I'd like to create an animation that starts with the appearance of a small circle then progresses like this:
- 2nd larger circle appears
- 3rd larger circle appears
- 1st smallest circle disappears
- 4 larger circle appears
- 2nd circle disappears
and on to probably six or so circles.
Circles will fades in/out. Each larger circle encloses the smaller circle before it. This is the same type of animation you might see in instructional screencast. The instructor clicks something and where the click occurs, there is an animation that speads out and fades as circles get wider. Similar to dropping a pebble into a pond.
I could probably do this with several UIImageViews and a timer. But is there a better way?
