【问题描述】：

我在我的应用程序SS here中添加了定位背景模式

但是，应用程序仍然无法使用启动选项键启动

UIApplication.LaunchOptionsKey.location

这是我的应用委托代码，

func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey: Any]?) -> Bool 
    // Override point for customization after application launch.
    addItem(name: "LaunchOptions: \(String(describing: launchOptions))")
    if let launchOptions = launchOptions 
        if launchOptions[UIApplication.LaunchOptionsKey.location] != nil 
            startLocationMonitoring()
        
    
    print("LaunchOptions: \(String(describing: launchOptions))")
    return true


func startLocationMonitoring() 
    locationManager?.delegate = nil
    locationManager = nil
    locationManager = CLLocationManager()
    locationManager?.delegate = self
    locationManager?.desiredAccuracy = kCLLocationAccuracyBestForNavigation
    locationManager?.distanceFilter = 1.0 // meters
    locationManager?.allowsBackgroundLocationUpdates = true
    locationManager?.activityType = .otherNavigation
    locationManager?.pausesLocationUpdatesAutomatically = false
    authStatusCheck()
    locationManager?.startUpdatingLocation()


func locationManager(_ manager: CLLocationManager, didUpdateLocations locations: [CLLocation]) 
    print(locations)
    if let appDelegate = (UIApplication.shared.delegate as? AppDelegate) 
        for location in locations 
            appDelegate.addItem(newLocation: location)
        
    

addItem 函数将位置变化或日志添加到核心数据中

【参考方案1】：

现在您可以在场景委托上获得启动选项。这是一个简单的例子：

func scene(_ scene: UIScene, willConnectTo session: UISceneSession, options connectionOptions: UIScene.ConnectionOptions)                 
          if let response = connectionOptions.notificationResponse 
             //get your launch info from here
             let location = response.notification.request.content.userInfo[UIApplication.LaunchOptionsKey.location]
    ...
