Description Yevgeniy Goyfman 2009-10-15 07:32:04 UTC 
Steps to replicate:

1)  Compile and run any of the Demo projects for iPhone 3.0
2)  Screen will display SLD "Loading" screen
3)  SDL "Loading" screen is not replaced by the application's graphics/UI

Demo apps are being compiled under OSX 10.6 with XCode 3.2

Please note that compiling for iPhone 2.x targets works fine.  There are no errors reported by SDL or by iPhoneOS itself during the execution of the program

appDidFinishLaunching is triggered before all the setup's complete. The easiest fix is to arrange for another event to be sent when it's really ready, and run SDL_main from there. Ref. http://blog.rightsprite.com/2008/11/iphone-applicationdidfinishlaunching.html

SDL-1.3.0-4563/src/video/uikit/SDL_uikitappdelegate.m:



- (void)postFinishLaunch {
	
	/* run the user's application, passing argc and argv */
	int exit_status = SDL_main(forward_argc, forward_argv);
	
	/* free the memory we used to hold copies of argc and argv */
	int i;
	for (i=0; i<forward_argc; i++) {
		free(forward_argv[i]);
	}
	free(forward_argv);	
		
	/* exit, passing the return status from the user's application */
	exit(exit_status);
		
}

- (void)applicationDidFinishLaunching:(UIApplication *)application {
			
	/* Set working directory to resource path */
	[[NSFileManager defaultManager] changeCurrentDirectoryPath: [[NSBundle mainBundle] resourcePath]];

	[self performSelector:@selector(postFinishLaunch) withObject:nil afterDelay:0.0];
}
