After Animation, View position resets

Question

Might want to set these properties. They cause the presentation to be preserved at the end of the animation.

animation.fillMode = kCAFillModeForwards;
animation.removedOnCompletion = NO;

Then the "animationDidStop:" method can be used to remove the view at the end of the animation:

-(void) animationDidStop:(CAAnimation *) animation finished:(bool) flag {
    if (animation == [containerView.layer animationForKey:@"moveX"]) {
        // remove view here, add another view and/or start another transition
    }
}

Well, according to the Apple sample "MoveMe", this (removedOnCompletion) should work, however, it doesn't seem to.

So, add these lines after your code:

[self.view.layer  addAnimation:animation forKey:@"moveX"];
self.view.layer.position = [animation.toValue CGPointValue];

This ensures that after the animation runs, the layer is properly positioned.

I had this issue when performing several animations in an animation group. I had to set a couple properties on the animation group itself, not the individual animations.

CAAnimationGroup *animGroup = [CAAnimationGroup animation];

// MAKE SURE YOU HAVE THESE TWO LINES.
animGroup.removedOnCompletion = NO;
animGroup.fillMode = kCAFillModeForwards;

animGroup.animations = [NSArray arrayWithObjects:moveAnim, scaleAnim, nil];
animGroup.duration = tAnimationDuration;
[tImageView.layer addAnimation:animGroup forKey:nil];
