how to disable parent view's user interaction - iPad

Question

Hello All,

I have added a sub view on the screen. Now I want to disable the parent view's user interation. But when i do this using -

GenreShelfViewController *gsvc = (GenreShelfViewController *) parent;
[gsvc.view setUserInteractionEnabled:FALSE];
[gsvc release];

(I am doing this in subview's viewDidLoad method)

Sub view also freezes up and not responding to interations.

Any other idea?

Thanks
