【中文标题】推送通知未在 iOS 10 设备中显示

【英文标题】：Push notification doesn't showing in iOS 10 devices

【问题描述】：

我是 Swift 新手，ios 10 中没有弹出推送通知，我做了所有配置。通知在 iOS 8 和 9 设备中显示（相同代码），但在 iOS 10 设备中不显示。代码就像（只添加了通知部分代码）。

private let brandFullery   : String = "some token key"

    var pushNotify : NSDictionary!

func application(application: UIApplication, didFinishLaunchingWithOptions launchOptions: [NSObject: AnyObject]?) -> Bool 

        UIApplication.sharedApplication().applicationIconBadgeNumber = 0
        UIApplication.sharedApplication().cancelAllLocalNotifications()

        MyCacheManager.sharedInstance.deviceId = UIDevice.currentDevice().identifierForVendor!.UUIDString



        application.registerUserNotificationSettings(UIUserNotificationSettings(forTypes: [.Sound, .Alert, .Badge], categories: nil))
        application.registerForRemoteNotifications()

        MyCacheManager.sharedInstance.deleteAllFileInDocument("LiveUserProfile")

        if let payload = launchOptions?[UIApplicationLaunchOptionsRemoteNotificationKey] as? NSDictionary, metData = payload["data"] as? NSDictionary 

            pushNotify = metData

            let aps = pushNotify["eventType"] as! NSString
            if aps != "INVITE_POINTS" && aps != "UPDATE_BEACON" && aps != "CREATE_REWARD" 

                MyCacheManager.sharedInstance.isFromNotification = aps as String
             else 
                if aps == "UPDATE_BEACON" 

                    MyCacheManager.sharedInstance.isBeaconUpdate = true 
                

                MyCacheManager.sharedInstance.isFromNotification = ""
            

            self.createMenuView()

         else 

            MyCacheManager.sharedInstance.isFromNotification = ""
            self.createMenuView()
        


        #if BRANDAPP

            Twitter.sharedInstance().startWithConsumerKey(brandTwitterAuthKey, consumerSecret: brandSecuriteKey)

            Flurry.startSession(brandFullery)
        #else
            Twitter.sharedInstance().startWithConsumerKey(userTwitterAuthKey, consumerSecret: userSecuriteKey)

            Flurry.startSession(userFullery)

        #endif

        Fabric.with([Twitter.self])

        UIApplication.sharedApplication().statusBarStyle = .LightContent

        return FBSDKApplicationDelegate.sharedInstance().application(application, didFinishLaunchingWithOptions: launchOptions)
    

//MARK: Push notification
    func application(application: UIApplication, didRegisterForRemoteNotificationsWithDeviceToken deviceToken: NSData) 

        var deviceTokenString : NSString = deviceToken.description;
        deviceTokenString = deviceTokenString.stringByTrimmingCharactersInSet(NSCharacterSet(charactersInString: "<>"))
        deviceTokenString = deviceTokenString.stringByReplacingOccurrencesOfString(" ", withString: "")

        MyCacheManager.sharedInstance.deviceToken = deviceTokenString as String
        MyCacheManager.sharedInstance.putDeviceToken(deviceTokenString)

         NSLog("device %@", deviceTokenString)
    


    func application(application: UIApplication, didFailToRegisterForRemoteNotificationsWithError error: NSError) 
    

    func application(application: UIApplication, didReceiveRemoteNotification userInfo: [NSObject : AnyObject]) 


        MyCacheManager.sharedInstance.isFromNotification = "MSG"
        print(userInfo)
    

请任何人帮助我完成这项工作。非常感谢。

【问题讨论】：

您必须为 iOS 10 使用更新的 API，即 UNUserNotificationCenter 。请参考***.com/questions/37807302/…

Registering for Push Notifications in Xcode 8/Swift 3.0?的可能重复

【参考方案1】：

你必须注册 ios 10。试试这个

   import UserNotifications

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

 // iOS 10+ support
            if #available(iOS 10.0, *) 
                let center  = UNUserNotificationCenter.current()
                center.delegate = self
                center.requestAuthorization(options: [.sound, .alert, .badge])  (granted, error) in
                    if error == nil
                        UIApplication.shared.registerForRemoteNotifications()
                    
                

            
                // iOS 9 support or less
            else 
                UIApplication.shared.registerUserNotificationSettings(UIUserNotificationSettings(types: [.sound, .alert, .badge], categories: nil))
                UIApplication.shared.registerForRemoteNotifications()
            


// Called when APNs failed to register the device for push notifications

func application(_ application: UIApplication, didRegisterForRemoteNotificationsWithDeviceToken deviceToken: Data) 

   let deviceTokenString = deviceToken.reduce("", $0 + String(format: "%02X", $1))
   print("APNs device token: \(deviceTokenString)")

然后你会收到通知

   // Receive displayed notifications for iOS 10 devices.
    //Called when a notification is delivered to a foreground app.
    @available(iOS 10.0, *)
    func userNotificationCenter(_ center: UNUserNotificationCenter, willPresent notification: UNNotification, withCompletionHandler completionHandler: @escaping (UNNotificationPresentationOptions) -> Void) 
        let userInfo = notification.request.content.userInfo
        print("User Info = ",userInfo)

        completionHandler([.alert, .badge, .sound])
    

    //MARK:- Handle push notifications
    //Called to let your app know which action was selected by the user for a given notification.
    @available(iOS 10.0, *)
    func userNotificationCenter(_ center: UNUserNotificationCenter, didReceive response: UNNotificationResponse, withCompletionHandler completionHandler: @escaping () -> Void) 

        let userInfo = response.notification.request.content.userInfo

        print("User Info = ",userInfo)
        //handle the notification form here when cliked.
        completionHandler()
    

【讨论】：

显示未知属性'转义'错误。而在 didRegisterForRemoteNotificationsWithDeviceToken 类型的“数据”方法值中没有成员“减少”

使用 Xcode 8.0 我还添加了 UserNotifications.framework

注册推送通知后是否还出现Showing Unknown attribute'escaping'错误？

您在哪个部分遇到了错误？你能发布更新的代码吗？

//通知传递到前台应用时调用。 @available(iOS 10.0, *) func userNotificationCenter(_center: UNUserNotificationCenter, willPresent notification: UNNotification, withCompletionHandler completionHandler: @escaping (UNNotificationPresentationOptions) -> Void) let userInfo = notification.request.content.userInfo print("User Info = " ,userInfo) completionHandler([.alert, .badge, .sound]) 继续......

【参考方案2】：

简单的形式是

if #available(iOS 10, *) 
        UNUserNotificationCenter.current().requestAuthorization(options:[.badge, .alert, .sound]) (granted, error) in 
        application.registerForRemoteNotifications()
    
    else 
        UIApplication.shared.registerUserNotificationSettings(UIUserNotificationSettings(types: [.badge, .sound, .alert], categories: nil))
        UIApplication.shared.registerForRemoteNotifications()
    

然后 IOS 10 提供了新的代理

func application(_ application: UIApplication, didRegister notificationSettings: UIUserNotificationSettings) 



func application(_ application: UIApplication, didRegisterForRemoteNotificationsWithDeviceToken deviceToken: Data) 
    //here we will get the device token
