我可能会继承UIImageView并覆盖touchesEnded：withEvent：

- (void)touchesEnded:(NSSet *)touches withEvent:(UIEvent *)event
{
    // ignore if more than one finger
    if ([touches count] != 1) {
        [self.nextResponder touchesEnded:touches withEvent:event];
        return;
    }

    UITouch *touch = [touches anyObject]; // there's only one object in the set

    // ignore unless the user lifted the finger off the screen
    if (touch.phase != UITouchPhaseEnded) {
        [self.nextResponder touchesEnded:touches withEvent:event];
        return;
    }

    // ignore if double-touch or more
    if ([touch tapCount] != 1) {
        [self.nextResponder touchesEnded:touches withEvent:event];
        return;
    }

    CGPoint locationOfTouch = [touch locationInView:self];

    // TODO: use locationOfTouch.x and locationOfTouch.y to determine which part has been selected
}
