The goal here is to consider changes in the layer content, what isn't possible with the provided CA properties (are closely tied with OpenGL operations) : either the content changes aren't notified, or the animation calculation will be triggered too often (unnecessarily, because forced), leading to poor performance. A link to the source code is provided.
We could also find at Theocacao an article that explains why Core Animation principle (implicit programming using KVO) isn't restricted to animating. That is exactly what I thought two years ago, and I've planned since that time to use this approach in web frameworks. | | | Comments | | Write a comment | |
