Support animating custom layer properties #211

Closed GoogleCodeExporter closed 8 years ago

GoogleCodeExporter commented 8 years ago 
The user should be able to animate custom layer properties such as the radius 
of a pie chart. Core Animation added support for this in iOS 3.0 and MacOS 
10.6. We won't be able to support this feature in MacOS 10.5.

Enabling animation support for a property requires the following steps:

1. Implement -initWithLayer: in CPLayer and all subclasses to copy all of the 
instance variables so they will be available to the drawing methods during an 
animation.

2. Implement +needsDisplayForKey: and return YES for each key that should 
support animation. This method is only supported in iOS 3.0 and MacOS 10.6.

Step 1 is complete.
