问题描述

我在项目中使用GoogleMaps Pod.我的故事板之一出现错误:

I'm using GoogleMaps Pod in my project. I have error in one of my Storyboard:

我已将视图类设置为GMSMapView:

I have set view class to GMSMapView:

应用程序正在模拟器上运行.我该如何解决此错误?这会导致整个情节提要空白.

App is working on simulator. How I can fix this error? It causes whole storyboard to be blank.

推荐答案

通过在模拟器中编写代码来手动使用GMSMapView；而不是在情节提要中使用GMSMapView.

Use GMSMapView manually by writing code in simulator; Instead of using GMSMapView in storyboard.

如果要在多个屏幕中使用地图.然后手动为所有文件编写代码.

If you are using maps in multiple screen. then write code manually for all file.

@IBOutlet weak var map_Views: UIView!
var map_View = GMSMapView()
override func viewDidLoad() {

    super.viewDidLoad()

    let camera = GMSCameraPosition.camera(withLatitude: Double(main_latitude)!, longitude: Double(main_longitude)!, zoom: 6.0)
     map_View = GMSMapView.map(withFrame: CGRect.zero, camera: camera)
    map_Views = map_View

    map_View.camera = GMSCameraPosition.camera(withLatitude:Double(main_latitude)!,
                                                    longitude:Double(main_longitude)!,
                                                    zoom:10.0,
                                                    bearing: 0,
                                                    viewingAngle: 0)

}
