如何使MGLPolyline渐开线? [英] How to make a MGLPolyline tapable?

问题描述

我目前正在寻找一种使路线(MGPLPolyline)可点击的方式，以便用户可以在Mapbox下的两条可能的路线之间进行选择.不幸的是，路由注释似乎根本无法被点击:

I am currently looking for a way to make a route (MGPLPolyline) tappable such that a user can choose between two possible routes under Mapbox. Unfortunately the route annotation doesn't seem to be tappable at all:

虽然我已经正确设置了MGLMapViewDelegate这种方法:

While i have properly set my MGLMapViewDelegate this method:

func mapView(_ mapView: MGLMapView, didSelect annotation: MGLAnnotation)

永远不会被调用.

我想知道每行都是从MGLPolyline继承而来的，这是MGLAnnotation的子类(我希望它可以被点击...).

What did i miss knowing that each line inherited from MGLPolyline which is a subclass of an MGLAnnotation (which i was expected to be tappable...).
