+ Adding your own gesture recognizer to `MGLMapView` will block the corresponding
+ gesture recognizer built into `MGLMapView`. To avoid conflicts, define which
+ gesture takes precedence. For example, you can create your own
+ `UITapGestureRecognizer` that will be invoked only if the default `MGLMapView`
+ tap gesture fails:
+ 
+ ```swift
+ let mapTapGestureRecognizer = UITapGestureRecognizer(target: self, action: #selector(myCustomFunction))
+ for recognizer in mapView.gestureRecognizers! where recognizer is UITapGestureRecognizer {
+     mapTapGestureRecognizer.require(toFail: recognizer)
+ }
+ mapView.addGestureRecognizer(mapTapGestureRecognizer)
+ ```
+ 
  @note You are responsible for getting permission to use the map data and for
  ensuring that your use adheres to the relevant terms of use.
