Gesture that spans multiple views and "delegates to sub-views"?

[dcorbin]

I am developing something that requires a non-standard/generic gesture that covers multiple views. Think about something similar to a swipe-keyboard where each key is a sub-view. One touch down, a lot of finger movement, and. touch-up

I'm pretty confident I can make Pan Gesture at higher levels, and if I know where views are laid-out, I can manage it all in the gesture recognizer. I may do this if there's not a better way.

I'm hoping there's a way to have the main gesture handler delegate touch-events to the views/sub-components and they in turn might trigger events and/or state changes. The closest I have here is to create a gesture-subview-handler that maps to the each actual laid-out view (and know the layouts), and have event delegated to them if appropriate. This involves keep parallel heirarchies keeping them up-to-date with regards to layout. Not pretty in my book.

Is there a pattern or better approach to this that I'm missing?
Thanks
