Add a sublayer to a CALayer without animation?

Question

How can I add a sublayer to a CALayer without animation? Usually when you add one it "fades in" and when you remove one it "fades out".

How to supress the animation?

Answer 1

Have you tried this:

[CATransaction begin];
[CATransaction setValue:(id)kCFBooleanTrue
                 forKey:kCATransactionDisableActions];
[layer addSublayer:sublayer];
[CATransaction commit];

from the Apple docs?
