Creating the Iphone MapKit showUserLocation Ring Annimation

Anyone know how of an approach to re-create the animation that mapkit uses on the showUserLocation ? Would you do it with a series of images or a single image that is then expanded and faded out?

CALayer addSublayer increasing retain count?


My iphone application crashes
I just looked at it, and it looks a bit too complex to did with a single image and any sort of UIView animation. What is the best way to download image data from ASP.NET to iphone? I'd just bite the bullet and use a set of images for it -- the total footprint can't be very much. Performance problems on iPhone using simple graphics . Converting OpenGL Primitives to OpenGLES It's a beautiful animation though, isn't it?. EXC_BAD_ACCESS error

Not sure how Apple does it exactly although I know they're using 3 differently sized images for their halo animation. Probably for the reason this scaling the largest image to a small size would result in artifacts..
