Title Body

I want to show a custom animation when pushing a view controller: I would like to achieve something like an "expand" animation, that means the new view expands from a given rectangle, lets say [100,100 220,380] during the animation to full screen. Any suggestions where to start, respectively any documents, tutorials, links? :) Alright. I could make the expand animation with the following code: if ([coming.view superview] == nil) [self.view addSubview:coming.view]; coming.view.frame = CGRectMake(160,160,0,0); [UIView beginAnimations:@"frame" context:nil]; [UIView setAnimationDuration:4]; [UIView setAnimationCurve:UIViewAnimationCurveEaseInOut]; [coming viewWillAppear:YES]; [going viewWillAppear:YES]; coming.view.frame = CGRectMake(0, 0, 320, 480); [going viewDidDisappear:YES]; [coming viewDidAppear:YES]; [UIView commitAnimations]; My View is properly displayed, but unfortunately the navigation bar is not updated. Is there a way to do that manually? In the sample code, a function is called all 0.03 seconds that updates the transformation of the view. Unfortunately, when pushing a UIViewController , I am not able to resize the frame of the view ... am I ?
