According to the docs:
> @property(nonatomic, assign) BOOL providesPresentationContextTransitionStyle
> Discussion
> If the value of this property is YES and the value of the
> definesPresentationContext property is YES, then the modal transition style
> of the presenting view controller is used. Otherwise, the modal transition

So I tried it and it doesn't work. I simply used Xcode's built-in Utility
Application template, which presents and dismisses a modal view right out of
the box:
- (IBAction)showInfo:(id)sender
{
FlipsideViewController *controller = [[FlipsideViewController alloc]
initWithNibName:@"FlipsideViewController" bundle:nil];
controller.delegate = self;
controller.modalTransitionStyle = UIModalTransitionStyleFlipHorizontal;
// here are my additions
self.modalTransitionStyle = UIModalTransitionStyleCrossDissolve; // *
self.providesPresentationContextTransitionStyle = YES; // *
self.definesPresentationContext = YES; // *
[self presentModalViewController:controller animated:YES];
}
The three marked lines are my only change to the template. I am doing exactly
what the docs say to do. But it isn't working, or rather it's working in a very
lame and partial way: the transition is flip horizontal when the modal view is
shown, but it is cross dissolve when the modal view is dismissed. Other
combinations of the presented modal view controller's transition style and the
presenting modal view controller's transition style get even weirder and can
even cause the app to crash.
What most amazes me is that I can't find anyone else complaining about this
online. Hence this note. Either I'm doing this totally wrong or the docs are
describing it incorrectly or no one in the world has actually tried this except
me! Thx - m.
