正确显示UIView中的谷歌地图

Question

我在iOS上使用谷歌地图。

这是我的代码：

import UIKit
import GoogleMaps

ViewController: UIViewController {

@IBOutlet weak var myMapView: GMSMapView!

override func viewDidLoad() {
    super.viewDidLoad()
}


override func viewDidAppear(_ animated: Bool) {
    // Create a GMSCameraPosition that tells the map to display the
    // coordinate -33.86,151.20 at zoom level 6.
    let camera = GMSCameraPosition.camera(withLatitude: +31.75097946, longitude: +35.23694368, zoom: 17.0)
    let mapView = GMSMapView.map(withFrame: CGRect.zero, camera: camera)
    //mapView.isMyLocationEnabled = true
    mapView.mapType =  .terrain



    self.view = mapView
    //self.myMapView = mapView



    // Creates a marker in the center of the map.
    let marker = GMSMarker()
    marker.position = CLLocationCoordinate2D(latitude: +31.75097946, longitude: +35.23694368)
    marker.title = "Eden VidanPeled"

    //marker.snippet = "Australia"
    marker.map = mapView
    marker.opacity = 1.0
   }

在Interface Builder中，我有一个带有GMSMapView类的UIView。当我将我的地图附加到UIViewController时，我得到了我的lat-long coords。当我尝试将地图映射到UIView时，我得到了不同的地图，缩放级别等， 如下图所示。

如何正确描绘UIView地图？ 附：我尝试了viewDidLoad和viewDidAppear，结果相同。 感谢

您已经为IBOutlet

创建了GMSMapView

它将为您创建一个地图实例。因此，无需再创建一个GMSMapView实例并将其分配给类变量。

override func viewDidAppear(_ animated: Bool) {
     // Create a GMSCameraPosition that tells the map to display the
     // coordinate -33.86,151.20 at zoom level 6.

     let camera = GMSCameraPosition.camera(withLatitude: +31.75097946, longitude: +35.23694368, zoom: 17.0)

     self.myMapView.mapType =  .terrain

     self.myMapView.camera = camera


    // Creates a marker in the center of the map.
    let marker = GMSMarker()
    marker.position = CLLocationCoordinate2D(latitude: +31.75097946, longitude: +35.23694368)
    marker.title = "Eden VidanPeled"

    //marker.snippet = "Australia"
    marker.map = self.myMapView
    marker.opacity = 1.0
}
