But, not to beat a dead horse or anything, the Core Animation-related stuff in the docs needs much more than this, namely a complete overhaul. Considering how wonderfully the docs have improved in recent years, it's a bit sad how this area, which has become crucial with the advent of iOS, has lagged. I've pointed out many failings in earlier notes to this list (the discussion of actions and their keys and the search for them is wrong and incoherent, etc.). In general the docs on animation suffer from coyness; they hint demurely rather than just stating the facts developers need to know. I have discovered (by painful and rather boring testing) key facts about core animation that have made it simple, easy, and crystal clear to me, but that are nowhere explained in the docs, even though a simple sentence would suffice (in particular, a few tiny additions to the documentation on addAnimation:forKey: would prevent hours of developer time lost). Also I would recommend that the docs on layers be separated from those on animation, because despite the CA prefix and the fact that (obviously) layers are what gets animated, layers themselves have great importance quite outside the realm of animation, so readers who *just* want to know about layers should not have to wade through the animation stuff to discover the facts. m. >On Sep 20, 2010, at 7:24 PM, Kenneth Baxter wrote: > >> Brilliant!

Your not supposed to @synthesize these properties. Unless you let Core Animation define them (by declaring them @dynamic) they cannot be animated and you will see the symptoms you see. In your -drawInContext: method you can then query the property to get the current value. >> -- >> David Duncan -- matt neuburg, phd = m...@tidbits.com, <http://www.tidbits.com/matt/> A fool + a tool + an autorelease pool = cool!
