xcode - 我应该在 AppDelegate 还是 ViewController 中初始 LocationManager 设置 [Swift]

Question

我是 IOS 开发新手。我正在学习 coreLocation，我需要在 ViewComtroller.swift 代码中初始化位置服务，例如

func initLocationManager() {
    locationManager = CLLocationManager()
    locationManager.delegate = self
    locationManager.desiredAccuracy = 5
    locationManager.startUpdatingLocation()
    locationManager.requestAlwaysAuthorization()
    if CLLocationManager.locationServicesEnabled() {
        print("location Services Enabled")
    }
}

I have a question that some command such as locationManager.requestAlwaysAuthorization() needs to run only once when the app start right? But If I add it in the ViewDidLoad(), it will run every time I back to the view scene.

我需要将它们放入 AppDelegate.swift 中吗？我已经尝试这样做了。但我不知道如何将 AppDelegate.swift 与其他 .swift

连接

有谁知道一些让应用程序运行得更好、更高效的解决方案

当您在设置这行代码 locationManager.delegate = nil 后获取位置时，不会调用其委托(delegate)方法。
