Question

I want to call “presentmodalviewcontroller” when the iPhone / iPod Touch is rotated to landscape mode with a flip animation. When it gets rotated back to portrait, I want to present the first view again, again with the flip animation.

Weren’t able to find something working on the web 🙁

I’m sure you can help me 🙂
Thanks a lot !

Answer 1

In your UIViewController, accept all interface orientations:

-(BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation
{
return YES;
}

And your controller will start receiving rotation messages, like:

- (void)willAnimateRotationToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation duration:(NSTimeInterval)duration

and

- (void)didRotateFromInterfaceOrientation:(UIInterfaceOrientation)fromInterfaceOrientation

Where you can react to rotation and do things like present/dismiss modal viewcontrollers.
