Question

I have one view controller which contains two views (redView, blueView). The views are smaller than the main view.

I want to change from redView to blueView with animation. If use this none animation happens.

[UIView beginAnimations:@"View Flip" context:nil];
[UIView setAnimationDuration:1.25];
[UIView setAnimationCurve:UIViewAnimationCurveEaseInOut];
[UIView setAnimationTransition: UIViewAnimationTransitionFlipFromRight 
                       forView:redView cache:YES]; // !!! I WILL CHANGE THIS

[self.view addSubview:blueView];
[redView removeFromSuperview];

[UIView commitAnimations];

In case I change the code to this, then the animation is ok but the whole mainView animates, something that i do not want to happen. I want only the subViews to flip. I should note that the 2 subviews are in the same position. (frame) Any ideas?

[UIView beginAnimations:@"View Flip" context:nil];
[UIView setAnimationDuration:1.25];
[UIView setAnimationCurve:UIViewAnimationCurveEaseInOut];
[UIView setAnimationTransition: UIViewAnimationTransitionFlipFromRight 
                       forView:self.view cache:YES];

[self.view addSubview:blueView];
[redView removeFromSuperview];

[UIView commitAnimations];

Solution Found:

I use a tempView for which i do the animation. Onto the tempView I add view1 and view2.

[UIView beginAnimations:nil context:nil]; 
[UIView setAnimationDuration:1.0]; 
[UIView setAnimationTransition:UIViewAnimationTransitionFlipFromRight forView:tempView cache:YES];
[tempView addSubview:view2]; 
[view1 removeFromSuperview];
[UIView commitAnimations];

Extra: For a better animation you can use view1.visible = YES , NO instead of addSubview, removeFromSuperView, but they will be allocated all the time
