ios - 调整谷歌地图 Swift 4 的大小

Question

我已按照 Google map 入门教程进行操作，但 map 位于状态栏下方，我不希望这样。因此，我使用 GMSMapView 的类属性创建了另一个 View ，并将创建的 map 链接到它。但是，当我运行代码时，我得到:

terminating with uncaught exception of type NSException

然后它转到 AppDelegate.swift 文件说:

Thread 1: signal SIGABRT

我不知道自己做错了什么，也找不到解决问题的答案。

这是我的 swift 4 代码:

import UIKit
import GoogleMaps

class FirstViewController: UIViewController {
    @IBOutlet weak var mapView: GMSMapView!

    override func viewDidLoad() {
        super.viewDidLoad()
        GMSServices.provideAPIKey("AIzaSyDNpN4_CfRBAY60U7qgWQIqJAwvjEFMwNk")
        let camera = GMSCameraPosition.camera(withLatitude: 41.3114, longitude: -105.5911, zoom: 15)
        mapView = GMSMapView.map(withFrame: CGRect.zero, camera: camera)

        view.addSubview(mapView)
    }
}

当 Storyboard中有 mapview 时，您不需要再次初始化它并添加为 subview 。

你应该在 AppDelegate 中移动设置 API key

class AppDelegate: UIResponder, UIApplicationDelegate {

    var window: UIWindow?


    func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplicationLaunchOptionsKey: Any]?) -> Bool {
        GMSServices.provideAPIKey("AIzaSyDNpN4_CfRBAY60U7qgWQIqJAwvjEFMwNk")
        return true
    }
}

View Controller

class ViewController: UIViewController{

    @IBOutlet weak var mapView: GMSMapView!

    override func viewDidLoad() {
        super.viewDidLoad()
        mapView.camera = GMSCameraPosition.camera(withLatitude: 41.3114, longitude: -105.5911, zoom: 15)
    }
}
