iOS:Swift-如何在触摸屏上添加精确的地图并获取该位置的详细地址? [英] iOS : Swift - How to add pinpoint to map on touch and get detailed address of that location?

问题描述

我想在触摸iOS地图时添加注释，并获取各个位置的详细地址(地标).如何在Swift中实现这一目标?

I want to add annotation on touch of iOS map and fetch the detailed address (Placemark) of respective location. How I can achieve this in Swift?

提前谢谢.

推荐答案

要对地图的触摸做出反应，您需要为mapView设置一个点击识别器

To react to the touch on map you need to set up a tap recogniser for the mapView

在 viewDidLoad 中:

let gestureRecognizer = UITapGestureRecognizer(target: self, action:"handleTap:")
    gestureRecognizer.delegate = self
    mapView.addGestureRecognizer(gestureRecognizer)

处理水龙头并获得被点击的位置坐标:

Handle the tap and get the tapped location coordinates:

func handleTap(gestureRecognizer: UILongPressGestureRecognizer) {
    
    let location = gestureRecognizer.location(in: mapView)
    let coordinate = mapView.convert(location, toCoordinateFrom: mapView)
    
    // Add annotation:
    let annotation = MKPointAnnotation()
    annotation.coordinate = coordinate
    mapView.addAnnotation(annotation)
}

现在，您只需要实现MKMapView委托函数即可绘制注释.一个简单的Google搜索应该可以为您提供其余的服务.

Now you only have to implement the MKMapView delegate functions to draw the annotations. A simple google search should get you the rest of that.
