Disable animation when moving CALayers

Question

The following code animates the movement, even though I didn\'t use beginAnimations:context. How do I get it to move without animating? This is a new iphone vi

Answer 1

The simplest way to do it is to override the animation duration by putting the position code into a transaction:

- (void)touchesMoved:(NSSet *)touches withEvent:(UIEvent *)event {
    [CATransaction begin];
    [CATransaction setAnimationDuration:0];
    sublayer.position = [[touches anyObject] locationInView:self.view];
    [CATransaction commit];
}

Answer 2

More simplest way:

sublayer.position = [[touches anyObject] locationInView:self.view];
[sublayer removeAnimationForKey:@"position"];
