Why doesn't this code work?

Question

    SignView *tempVC = [[SignView alloc] initWithNibName:@"SignView" bundle:Nil];
[UIView beginAnimations:nil context:nil];
[UIView setAnimationTransition: UIViewAnimationTransitionCurlUp forView:self.view cache:YES];
[UIView setAnimationDelay:0.5f];
[UIView setAnimationDuration:2.0f];
[UIView commitAnimations];
[self presentModalViewController:tempVC animated:YES];
[tempVC passDataWithString:button2.titleLabel.text andColor:currentlySelectedColor isNightModeOn:nightMode.on];

The view slides up instead of Curling up.

What am I doing wrong?

Answer 1

To set the transition style of a modal view controller, set it's modalTransitionStyle property.

self.modalTransitionStyle = UIModalTransitionStylePartialCurl;

Also note that some transition styles don't look right on the simulator, but should be fine on the device.
