I have a view controller that I am presenting with the following objective c code:

ani         


        

Answer 1

Presenting a view controller using a custom animation:

CATransition* transition = [CATransition animation];
transition.duration = 0.3;
transition.type = kCATransitionMoveIn;
transition.subtype = kCATransitionFromRight;
[self.navigationController.view.layer addAnimation:transition forKey:kCATransition];
[self.navigationController pushViewController:reader animated:NO];

Dismissing a view controller using a custom animation:

CATransition* transition = [CATransition animation];
transition.duration = 0.3;
transition.type = kCATransitionReveal;
transition.subtype = kCATransitionFromLeft;
[self.navigationController.view.layer addAnimation:transition forKey:kCATransition];    
[self.navigationController popViewControllerAnimated:NO];
