What kind of value is keyTime in an CAKeyFrameAnimation?

Question

For example I have this CAKeyFrameAnimation:

CALayer* theLayer = myView.layer;
    CAKeyframeAnimation* animation;
    animation = [CAKeyframeAnimation animation         


        

Answer 1

The value of keyTimes is a percent of the total duration. Valid values range between 0 and 1 (0% to 100%). Your last value of 1.6 is invalid.

As an example, if a keyframe is supposed to happen 0.8 seconds into the animation that keyTime would be 0.5 given your duration of 1.6 seconds.
