[iPhone] Switch UIViews

Question

Hi.
I just have a pretty basic question actually: How do I switch between views on the iPhone?
I don't want to use a tab bar controller or navigation controller. Tapping a button on one screen (view) should bring the user to another screen. Possibly I want to have a nice transition animation, like a flip or a sliding animation.
Right now I'm just adding multiple views to the window and I just view / hide them according to what I want to show. It seems to be ineffective. I would much rather have a stack or something, so that only views that are currently displayed are loaded into memory. Also, I don't want to worry about hiding views that are not shown. Something like switchToView:viewXYZ would be much rather preferred. Is that even possible. Maybe with a view controller? There must be a way, right? I don't thing I'm supposed to just hide / show views.
Thank you very much!

Interesting.. I have been using the UIView animation for changing views, but had not figured out yet how to push a view right or left.. however, when I try this, it does not work as expected. The push works, but the new view also "fades" in while pushing.. instead of a clean push.. any thoughts?
Here is the code...
CATransition* trans = [CATransition animation];
[trans setType:kCATransitionPush];
[trans setDuration:0.5];
[trans setSubtype:kCATransitionFromBottom];
... code to change the view...
CALayer *layer = rootViewController.view.layer;
[layer addAnimation:trans forKey:@"Transition"];
also tried :
[trans setType:kCATransitionMoveIn];
I have only tried this on the simulator.. I guess I should try it on the device. as I have noticed other animations do not display properly on the simulator (for example, CurlUp does a dissolve... in the sim but works on the device..) I will update when I test it.
thanks!
