Example of [CATransaction unlock].
In your touch handling method, wrap the animations in a transaction and lock:
[CATransaction lock];
[CATransaction begin];
// update the sublayers with new animations
[CATransaction commit];
[CATransaction unlock];
[CATransaction lock];
[CATransaction begin];
// update the sublayers with new animations
[CATransaction commit];
[CATransaction unlock];
CATransaction unlock example.
CGPathRef newPath = CGPathCreateWithRect(aLayer.frame, nil);
[CATransaction lock];
[CATransaction begin];
[CATransaction setAnimationDuration:5.0f];
CABasicAnimation *ba = [CABasicAnimation animationWithKeyPath:@"path"];
ba.autoreverses = YES;
ba.fillMode = kCAFillModeForwards;
ba.repeatCount = HUGE_VALF;
ba.fromValue = (id)aLayer.path;
ba.toValue = (__bridge id)newPath;
[aLayer addAnimation:ba forKey:@"animatePath"];
[CATransaction commit];
[CATransaction unlock];
[CATransaction lock];
[CATransaction begin];
[CATransaction setAnimationDuration:5.0f];
CABasicAnimation *ba = [CABasicAnimation animationWithKeyPath:@"path"];
