title: Add Actionsheet in UITabbarcontroller in iOS
body: <p>I created UITabbar in UIViewController. Then i added a UIActionSheet to it but when the actionsheet appeared, when top part of button "Cancel" is clicked, it works, but when I click the bottom part of "Cancel", there's no response. I used this code to add the actionsheet:</p>
  
  <pre><code>actionSheetDelete = [[UIActionSheet alloc] initWithTitle:@"Do you want to continue?" delegate:self cancelButtonTitle:@"Cancel" destructiveButtonTitle:@"Delete Item(s)" otherButtonTitles:nil];
  actionSheetDelete.actionSheetStyle = UIActionSheetStyleBlackOpaque;
  [actionSheetDelete showInView:self.view];
  [actionSheetDelete release];
  </code></pre>
  
  <p>When i click on action sheet, i always show this alarm in console:</p>
  
  <pre><code>Presenting action sheet clipped by its superview. Some controls might not respond to touches. On iPhone try -[UIActionSheet showFromTabBar:] or -[UIActionSheet showFromToolbar:] instead of -[UIActionSheet showInView:].
  </code></pre>
  
  <p>Do you have any suggestion? Thanks in advance</p>
