What is the full Keypath list for CABasicAnimation?

Question

I've looked in the documentation but I noticed it's missing some like "transform.scale.xy": [CoreAnimation Guide][1] is there a more complete list?

Answer 1

Here's everything I'm aware of in terms of animatable properties, keyPaths, and key-value coding extensions.

CALayer Animatable layer properties -- the other CALayer types below all inherit from CALayer, so these also apply to those:

anchorPoint backgroundColor backgroundFilters borderColor borderWidth bounds compositingFilter contents contentsRect cornerRadius doubleSided filters frame hidden mask masksToBounds opacity position shadowColor shadowOffset shadowOpacity shadowPath shadowRadius sublayers sublayerTransform transform zPosition 

CAEmitterLayer animatable properties:

emitterPosition emitterZPosition emitterSize 

CAGradientLayer animatable properties:

colors locations endPoint startPoint 

CAReplicatorLayer animatable properties:

instanceDelay instanceTransform instanceRedOffset instanceGreenOffset instanceBlueOffset instanceAlphaOffset 

CAShapeLayer animatable properties:

fillColor lineDashPhase lineWidth miterLimit strokeColor strokeStart strokeEnd 

CATextLayer animatable properties:

fontSize foregroundColor 

CATiledLayer animatable properties:

I feel like tileSize is animatable, but documentation doesn't agree. 

CATransform3D Key-Value Coding Extensions:

rotation.x rotation.y rotation.z rotation scale.x scale.y scale.z scale translation.x translation.y translation.z 

CGPoint keyPaths:

x y 

CGSize keyPaths:

width height 

CGRect keyPaths:

origin origin.x origin.y size size.width size.height 

These are Appendix B of the Core Animation Programming Guide, and Appendix C of the same.
