Overview

CAAnimationGroup allows multiple animations to be grouped and run concurrently. The grouped animations run in the time space specified by the CAAnimationGroup instance.

The duration of the grouped animations are not scaled to the duration of their CAAnimationGroup. Instead, the animations are clipped to the duration of the animation group. For example, a 10 second animation grouped within an animation group with a duration of 5 seconds will only display the first 5 seconds of the animation.

Important: The delegate and removedOnCompletion properties of animations in the animations array are currently ignored. The CAAnimationGroup delegate does receive these messages.

Note: The delegate and removedOnCompletion properties of animations in the animations property are currently ignored.
