放大用户位置 - Swift

Question

我不知道如何让地图从 viewDidLoad 放大用户位置。我尝试设置一个区域，但没有用。这是我的代码，有什么提示吗？

@IBOutlet 弱变量 mapView：MKMapView！变量MapViewLocationManager:CLLocationManager！ = CLLocationManager() var currentLocation：PFGeoPoint！ = PFGeoPoint()

override func viewDidLoad() {
    super.viewDidLoad()
    self.mapView.showsUserLocation = true
    mapView.delegate = self
   MapViewLocationManager.delegate = self
    mapView.setUserTrackingMode(MKUserTrackingMode.Follow, animated: true)
}

我已经查找了此问题的答案，但未在 Swift 中找到答案或实际有效的答案。谢谢！！

Answer 1

我会尝试这样的事情：

    let latitude:CLLocationDegrees = //insert latitutde

    let longitude:CLLocationDegrees = //insert longitude

    let latDelta:CLLocationDegrees = 0.05

    let lonDelta:CLLocationDegrees = 0.05

    let span = MKCoordinateSpanMake(latDelta, lonDelta)

    let location = CLLocationCoordinate2DMake(latitude, longitude)

    let region = MKCoordinateRegionMake(location, span)

    mapView.setRegion(region, animated: false)

我看到你说你试过设置区域。也许尝试这样做。

Answer 2

在大多数应用程序中，实现了一个 'current location' 按钮。一个简单的方法是这样的：

@IBAction func myLocationButtonTapped(_ sender: Any) {

    mapView.showsUserLocation = true
    mapView.setUserTrackingMode(.follow, animated: true)

}

一旦用户平移或缩放地图，跟踪将停止。所以对我来说已经足够了。

Answer 3

你一定要试试这个。它将缩放地图。

let span = MKCoordinateSpanMake(0.050, 0.050)
let region = MKCoordinateRegion(center: CLLocationCoordinate2D(latitude: 23.0225, longitude: 72.5714), span: span)
mapView.setRegion(region, animated: true)`

Answer 4

@IBOutlet weak var conscienceMap: MKMapView!

override func viewDidLoad() {
    super.viewDidLoad()
    conscienceMap.showsUserLocation = true
    conscienceMap.setUserTrackingMode(MKUserTrackingMode.follow, animated: true)
}
