Answer 1

If you must include the code detection in your uiimageview subclass then I would tell the appdelegate that a touch was received and where. The app delegate could then either tell all your uiimageviews or tell the viewcontroller which would tell it's uiimageviews.

untested code:

appDelegate = (myAppDelegate *)[[UIApplication sharedApplication] delegate];
[appDelegate touchedAt:(int)xPos yPos:(int)yPos];
