animation - Drag to rotate in iPhone-app -

-

I'm trying to pull a UIImageView according to an anchorpoint, but the whole image move is actually a one for my app settings The scene is and a parameter is set with the dial (hands / needle (?)). I want that when I am pulling it, the location of the needle / rotation center does not increase.

Thank you for your future reply.

You have to set a conversion rotation on your needle layer.

To see the correct sample code for you, the Metronome app that Apple provides will be very similar to you.
