在斯威夫特远程通知注册时未收到设备令牌 [英] Device Token not received when registering for remote notifications in Swift

问题描述

我莫名其妙地为远程通知注册时无法接收设备令牌。我得到的语气说：你要允许X程序，以便能够向您发送notificaitons，但是当我接受它，则didRegisterForRemoteNotifications函数没有被调用。

I somehow can not receive the device token when registering for remote notifications. I get the modal saying "Do you want to allow App X to be able to send you notificaitons", but when I accept it, the didRegisterForRemoteNotifications function is not called.

当我注册使用这个code iOS中8 /斯威夫特远程通知：

When I register for remote notifications in iOS 8/Swift using this code:

    UIApplication.sharedApplication().registerForRemoteNotifications()
    let settings = UIUserNotificationSettings(forTypes: UIUserNotificationType.Badge | UIUserNotificationType.Alert | UIUserNotificationType.Sound, categories: nil)
    UIApplication.sharedApplication().registerUserNotificationSettings(settings)
    UIApplication.sharedApplication().registerForRemoteNotifications()

这些功能不会被触发在所有的：

These functions are not triggered at all:

   func application(application: UIApplication, didRegisterForRemoteNotificationsWithDeviceToken deviceToken: NSData!) 

和

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

但是当我登录这个

however when I log this

println("current settings \(UIApplication.sharedApplication().currentUserNotificationSettings()) and \(UIApplication.sharedApplication().isRegisteredForRemoteNotifications())")

我接受

"current settings <UIUserNotificationSettings: 0x170437120; types: (UIUserNotificationTypeAlert UIUserNotificationTypeBadge UIUserNotificationTypeSound);> and true" 

我的provisioning profile和证书AR一切为了。

My provisioning profile and certificates ar all in order.

已经有人人都有这个问题？

Has someone else had this problem?

推荐答案

您可以试试这个

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

        var types: UIUserNotificationType = UIUserNotificationType.Badge |
            UIUserNotificationType.Alert |
            UIUserNotificationType.Sound

        var settings: UIUserNotificationSettings = UIUserNotificationSettings(forTypes: types, categories: nil)

        application.registerUserNotificationSettings(settings)
        application.registerForRemoteNotifications()

        return true
    }

    func application(application: UIApplication, didRegisterForRemoteNotificationsWithDeviceToken deviceToken: NSData) {

        var characterSet: NSCharacterSet = NSCharacterSet(charactersInString: "<>")

        var deviceTokenString: String = (deviceToken.description as NSString)
            .stringByTrimmingCharactersInSet(characterSet)
            .stringByReplacingOccurrencesOfString( " ", withString: "") as String

        println(deviceTokenString)

    }

编辑：更新斯威夫特2.X

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


        let settings = UIUserNotificationSettings(forTypes: [.Alert, .Badge, .Sound], categories: nil)

        application.registerUserNotificationSettings(settings)
        application.registerForRemoteNotifications()

        return true
    }
