Instagram has a really cool interaction where you can click and hold, just like a longPress, image, and an interactive popup appears. Once it appears, you can drag your finger to one of the action buttons, and removing the finger applies the action and closes the pop-up window.
Here it is in action. And here is a link to the video if you need to take a closer look.

In my application, a popup window with touch and hold works, but dragging a finger continues to control the main view.
How do you get finger interaction to go to the popup?
How do you get drag-and-drop buttons?
