I used CGPath to make a picture with 4 CALayers, how can I zoom in and out?

Question

The picture contained a four different circles, a rectangle, and a more complicated shape.However, I want to make it zoom in and out like UIRefreshControl. It's unrealistic to control every shape at the same time to make it look like the original.

dont get it. put it in a scrollview – Daij-Djan Mar 14 '13 at 09:27 — Daij-Djan, Mar 14 '13 at 09:27

If you need it: in your drawInRect: method you can add CGContextScaleCTM (yourContext,scaleX,scaleY); when scaleX and scaleY are CGFloat. Experiment with it. For example you can set scale with a UISlider.
