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.
