I have a structure composed on a root layer and 2 CALayer subclass. These 2 layers contain a layer too. 

Here a scheme: 

```
ROOT LAYER 
    |
    |------- LAYER A
    |           |---------BG
    |
    |
    |--------LAYER B
                |---------BG

```

If I call the `hitTest` method on the `ROOT LAYER` it returns the most inner layer into the hierarchy. So if user clicks over `LAYER A` I get the `BG` of `LAYER A`. 

```
//In this example hitResult will contains the BG of LAYER A or the BG of LAYER B
CALayer *hitResult = [rootLayer hitTest:point)]; 

```

How can I stop the responder chain and get directly `LAYER A` or `LAYER B` from a HitTest sent to `ROOT LAYER` ?
