Difference between kCAFillModeRemoved in CAMediaTiming and removedOnCompletion property of CAAnimation

In apple's document, kCAFillModeRemoved in CAMediaTiming is : The receiver is removed from the presentation when the animation is completed.

removedOnCompletion property of CAAnimation is : Determines if the animation is removed from the target layer’s animations upon completion.

I know that if set removedOnCompletion to YES, the instance of CAAnimation will be removed when animation is complete. Now my question is that if set fillMode to kCAFillModeRemoved, what is removed when animation is complete.

The key word you are missing in those sentences is "presentation".

The removedOnCompletion property determines whether or not the animation object is removed from the layer upon completion.

The fillMode property determines the appearance of the presentation layer before and after the animation has passed (before beginTime and after beginTime+duration).

Example 1: removed = NO and fillMode = removed will look as if the animation is removed but it's not.

Example 2: removed = YES and fillMode = forwards the animation will be removed upon completion so there is nothing for the fill mode to fill in after the animation.
