Thanks very much for the code. I have some questions though. If I'm adding a second view, I noticed after going to the second view and going back to the root view, the screen goes white. I can only see it after deleting the line "[currentView removeFromSuperview];".

What I like to know, since the mainview is the rootview, is it necessary to remove it from view. How does this effect the memory?

And if I have to remove it from the root view, should I insert the same code on the 2nd view? As in adding a new subview? How would this effect the performance?

Hope this makes sense.

//1. Add the QuatzCore Framework from library to the Frameworks folder

#import <QuartzCore/QuartzCore.h>

//3. Implement the code

yourViewController = [[YourViewController alloc]
initWithNibName:@"YourViewController"
bundle:nil];
// get the view that's currently showing
UIView *currentView = self.view;
// get the the underlying UIWindow, or the view containing the current view
UIView *theWindow = [currentView superview];

UIView *newView = yourViewController.view;

// remove the current view and replace with myView1
[currentView removeFromSuperview];
[theWindow addSubview:newView];

// set up an animation for the transition between the views
CATransition *animation = [CATransition animation];
[animation setDuration:0.5];
[animation setType:kCATransitionPush];
[animation setSubtype:kCATransitionFromRight];
[animation setTimingFunction:[CAMediaTimingFunction functionWithName:kCAMediaTimingFunctionEaseInEaseO ut]];

[[theWindow layer] addAnimation:animation forKey:@"SwitchToView1"];
