Tagging CALayers in iPhone

Question

I am looking for a general way to be able to search for a unique CALayer in a hierarchy without having to remember where the layer is in a hierarchy (and use the sublayer: and superlayer: methods).

I know this is possible with UIViews (which makes flipping views easy) but is it possible for CALayer?

thank you in advance for your help

You can also use the name property of the CALayer.

[layer setName:@"myKey"];

To look it up,

- (CALayer *)myLayer {

    for (CALayer *layer in [superLayerOfMyLayer sublayers]) {

            if ([[layer name] isEqualToString:LabelLayerName]) {
                return layer;
            }
    }

    return nil;
}
