So the jist of it is that I create a subclass of CAKeyframeAnimation
that has a sequence of images in it's values property and a sequence
of frame durations in the keyTimes property. I can then add the
animation to a layer to display and that's where the problem
arises. The first time (and only the first time) the animation is
played the first few frames don't display (the movies are short,
they only consist of 3-12 frames at 15fps) After the first time I
play the animation and it fails, I can play the animation just fine.
Please file a bug report on this issue.
One work around is to animate the contentsRect property instead of
contents and use the contentsRect to select a portion of a single
image that is assigned to the contents property of the layer.
