S'enregistrer pour les notifications Push dans Xcode 8/Swift 3.0?

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

    if #available(iOS 10, *) {

        //Notifications get posted to the function (delegate):  func userNotificationCenter(_ center: UNUserNotificationCenter, didReceive response: UNNotificationResponse, withCompletionHandler completionHandler: () -> Void)"


        UNUserNotificationCenter.current().requestAuthorization(options: [.alert, .badge, .sound]) { (granted, error) in

            guard error == nil else {
                //Display Error.. Handle Error.. etc..
                return
            }

            if granted {
                //Do stuff here..

                //Register for RemoteNotifications. Your Remote Notifications can display alerts now :)
                DispatchQueue.main.async {
                    application.registerForRemoteNotifications()
                }
            }
            else {
                //Handle user denying permissions..
            }
        }

        //Register for remote notifications.. If permission above is NOT granted, all notifications are delivered silently to AppDelegate.
        application.registerForRemoteNotifications()
    }
    else {
        let settings = UIUserNotificationSettings(types: [.alert, .badge, .sound], categories: nil)
        application.registerUserNotificationSettings(settings)
        application.registerForRemoteNotifications()
    }

    return true
}

j'ai eu des problèmes avec les réponses ici en convertissant l'objet de données deviceToken en une chaîne à envoyer à mon serveur avec la bêta actuelle de Xcode 8. Surtout celui qui utilisait deviceToken.description en 8.0b6 qui serait de retour "32 Octets", ce qui n'est pas très utile :)

C'est ce qui a fonctionné pour moi...

créer une extension sur les données pour mettre en œuvre une méthode "hexString":

extension Data {
    func hexString() -> String {
        return self.reduce("") { string, byte in
            string + String(format: "%02X", byte)
        }
    }
}

et puis utiliser que lorsque vous recevez le rappel à partir de l'enregistrement pour les notifications à distance:

func application(_ application: UIApplication, didRegisterForRemoteNotificationsWithDeviceToken deviceToken: Data) {
    let deviceTokenString = deviceToken.hexString()
    // Send to your server here...
}

dans iOS10 au lieu de votre code, vous devriez demander une autorisation pour la notification avec ce qui suit: (N'oubliez pas d'ajouter le UserNotifications Framework)

if #available(iOS 10.0, *) {
        UNUserNotificationCenter.current().requestAuthorization([.alert, .sound, .badge]) { (granted: Bool, error: NSError?) in
            // Do something here
        }
    }

aussi, le code correct pour vous est (utilisez dans le else de la condition précédente, par exemple):

let setting = UIUserNotificationSettings(types: [.alert, .badge, .sound], categories: nil)
UIApplication.shared().registerUserNotificationSettings(setting)
UIApplication.shared().registerForRemoteNotifications()

Enfin, assurez-vous que Push Notification est activé sous target -> Capabilities -> Push notification . (réglez-le sur On )

import UserNotifications  

ensuite, allez à l'éditeur de projet pour votre cible, et dans l'onglet Général, cherchez la section cadres et bibliothèques liés.

cliquez sur + et sélectionnez UserNotifications.cadre:

// iOS 12 support
if #available(iOS 12, *) {  
    UNUserNotificationCenter.current().requestAuthorization(options:[.badge, .alert, .sound, .provisional, .providesAppNotificationSettings, .criticalAlert]){ (granted, error) in }
    application.registerForRemoteNotifications()
}

// iOS 10 support
if #available(iOS 10, *) {  
    UNUserNotificationCenter.current().requestAuthorization(options:[.badge, .alert, .sound]){ (granted, error) in }
    application.registerForRemoteNotifications()
}
// iOS 9 support
else if #available(iOS 9, *) {  
    UIApplication.shared.registerUserNotificationSettings(UIUserNotificationSettings(types: [.badge, .sound, .alert], categories: nil))
    UIApplication.shared.registerForRemoteNotifications()
}
// iOS 8 support
else if #available(iOS 8, *) {  
    UIApplication.shared.registerUserNotificationSettings(UIUserNotificationSettings(types: [.badge, .sound, .alert], categories: nil))
    UIApplication.shared.registerForRemoteNotifications()
}
// iOS 7 support
else {  
    application.registerForRemoteNotifications(matching: [.badge, .sound, .alert])
}

Utiliser la Notification délégué méthodes

// Called when APNs has assigned the device a unique token
func application(_ application: UIApplication, didRegisterForRemoteNotificationsWithDeviceToken deviceToken: Data) {  
    // Convert token to string
    let deviceTokenString = deviceToken.reduce("", {"151920920" + String(format: "%02X", )})
    print("APNs device token: \(deviceTokenString)")
}

// Called when APNs failed to register the device for push notifications
func application(_ application: UIApplication, didFailToRegisterForRemoteNotificationsWithError error: Error) {  
    // Print the error to console (you should alert the user that registration failed)
    print("APNs registration failed: \(error)")
}

Pour la réception de notifications push

func application(_ application: UIApplication, didReceiveRemoteNotification userInfo: [AnyHashable : Any], fetchCompletionHandler completionHandler: @escaping (UIBackgroundFetchResult) -> Void) {
    completionHandler(UIBackgroundFetchResult.noData)
}

configurer les notifications push permet d'activer la fonctionnalité dans le Xcode 8 pour votre application. Tout simplement aller à l'éditeur de projet pour votre cible et puis cliquez sur L'onglet" capacités 1519140920". Rechercher Push Notifications et bascule sa valeur à sur .

eh Bien ce travail pour moi. Premier en AppDelegate

import UserNotifications

puis:

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

    func registerForRemoteNotification() {
        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()
                }
            }
        }
        else {
            UIApplication.shared.registerUserNotificationSettings(UIUserNotificationSettings(types: [.sound, .alert, .badge], categories: nil))
            UIApplication.shared.registerForRemoteNotifications()
        }
    }

Pour obtenir devicetoken:

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

       let deviceTokenString = deviceToken.reduce("", {"151920920" + String(format: "%02X", )})

}

Heads up, vous devriez utiliser le thread principal pour cette action.

let center = UNUserNotificationCenter.current()
center.requestAuthorization(options:[.badge, .alert, .sound]) { (granted, error) in
        if granted {
            DispatchQueue.main.async(execute: {
                UIApplication.shared.registerForRemoteNotifications()
            })
        }
    }

premier , écouter le statut de notification de l'utilisateur, i.e., registerForRemoteNotifications() pour obtenir un jeton de périphérique APNs;

deuxième , demande d'autorisation. En étant autorisé par l'utilisateur, deviceToken sera envoyé à l'auditeur, le AppDelegate ;

troisième , signalez le token de périphérique à votre serveur.

extension AppDelegate {
    /// 1. 监听 deviceToken
    UIApplication.shared.registerForRemoteNotifications()

    /// 2. 向操作系统索要推送权限（并获取推送 token）
    static func registerRemoteNotifications() {
        if #available(iOS 10, *) {
            let uc = UNUserNotificationCenter.current()
            uc.delegate = UIApplication.shared.delegate as? AppDelegate
            uc.requestAuthorization(options: [.alert, .badge, .sound]) { (granted, error) in
                if let error = error { // 无论是拒绝推送，还是不提供 aps-certificate，此 error 始终为 nil
                    print("UNUserNotificationCenter 注册通知失败, \(error)")
                }
                DispatchQueue.main.async {
                    onAuthorization(granted: granted)
                }
            }
        } else {
            let app = UIApplication.shared
            app.registerUserNotificationSettings(UIUserNotificationSettings(types: [.badge, .sound, .alert], categories: nil)) // 获取用户授权
        }
    }

    // 在 app.registerUserNotificationSettings() 之后收到用户接受或拒绝及默拒后，此委托方法被调用
    func application(_ app: UIApplication, didRegister notificationSettings: UIUserNotificationSettings) {
        // 已申请推送权限，所作的检测才有效
        // a 征询推送许可时，用户把app切到后台，就等价于默拒了推送
        // b 在系统设置里打开推送，但关掉所有形式的提醒，等价于拒绝推送，得不token，也收不推送
        // c 关掉badge, alert和sound 时，notificationSettings.types.rawValue 等于 0 和 app.isRegisteredForRemoteNotifications 成立，但能得到token，也能收到推送（锁屏和通知中心也能看到推送），这说明types涵盖并不全面
        // 对于模拟器来说，由于不能接收推送，所以 isRegisteredForRemoteNotifications 始终为 false
       onAuthorization(granted: app.isRegisteredForRemoteNotifications)
    }

    static func onAuthorization(granted: Bool) {
        guard granted else { return }
        // do something
    }
}

extension AppDelegate {
    func application(_ app: UIApplication, didRegisterForRemoteNotificationsWithDeviceToken deviceToken: Data) {
        //
    }

    // 模拟器得不到 token，没配置 aps-certificate 的项目也得不到 token，网络原因也可能导致得不到 token
    func application(_ app: UIApplication, didFailToRegisterForRemoteNotificationsWithError error: Error) {
        //
    }
}

la réponse de ast1 est très simple et utile. Il fonctionne pour moi, merci beaucoup. Je veux juste le faire ici, pour que les gens qui ont besoin de cette réponse puissent la trouver facilement. Donc, voici mon code d'enregistrement de notification locale et distante (push).

    //1. In Appdelegate: didFinishLaunchingWithOptions add these line of codes
    let mynotif = UNUserNotificationCenter.current()
    mynotif.requestAuthorization(options: [.alert, .sound, .badge]) {(granted, error) in }//register and ask user's permission for local notification

    //2. Add these functions at the bottom of your AppDelegate before the last "}"
    func application(_ application: UIApplication, didRegister notificationSettings: UNNotificationSettings) {
        application.registerForRemoteNotifications()//register for push notif after users granted their permission for showing notification
}
    func application(_ application: UIApplication, didRegisterForRemoteNotificationsWithDeviceToken deviceToken: Data) {
    let tokenString = deviceToken.reduce("", {"151900920" + String(format: "%02X", )})
    print("Device Token: \(tokenString)")//print device token in debugger console
}
    func application(_ application: UIApplication, didFailToRegisterForRemoteNotificationsWithError error: Error) {
    print("Failed to register: \(error)")//print error in debugger console
}

il suffit de faire ce qui suit dans didFinishWithLaunching: :

if #available(iOS 10.0, *) {

    let center = UNUserNotificationCenter.current()

    center.delegate = self
    center.requestAuthorization(options: []) { _, _ in
        application.registerForRemoteNotifications()
    }
}

Se souvenir de déclaration d'importation:

import UserNotifications

func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [NSObject: AnyObject]?) -> Bool {
    let notificationCenter = UNUserNotificationCenter.current()
    notificationCenter.requestAuthorization([.alert , .sound]) { (finished, err) in
        if err == nil {
            application.registerForRemoteNotifications()
        }
    }
    return true
}

regardez ce code commenté:
