Good question. One problem is that I have not understood a fundamental property of Core Animation. I have always assumed that the animation, once I have set it up, is done by the OS / Core Animation in the background, i.e., in a separate thread. Is that correct? If yes, then wouldn't that mean that moving my image loading into a separate thread would *not* help at all? If no, then exactly when / where is the animation performed? You see, my understanding of the interplay between Core Animation and my application is still a mess ;-} So any light anybody can shed on it will be highly appreciated. > Image loading would be the first thing I would move into a background thread. > Can you use GCD? It’s a perfect fit for such producer/consumer tasks. Please explain "GCD". Thanks a lot in advance. Best regards, Gabriel.
