註冊推送通知功能不會被調用

我正在做這個需要推送通知的甜美應用程序。註冊推送通知功能不會被調用

但是，當試圖抓取Push令牌時，並不是所有必需的函數都被執行。

用戶不會得到跟此警報：

當用戶點擊OK我通過我的代碼退一步，看到不是一切被執行：

override func viewDidLoad(){ 
    let tapper = UITapGestureRecognizer(target: view, action:#selector(UIView.endEditing)) 
    tapper.cancelsTouchesInView = false 
    view.addGestureRecognizer(tapper) 

    print("gets called") 
    registerForPushNotifications(UIApplication.sharedApplication()) 
} 

func registerForPushNotifications(application: UIApplication) { 
    print("gets called") 
    let notificationSettings = UIUserNotificationSettings(
     forTypes: [.Badge, .Sound, .Alert], categories: nil) 
    application.registerUserNotificationSettings(notificationSettings) 
} 

func application(application: UIApplication, didRegisterUserNotificationSettings notificationSettings: UIUserNotificationSettings) { 
    print("doesn't get called") 
    if notificationSettings.types != .None { 
     application.registerForRemoteNotifications() 
    } 
} 

func application(application: UIApplication, didRegisterForRemoteNotificationsWithDeviceToken deviceToken: NSData) { 
    print("doesn't get called") 
    let tokenChars = UnsafePointer<CChar>(deviceToken.bytes) 
    var apnsTokenString = "" 

    for i in 0..<deviceToken.length { 
     apnsTokenString += String(format: "%02.2hhx", arguments: [tokenChars[i]]) 
    } 

    Constant.pushToken = apnsTokenString 

    print("Device Token:", Constant.pushToken) 
} 

func application(application: UIApplication, didFailToRegisterForRemoteNotificationsWithError error: NSError) { 
    debugPrint("Error Registering Remote Notification") 
}

在我的控制檯打印如下：

含義，並不是所有需要的功能調用。我究竟做錯了什麼？

沒有調用didRegisterForRemoteNotificationsWithDeviceToken func的權利？請參閱此鏈接 - http://stackoverflow.com/questions/39490605/push-notification-issue-with-ios-10/39506524#39506524 –

不，那個不會被叫。這正是我需要調用的功能。 –

好吧，按照這個鏈接中給出的步驟 - http://stackoverflow.com/questions/39490605/push-notification-issue-with-ios-10/39506524#39506524 –

假設你在你的問題發佈的代碼是在您的視圖控制器類，問題是，你需要把UIApplicationDelegate方法在實際的應用程序委託類，不是視圖控制器類。只需將這些方法移到適當的班級，他們就能工作。

你的意思是將底部的3個函數移動到AppDelegate.swift類吧？ –

是的，就是這樣。 – rmaddy

只要使用這個代碼

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


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

      application.registerUserNotificationSettings(settings) 
      application.registerForRemoteNotifications() 
} 



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

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

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

不適合我。第二個函數沒有被調用。 –

你只需要在App Delegate中調用 –
