title: Implement Long press on button and show delete button on top of that button like deleting app from background
body: <p>I want to implement a long press on my button and after that long press a cross button should appear on the top of the button to remove that button from scroll view which is added in table view.</p>
  
  <p>I search on web and got <code>UILongPressGestureRecognizer</code> to implement.I tried with it but I have many button in my scroll view and I put <code>UILongPressGestureRecognizer</code> on every button but how will I give reference of the pressed button to the selector method so that I can add a cross button on that particular pressed button.</p>
  
  <pre><code>UILongPressGestureRecognizer *longPressGesture = [[UILongPressGestureRecognizer alloc] initWithTarget:self action:@selector(deleteAppFromList:)];
  UIButton *btn=(UIButton *)[cell.contentView viewWithTag:101+i];
  [btn addGestureRecognizer:longPressGesture];
  [longPressGesture release];
  </code></pre>
  
  <p>Please suggest me how to implement this.I want to do the functionality just as when we delete an app from ios device or simulator.</p>
