Can I animate the UIScrollView contentOffset property via its layer?

Question

I want to zoom and scroll a UIScrollView with a CGPathRef. Because of that I assume I have to animate the UIScrollView\'s layer property? But which property would I animate th

Answer 1

Moving a CALayer around is done by (preferably) setting it's .position property - or possibly the anchorPoint (c.f. the docs on that: http://developer.apple.com/library/ios/#documentation/GraphicsImaging/Reference/CALayer_class/Introduction/Introduction.html ).

...but I don't think you want to mess with the CALayer if you're working with a UIScrollView. Have you tried applying plain CoreAnimations to your ScrollView?

(the problem is: the UIScrollView is implemented on top of CALayer - so even if you can hack it to work today, it's quite likely to break in future iOS versions. If possible, you want to avoid the CALayer for that particular class)
