Gestures and the defendant chain

I am developing an ipad application. And I have scroll appearance and inner scroll. Inside im's internal scroll list, a grid is used to render my items. Im using a library for this called GMGridView.

and in the form of a grid im using gestures. (for example: a gesture of movement). Grids are added as representations to the scroll view. So, if my understanding of the responder chain is correct, the super-view should respond first, and then the subzones. But now wat happens when i touch the gridview, the control immediately goes to gridview.

Any idea why this is happening? Basically, what I want to do is scroll the appearance, which needs to be scrolled before the control moves to the internal scroll view, which is a vertical scroll view.

It will be great if someone can help me. Thanks in advance.
