正在初始化GMSMapView崩溃

Question

​

我的程序在初始化GMSMapView对象时崩溃。例如：

class AppDelegate: UIResponder, UIApplicationDelegate, UISplitViewControllerDelegate {
var window: UIWindow?
let store = Store.default
let map: GMSMapView = GMSMapView()

func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplicationLaunchOptionsKey: Any]?) -> Bool {
    guard GMSServices.provideAPIKey(AppConstants.Keys.googleMaps.rawValue) else { fatalError("Can not initialize Google Map services") }

    print("Map: \(self.map)")

    return true
}

在初始化GMSMapView时，代码报告以下内容：

Thread 1: signal SIGABRT
libc++abi.dylib: terminating with uncaught exception of type NSException

Answer 1

class AppDelegate: UIResponder, UIApplicationDelegate, UISplitViewControllerDelegate {
var window: UIWindow?
let store = Store.default
var map: GMSMapView?
func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplicationLaunchOptionsKey: Any]?) -> Bool {
    guard GMSServices.provideAPIKey(AppConstants.Keys.googleMaps.rawValue) else { fatalError("Can not initialize Google Map services") }
    self.map = GMSMapView()
    print("Map: \(self.map)")

    return true
}

试着像这样改变它

检查控制台输出。您应该会看到以下错误：Terminating app due to uncaught exception 'GMSServicesException', reason: 'Google Maps SDK for iOS must be initialized via [GMSServices provideAPIKey:...] prior to use

您正在尝试在GMSService.provideAPIKey之前初始化mapView
