hi, i’have a calayer subclass that draw a circle overriding the drawInContext method. I want to remove this layer using a radial wipe transition. Right now i have done this using a rectangle mask over the circle and then rotating the mask. The problem is that i have some drawing errors. Is there a better way of doing this?
Not on the iPhone, unfortunately. However on the mac you can use a CIFilter to do just about anything you want with the transition.
Thank for your reply Bill, now my question is: is there any CIFilter that makes this kind of transtion or i have to build my own CIFilter?
Not sure, check out the Core Image Fun house to see the list.
