title: UIPopover on ARC
body: <p>I am using ARC on an iPad app with the code below, the popover flashes on the screen, but doesn't stay.
  What I am doing wrong?
  Please help</p>
  
  <pre><code>- (IBAction)photoLibraryAction:(id)sender
  
  {   
  
     UIImagePickerController *imagePicker = [[UIImagePickerController alloc] init];
     [imagePicker setDelegate:self];
  
     UIPopoverController *pop1 = [[UIPopoverController alloc]     initWithContentViewController:imagePicker];
      [pop1 setDelegate:self];
      [pop1 presentPopoverFromBarButtonItem:sender  permittedArrowDirections:UIPopoverArrowDirectionAny animated:YES];
      [pop1 setPopoverContentSize:CGSizeMake(320, 400)];
  }
  
  
      if  ([pop1 isPopoverVisible])
      {
          // Popover is not visible
          [pop1 dismissPopoverAnimated:YES];
  
      }
  
  }
  </code></pre>
