Question

in ios 5 i was able to disable the double tap zoom by just overriding it with a new double tap gesture. But it seems that the double tap gesture is no longer in the gesturerecognizer array that comes with the mkmapview.

NSArray *gestureRecognizers = [_mapView gestureRecognizers];
for (UIGestureRecognizer *recognizer in gestureRecognizers) {
    NSLog(@"%@", recognizer);
}

returns nothing in ios 6, where in ios 5 it would return 2 recognizers, one for single tap and one for double tap.

Answer 1

I’d look through the gesture recognizers of MKMapView’s subviews. It’s probably still there somewhere.

Of course, messing around with another view’s GRs is slightly dubious and will likely break the next time Apple changes something about MKMapView…

EDIT: For the benefit of anyone else reading this, please check that it’s a UITapGestureRecognizer and that numberOfTapsRequired == 2 and numberOfTouchesRequired == 1.

Also, instead of disabling double-taps on the map entirely, consider adding a double-tap GR on the annotation and then do [mapDoubleTapGR requireGestureRecognizerToFail:annotationDoubleTapGR]. Again, hacky — don’t blame me if it breaks on the next OS update!
