Not so long ago, tried to use the image format .svg provided by the designer. After a couple of hours pounding it was decided to make a few pictures in the format .png with a size corresponding to the Apple guidelines. Threw and started to use within 3 minutes.
So in the case of iOS by far .png the best choice.

(no resizing, coloring and the like in runtime)
