MKMapView and the responder chain - objective-c

Question

I have an MKMapView with a single subview:
MKMapView *mapView = [[MKMapView alloc] initWithFrame:[UIScreen mainScreen].bounds];
UIView *subView = [[UIView alloc] initWithFrame:CGRectMake(0, 200, 200, 200)];
subView.backgroundColor = [UIColor grayColor];
[mapView addSubview:subView];
I would expect that because the subview does not handle any touch events, all touch events would be passed along to the parent map view (via the responder chain). I would then expect that panning and pinching in the subview would pan and pinch the map.
This, unfortunately, does not appear to be the case. Does anyone know of a way to get the map view in to the responder chain?
I realize overriding hitTest in my subview can achieve what I'm expecting here, but I can't use that approach because I have other gestures I need to respond to in the subview.

How about handling all gestures with UIGestureRecognizers (properly setup to ignore other gesture recognizer or to fire simultanously with them) added to your mapView and disabling userInteractionEnabled of your subview?
I use the following code to listen to Taps on the mapView without interfering with the standard gestures:
UITapGestureRecognizer *tap = [[UITapGestureRecognizer alloc] initWithTarget:self action:#selector(mtd_handleMapTap:)];
// we require all gesture recognizer except other single-tap gesture recognizers to fail
for (UIGestureRecognizer *gesture in self.gestureRecognizers) {
if ([gesture isKindOfClass:[UITapGestureRecognizer class]]) {
UITapGestureRecognizer *systemTap = (UITapGestureRecognizer *)gesture;
if (systemTap.numberOfTapsRequired > 1) {
[tap requireGestureRecognizerToFail:systemTap];
}
} else {
[tap requireGestureRecognizerToFail:gesture];
}
}
- (void)mtd_handleMapTap:(UITapGestureRecognizer *)tap {
if ((tap.state & UIGestureRecognizerStateRecognized) == UIGestureRecognizerStateRecognized) {
// Get view frame rect in the mapView's coordinate system
CGRect viewFrameInMapView = [self.mySubview.superview convertRect:self.mySubview.frame toView:self.mapView];
// Get touch point in the mapView's coordinate system
CGPoint point = [tap locationInView:self.mapView];
// Check if the touch is within the view bounds
if (CGRectContainsPoint(viewFrameInMapView, point)) {
// tap was on mySubview
}
}
}
