCache > #11 0x323fe746 in objc_msgSend_uncached > #12 0x000554dc in UIKit_GL_CreateContext at SDL_uikitopengles.m:103 > #13 0x0004f89e in SDL_GL_CreateContext at SDL_video.c:3155 > #14 0x000579e8 in GLES_CreateRenderer at SDL_renderer_gles.c:282 > #15 0x0004d7b8 in SDL_CreateRenderer at SDL_video.c:1509 > #16 0x00002bc2 in SDL_main at happy.c:156 > #17 0x000571b2 in -[SDLUIKitDelegate postFinishLaunch] at > SDL_uikitappdelegate.m:77 > #18 0x313f9ef2 in __NSFireDelayedPerform > #19 0x32567bb2 in CFRunLoopRunSpecific > #20 0x3256735c in CFRunLoopRunInMode > #21 0x32912cbe in GSEventRunModal > #22 0x32912d6a in GSEventRun > #23 0x32b6276e in -[UIApplication _run] > #24 0x32b61472 in UIApplicationMain > #25 0x00057088 in main at SDL_uikitappdelegate.m:50 > > Any ideas? > > See ya! > -- > -Sam Lantinga, Founder and President, Galaxy Gameworks LLC
