title: page curl effect to transit between classes in iphone
body: <p>i am working with page curling effect .on click of a button i was able to transit the page(i.e between the UIViews).the following code depicts the same</p>
  
  <pre><code>UIView beginAnimations:nil context:NULL];
      [UIView setAnimationDuration:1.5];  
      if ([sender tag] == 1) {
          [UIView setAnimationTransition:UIViewAnimationTransitionCurlDown forView:placeholder cache:YES];
      }
      else {
          [UIView setAnimationTransition:UIViewAnimationTransitionCurlUp forView:placeholder cache:YES];
      }
      if (view1OnTop) {
          [view1 removeFromSuperview];
          [placeholder addSubview:view2];
      }
      else {
          [view2 removeFromSuperview];
          [placeholder addSubview:view1];
      }
      [UIView commitAnimations];
  
      view1OnTop = !view1OnTop;
  </code></pre>
  
  <p>with this i was able to curl between UIViews ,but my question is , will i be able to apply this kind of transition between two or more classes???
   thanks in advance</p>
