I've been doing iOS long enough now that my Mac OS is rusty. Sad but true.
I'm back doing some Mac development, and animation is a lot harder.
There's no view-based animation like there is in iOS, and I miss it. For quick-and dirty animation, the UIView animateWithDuration:animations: block-based animation calls are hard to beat.
So, drop back and punt. I've set "needsLayer" to true for several NSView objects.
Then I try to create a CABasicAnimation to grow my view from small to large.
Just like in iOS, the docs say that the center of a layer is it's anchorPoint, which defaults to .5, .5 (the center of the layer.) However, when I create a transform animation that animates my view's backing layer from a point (scale to .001, .001, 1) up to the identity matrix, it grows from the lower left corner (0,0) instead.
I have to set the anchorPoint to .5,.5 manually, and then I have to shift the position of the layer to half-width, half-height to compensate.
What am I missing?
