ios - CLLocation Manager 检查 requestAlwaysAuthorization，如果不接受则退出应用程序

Question

我有 requestAlwaysAuthorization，如果用户不接受 requestAlwaysAuthorization 我想在应用程序中退出？

How can I do it ?

我的代码在下面。

import CoreLocation

 public var locationManager = CLLocationManager()

    override func viewDidLoad() {
        super.viewDidLoad()


        locationManager.delegate = self
        locationManager.requestAlwaysAuthorization()
        locationManager.startUpdatingLocation()

}



    func locationManager(_ manager: CLLocationManager, didUpdateLocations locations: [CLLocation]) {

        let altitudeG = locations.last?.altitude
        let longitudeG = locations.last?.coordinate.longitude
        let latitudeG = locations.last?.coordinate.latitude

print("\(altitudeG) \(longitudeG) \(latitudeG)")

    }

在错误情况下调用此委托(delegate)方法:

func locationManager(manager: CLLocationManager, didFailWithError error: NSError) {
    print(error)
    // handle not authorized error here. You might want to quit on specific errors (unauthorized) only. Check the error.

    UIControl().sendAction(#selector(URLSessionTask.suspend), to: UIApplication.shared, for: nil) 
}

您还可以在让 CLLocationManager 失败之前检查当前权限状态:

if CLLocationManager.locationServicesEnabled() {
    switch(CLLocationManager.authorizationStatus()) {
        case .notDetermined, .restricted, .denied:
            print("No access")
        case .authorizedAlways, .authorizedWhenInUse:
            print("Access")
        }
    } else {
        print("Location services are not enabled")
}

基于意见:我考虑退出该应用程序，而不是向用户提供可理解的非常糟糕的用户体验反馈。
