Question

There is a vertical cover transition. I have been looking around the web for how to do a horizontal cover with no success. Any suggestions?

Answer 1

There’s no horizontal cover transition provided in iOS. You’ll have to create your own UIStoryboardSegue subclass and implement your own transition animation.

One way to animate the kind of transition I think you’re looking for is something like this (warning: untested code):

// add newView to window
[oldView.window insertSubview:newView aboveSubview:oldView];

// assuming newView and oldView both sized to fill screen,
//   position newView just to the right of oldView
newView.center = oldView.center + oldView.frame.size.width;

// slide newView over oldView, then remove oldView
[UIView animateWithDuration:0.3
                 animations:^{ newView.center = oldView.center; }
                 completion:^(BOOL finished){ [oldView removeFromSuperview]; }];
