在Swift中注册远程通知时未收到设备令牌

Question

注册远程通知时,我以某种方式无法接收设备令牌.我得到模式说"你想让App X能够发送给你通知",但是当我接受它时,不会调用didRegisterForRemoteNotifications函数.

当我使用以下代码在iOS 8/Swift中注册远程通知时:

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

这些功能根本没有被触发:

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

和

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

但是当我记录这个

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

我收到

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

我的配置文件和证书都按顺序排列.

有其他人有这个问题吗？

你可以试试这个

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:Swift 2.x的更新

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
    }

func application(application: UIApplication, didRegisterForRemoteNotificationsWithDeviceToken deviceToken: NSData) {
let characterSet = CharacterSet(charactersIn: "<>")
    let deviceTokenString = deviceToken.description.trimmingCharacters(in: characterSet).replacingOccurrences(of: " ", with: "");
    print(deviceTokenString)
