Using a sublayer for this purpose is I think the best solution for your issue. Just create a CATextLayer and add it as a sublayer and your set.

Would it make sense to have a parallel CATextLayer associated with each CALayer in my circle object? Or does CAShapeLayer have that capability?

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).
