How to disable CALayer implicit animations?

Question

It's driving me crazy! I am working on a drawing application. Let's say I am working on a UIView called sheet.

I am adding some sublayers to this view ([sheet.layer addSublayer:...]) and then I want to draw into them. To do so I am creating a CGImageRef and putting it into the layer's contents. But it's animated and I don't want that.

I tried everything:

• removeAnimationForKey:
• removeAllAnimations
• set the actions dictionary
• using the actionlayer delegate
• [CATransaction setDisableAnimations:YES]

It's seems correct. I don't understand why this layer is still animated ;_;
Am I doing something wrong? Is there a secret way?

Answer 1

Swift

CATransaction.begin() CATransaction.setDisableActions(true)  // change layer properties that you don't want to animate  CATransaction.commit()
