-drawInContext: is too early to stop the creation of the animation, as it occurs after -drawInContext: finishes and the layer's contents are set. You need to override -actionForKey:, watch for the @"contents" key, and return nil. There are actually lots of ways to do this so I highly recommend you read the documentation for that action, as the other methods may be useful in other contexts.


Thank you so much. That worked.

An observation. CAOpenGLLayer provides for manually controlling animations. CALayer uses automatic animations. Why the difference?
