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 ?
I use the following function (added to UINavigationController
) to customize the push animation:
- (void) pushController: (UIViewController*) controller
withTransition: (UIViewAnimationTransition) transition
{
[UIView beginAnimations:nil context:NULL];
[self pushViewController:controller animated:NO];
[UIView setAnimationDuration:.5];
[UIView setAnimationBeginsFromCurrentState:YES];
[UIView setAnimationTransition:transition forView:self.view cache:YES];
[UIView commitAnimations];
}
I guess you could adapt this code to do whatever animation you want.
