You forgot [[self sourceViewController] presentModalViewController:[self destinationViewController] animated:NO]; in perform method, isni't ?

Nope he didn't. This is a custom push segue. And by the way presentModalViewController:animated: is deprecated, if you want to make a custom modal segue use presentViewController:animated:completion: :)
