After rotating a CALayer using CABasicAnimation the layer jumps back to it's unrotated position

Question

I am trying to create a falling coin. The coin image is a CALayer with 2 CABasicAnimations on it - a falling down and a rotation one. When the falling down animation gets to

Answer 1

I was trying to rotate an arrow back and forth, like the Twitter/Facebook "Pull to Refresh" effect.

The problem is, I was doing the rotation back and forth on the same UIView, so after adding

rotation.removedOnCompletion = NO;
rotation.fillMode = kCAFillModeForwards;

The forward animation war working OK but the backwards animation was not working at all.

So I added the last line suggested by yeahdixon, and in addition set the view's transform to the animation's completed state: (rotation by 180 degrees)

[myview.layer removeAllAnimations];
myView.transform = CGAffineTransformMakeRotation(M_PI);

For the 'restore' animation (backwards) I do this on completion:

myView.transform = CGAffineTransformMakeRotation(0);

...and it works fine. Somehow it doesn't need the removeAllAnimations call.
