remove every type of subview from uiscrollview?

hello all i am using this code to show flip animation...... i have a uiview with scrollview(paging enabled)...so it shows a view like a page...now i also have done flip animation using this code....

-(void)flipView {     flashCardAnswerController *flashCardAnswerControllerobj =  [[flashCardAnswerController alloc] initWithNibName:@"FlashCardAnswerView" bundle:[NSBundle mainBundle]]; [flashCardAnswerControllerobj.view setFrame:[[self view] frame]]; [UIView beginAnimations:nil context:nil]; [UIView setAnimationDuration:0.60];// Sub. duration   UIView *superview;      if ((superview = [[self view] superview])) { 	[UIView setAnimationTransition:UIViewAnimationTransitionFlipFromLeft   forView:superview cache:YES]; 	[superview addSubview:[flashCardAnswerControllerobj view]]; } [UIView commitAnimations]; } 

so according to code the new view will be added to scrollview..i also manage to release the new view while flipping back...but if i directly push the back button on navigaion controller...the flip side view won't release. i tried this in dealloc method of my scrolleview's class but it doesn't work

for(UIView *subview in [scrollView subviews]) { 	    [subview removeFromSuperview]; } 

how do i remove flipside's view the views are very much in number...approx. 48 plus 48 flip side views so definietly it will create memory issues on device...

also could someone tell me a way to disable NavigationBar's back button in flip side view...without creating scolling class's object.

I do not have a direct answer to your question, but I can tell that this is the old iPhone OS 2.x way of displaying a views flip-side..

In iPhone OS 3.0 you should use presentModalViewController:animated: instead.

This is much less code, and all of the problems you describe in your questions goes away..
Is NSTimer auto retained?
The idea is that the flip-side of the current view, is managed by a separate UIViewController that you display modally.

But in addition to the sliding animation from 2.0 you can also have the new view controller animate in and out with a horizontal flip..
Why does this create a memory leak (iPhone)?
self.modalTransitionStyle = UIModalTransitionStyleFlipHorizontal; [self presentModalViewController:flipSideController                         animated:YES];
