IOS button animation search

Question

Any ios user control that does something like a volume button with a ticker. I want to use this as a menu selection tool in my project, as soon as I saw such a control, but forgot. Any help is greatly appreciated.

Or, if someone saw the number lock animation in iOS, that would be nice too. Something like the image below. I am going to use this for a menu.

You can do this using a progress bar. Below are links to help you do this:

Answer 2

Check out NDRotator on Cocoa Controls. It looks like it's a rotary knob that does what you want. You just need to adapt it to use the image as a pen instead of the hand-drawn graphics that it currently uses.

You may have to add a tick sound yourself.
