Double-Tap Alternative

Instead of implementing the long-tap gesture menu provided by UICollectionView, Recipe 10-9 creates a custom cell class and adds a double-tap gesture recognizer. When activated, the callback sets the cell as the first responder and presents a standard menu.

Recipe 10-9 shows the relevant details. The cell subclass declares that it can become the first responder, a necessary precondition for presenting menus. It sets the menu items it wants to work with and then adds the canPerformAction:withSender: support that confirms each item’s appearance. Figure 10-10 displays the menu created by this code.
