Fixed bug #847
Roger Willcocks 2009-10-25 08:45:37 PDT
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.

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];
