ios - 放大用户位置 - Swift

Question

我不知道如何让 map 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! 变种 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)
}

我已经查找了这个问题的答案，但没有在 Swift 中找到答案，也没有找到真正有效的答案。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一个区域。也许尝试这样做。
