Question

当用户移动地图时，会调用以下函数。

可以获取视口吗？视口是北/东和纬度的经度和纬度。和lon。南/西。

 func mapView(mapView: MKMapView, regionDidChangeAnimated animated: Bool){
    print("The \(mapView.centerCoordinate)")
    print("the maprect \(mapView.visibleMapRect.origin)")
    print("the maprect \(mapView.visibleMapRect.size)")
    //I find just this attributes for mapView

    }

我不知道如何从我的数据中获取视口。我无法在www。

中找到任何内容

目的地是我使用谷歌分析记录坐标，另一个工具评估数据。

有人有想法吗？非常感谢

Answer 1

<强> MapKit

let northEast = mapView.convertPoint(CGPoint(x: mapView.bounds.width, y: 0), toCoordinateFromView: mapView)
let southWest = mapView.convertPoint(CGPoint(x: 0, y: mapView.bounds.height), toCoordinateFromView: mapView)

mapView有一个属性＆＃34;投影＆＃34;在哪里可以使用＆＃34; coordinateForPoint＆＃34;将一个点从mapView转换为一个坐标。所以以下方法可行：

swift 3 for google maps

let northEast = mapView.projection.coordinate(for: CGPoint(x: mapView.layer.frame.width, y: 0))
let southWest = mapView.projection.coordinate(for: CGPoint(x: 0, y: mapView.layer.frame.height))

swift 2

let northEast = mapView.projection.coordinateForPoint(CGPoint(x: mapWidth, y: 0 ))
let southWest = mapView.projection.coordinateForPoint(CGPoint(x: 0, y: mapHeight))

您只需输入mapView的宽度和高度

即可

let northEast = mapView.convert(CGPoint(x: mapView.bounds.width, y: 0), toCoordinateFrom: mapView)
let southWest = mapView.convert(CGPoint(x: 0, y: mapView.bounds.height), toCoordinateFrom: mapView)

从mapView获取视口坐标？ regionDidChanged swift
