Disable DoubleTapGesture Zoom out on MKMapView

I have observed MKMapView zoom-out on Double tap gesture, I didn't find any way to disable it. I tried to add own Double Tap Gesture to catch Double tap action but it still zoom out. Any thought?

Solution

There is no API to disable or change double-tap behavior with MKMapView.

But, if you really want to do so, one approach would be to find and remove the double-tap gesture recognizer from the MKMapView object.

In the project you shared, you could do that in makeUIView in your UIMapView class:

func makeUIView(context: UIViewRepresentableContext<UIMapView>) -> UIViewType {
    self.configureView(mapView, context: context)
    setRegion(to: palce)
    
    if let v = mapView.subviews.first,
       let ga1 = v.gestureRecognizers
    {
        let ga2: [UITapGestureRecognizer] = ga1.compactMap { $0 as? UITapGestureRecognizer } .filter { ($0.numberOfTapsRequired == 2) }
        for g in ga2 {
            v.removeGestureRecognizer(g)
        }
    }

    return mapView
}

I wouldn't necessarily suggest that you do so, however.

Apple may change the MKMapView object in the future, which could then break this.
User's tend to prefer that common UI elements behave in expected ways.

Personally, I get rather annoyed when using an app and the developer has changed standard functionality of UI elements. For example, if I see a table view row with a disclosure indicator (the right-arrow / chevron), I expect that tapping the row will "push" to another screen related to that row. I've seen apps that do not follow that pattern, and it just gets confusing.
