Я нашел ответ, поэтому поделюсь.
- (void)clickHandler{
// create an image that looks exactly like
// the preview image in your scroll view (can leave off the toolbar/statusbar if you like)
UIImage *img = [UIImage imageNamed:@"something.png"];
// create an imageview to hold the image
UIImageView *iv = [[UIImageView alloc] initWithImage:img];
// ensure that the frame is set so that it's directly over the image in your scrollview
iv.frame = CGRectMake(60, 150, 200, 200);
// push the image into the superview over top this controller's view
[[self.view superview] insertSubview:iv aboveSubview:self.view];
// refresh superview NOW
[[self.view superview] performSelectorOnMainThread:@selector( setNeedsDisplay ) withObject:nil waitUntilDone:YES];
//-----------
//animate the image to bring it from it's "scrollview size" to the size it will be after the transition.
[UIImageView beginAnimations:nil context:nil];
[UIImageView setAnimationDuration:0.3];
iv.frame = CGRectMake(0, 65, 320, 371);
[UIImageView commitAnimations];
//-----------
// transition to the new view using the CrossDissolve transition (or just don't animate it.)
NewViewController *controller = [[NewViewController alloc] initWithNibName:@"NewView" bundle:nil];
controller.modalTransitionStyle = UIModalTransitionStyleCrossDissolve;
[self presentModalViewController:controller animated:YES];
[controller release];
// set the animated imageview to remove itself after a delay
// (after the new view is transitioned into place below it.)
[iv performSelector:@selector(removeFromSuperview) withObject:nil afterDelay:0.3];
// be sure to release where needed and all that, I may have cut too much from the code for this snippet.
// this may not be the best example, but it does work.
// please post any improvements back so that we can all benefit
