Here’s an interesting component from Simon called SnapSwift inspired by Google’s SnapSeed application allowing you to easily create pop-up menus and the ability to adjust the values within the popup menu using a panning gesture.

Here’s a video showing SnapSeed in action:
You can find SnapSwift on Github here.
You can read more about SnapSwift on the FlexMonkey blog.
