Create custom activity indicator in iPhone SDK?

Question

I haven't found any references to apps that use a custom activity indicator -- would be an animated GIF old-school -- in place of the Apple-supplied spinning wheels. Are there facilities to do this (or subclass UIActivityIndicatorView), do developers roll their own UIViews, or does this violate HIG?

Thanks, IPD

Answer 1

The UIImageView class supports animation. Try that.

Answer 2

Or you can use an animation to rotate the layer. Here is an interesting post about how to do that :

Hope this helps.

Answer 3

Yeah, as Ed Marty mentioned UIImageView supports the animation of images. So look at this custom activity indicator tutorial to get an inspiration how you could achive this in a very simple way.
