It's not merely a convenience. We live in an age of blocks; we want the block-based approach to replace the old delegate-based approach. One is not merely a convenient form of the other; they are fundamentally different architectures. For true layer animation (as opposed to view animation) this *is* the block-based approach. Apple did not give a CAAnimation a completion block property, so you *have* to use CATransaction to get one. m.
