Question

I have a modal with some options on it for my iPad App. When an option is selected I want to remove the modal then segue to a new screen.

I want the original screen (that launched the modal) to be seen for two seconds before the new segue happens. Why will this code not work?

[self dismissModalViewControllerAnimated:YES];
sleep(2.0);
[self performSegueWithIdentifier:@"normalPushSegue" sender:self];

This is what happens: When a button on the modal is pressed it freezes for two seconds then transitions extremely quickly to the normalPushSegue screen. Even if I put the sleep command into prepareForSegue it still does the same thing.

Any ideas? Are there any other ways to delay a segue?

Answer 1

Use performSelector:afterDelay: instead:

[self performSelector:@selector(performSegueWithIdentifier::) withObject:@"normalPushSegue" withObject:self afterDelay:2];
