i'm very new to core animation. i'd like to know if you can do simple motion/shape tweening like in Flash, or is it all only a frame by frame array of static images? for example: can i produce an animation by only having an array of 2 images: a circle and a square. using start coordinates for the circle, end coordinates for the square and a timer, create a animation of the circle moving across the screen while morphing (or blending) into the square? if so, that would be amazing.
