Question

Specs: about 320 x 270 px, 5 seconds. I don’t know exactly how many images needed for a fluid animation, but let’s assume 30.

What would be the best way to playback this? As a movie file in some kind of quicktime view (if available), or as an animated image sequence with UIImageView? I’m not sure but I believe loading 30 images per second is nearby impossible on the ipod touch. Any idea?

Answer 1

Why would you not want to use a video file? If you don’t have very specific reasons, I would recommend just using the standard video playback functions provided by Apple.

This gives you several advantages:

• Even if your proposed method would run fluidly, it certainly wouldn’t be as well optimised for the graphics chip and therefore use up more battery
• It’s very easy to implement, whereas your idea would be rather complicated, and you’d spend a lot of time on a probably less important part of your app.
• It’s won’t introduce any new bugs and is most likely a lot better tested than your custom solution.
