A CALayer itself is not associated with a context. The NSView owns the graphics context.

Actually when your in layer backing mode, the CALayer owns the graphics context.

The context you are looking for is passed to the "drawLayer:inContext" message.

This is true, and covered well in the Core Animation Programming Guide <http://developer.apple.com/documentation/Cocoa/Conceptual/CoreAnimation_guide/Introduction/Introduction.html >

Specifically, the section on Providing Layer Content.
