"self' is my circle object. I forgot to mention that I move the circles around onscreen, so the text would ideally somehow be embedded within the circle objects so they could track together. Would it make sense to have a parallel CATextLayer associated with each CALayer in my circle object? Or does CAShapeLayer have that capability?

I'd like to label them. What is 'self' in the code above? Having the delegate draw the text would be the simplest thing you can do. Next simplest would be to add a CATextLayer sublayer. At a higher level however, you could do the exact same thing with UIViews and use UILabel for your labels (which since they do less work for text layout are generally faster). -- David Duncan _______________________________________________ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.
