问题 I have an application with a UITabBarController at its top level. I track which tab a user is on and store it so that when they reopen the application they are on the tab they were on when it was closed. So there is no default tab when the app starts up. I have a modal screen that shows first every time the app starts. It doesn't matter which tab was saved, the user is always presented with this view. Where should this modal view be presented from?

[self.window addSubview:viewController.view]; [self.window makeKeyAndVisible]; VC_A then loads VC_B by using presentModalViewController : VC_B *tempView = [[VC_B alloc]

问题 I'm getting the following runtime error and I cannot determine for the life of me WHYYYY. The error is Thread 1: EXC_BREAKPOINT (code=EXC_1386_BPT, subcode=0x0) which seems to happen whenever I execute the dismissModalViewController:animated or the pushViewController:animated method from any of my VC's.

问题 -(void)reviewClicked:(id)sender { ReviewViewController *newView = [[ReviewViewController alloc] init]; newView.delegate = self; UINavigationController *navCon = [[UINavigationController alloc] initWithRootViewController:newView]; [self presentModalViewController:navCon animated:YES]; } I have a splitViewController setup, which is what is probably causing some issues.
