Question

在iOS 10+中，当我启动我的应用程序时，我得到两次请求通知和位置服务。第一个短暂出现并立即消失而不允许我做任何动作，然后我得到第二个弹出窗口，其中有正常的行为等待＆＃34;允许＆＃34;或者＆＃34;拒绝＆＃34;来自用户。

以下是此问题的gif。

以下是我的AppDelegate中的通知方法：

 func applicationDidBecomeActive(_ application: UIApplication) {
    // Restart any tasks that were paused (or not yet started) while the application was inactive. If the application was previously in the background, optionally refresh the user interface.
    if #available(iOS 10, *) { // iOS 10 support
        UNUserNotificationCenter.current().requestAuthorization(options:[.badge, .alert, .sound]){ (granted, error) in }
        UIApplication.shared.registerForRemoteNotifications()
    }else if #available(iOS 9, *) { // iOS 9 support
        UIApplication.shared.registerUserNotificationSettings(UIUserNotificationSettings(types: [.badge, .sound, .alert], categories: nil))
        UIApplication.shared.registerForRemoteNotifications()
    }
    AppEventsLogger.activate(application)

}

以下是我的AppDelegate中的位置服务方法：

 func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplicationLaunchOptionsKey: Any]?) -> Bool {

    //
    self.setupLocationService()


 func setupLocationService(){
    self.locationManager.delegate = self
    let status = CLLocationManager.authorizationStatus()
    if status == .authorizedWhenInUse || status == .authorizedAlways{
        self.locationManager.desiredAccuracy = kCLLocationAccuracyHundredMeters
        self.locationManager.startUpdatingLocation()
    }else if status == .notDetermined{
        self.locationManager.requestWhenInUseAuthorization()
        self.locationManager.requestAlwaysAuthorization()
    }else{
        print("Location service disabled")
    }
}

Answer 1

由于您要求两个权限请求，因此发生此问题。因此，您需要将代码更改为以下内容。

UNUserNotificationCenter.current().requestAuthorization(options: [.alert, .badge, .sound], completionHandler: { (authorised, error) in
    self.setupLocationService()
})

只需像这样更新您的代码。这将首先询问您通知授权请求。根据用户与弹出窗口的交互，然后询问您的位置许可请求。

我希望这对你有用。

Write notification code in didFinishLaunchingWithOptions

@UIApplicationMain
class AppDelegate: UIResponder, UIApplicationDelegate,CLLocationManagerDelegate {

func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplicationLaunchOptionsKey: Any]?) -> Bool {
    // Override point for customization after application launch.

    setupLocationService()

    if #available(iOS 10.0, *) {
        // For iOS 10 display notification (sent via APNS)
        UNUserNotificationCenter.current().delegate = self

        let authOptions: UNAuthorizationOptions = [.alert, .badge, .sound]
        UNUserNotificationCenter.current().requestAuthorization(
            options: authOptions,
            completionHandler: {_, _ in })
    } else {
        let settings: UIUserNotificationSettings =
            UIUserNotificationSettings(types: [.alert, .badge, .sound], categories: nil)
        application.registerUserNotificationSettings(settings)
    }
    application.registerForRemoteNotifications()

    return true
}

func setupLocationService(){
    self.locationManager.delegate = self
    let status = CLLocationManager.authorizationStatus()
    if status == .authorizedWhenInUse || status == .authorizedAlways{
        self.locationManager.desiredAccuracy = kCLLocationAccuracyHundredMeters
        self.locationManager.startUpdatingLocation()
    }else if status == .notDetermined{
        self.locationManager.requestWhenInUseAuthorization()
        self.locationManager.requestAlwaysAuthorization()
    }else{
        print("Location service disabled")


    }
    }

}

iOS通知和位置服务权限在启动时多次显示
