Obtenga el token de notificación push-iOS 10, Swift 3

Question

¿Cómo obtener el token del dispositivo del nuevo xCode 8, Swift 3 en iOS 10?

Aquí el código para registrar la notificación:

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

        DispatchQueue.main.async {
            let settings = UIUserNotificationSettings(types: [.badge, .sound, .alert], categories: nil)
            UIApplication.shared.registerUserNotificationSettings(settings)
        }
        return true
    }

func application(_ application: UIApplication, didRegister notificationSettings: UIUserNotificationSettings) {
        if notificationSettings.types != UIUserNotificationType() {
            application.registerForRemoteNotifications()
        }
    }

Aquí para obtener el token, pero aparece el error "No se puede invocar el inicializador para el tipo ''UnsafePointer'' con una lista de argumentos de tipo ''(UnsafeRawPointer)''":

func application(_ application: UIApplication, didRegisterForRemoteNotificationsWithDeviceToken deviceToken: Data) {
        let chars = UnsafePointer<CChar>((deviceToken as NSData).bytes)
        var token = ""

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

        print("Registration succeeded!")
        print("Token: ", token)
    }

¿Alguien puede ayudar a resolverlo?

Gracias

Answer 1

Ante el mismo problema, esto es lo único que me ayudó:

func application(_ application: UIApplication, didRegisterForRemoteNotificationsWithDeviceToken deviceToken: Data) {
    let token = String(format: "%@", deviceToken as CVarArg)
        .trimmingCharacters(in: CharacterSet(charactersIn: "<>"))
        .replacingOccurrences(of: " ", with: "")
}

Answer 2

El siguiente snnipet está trabajando con la solución de Eric Aya:

let token = deviceToken.reduce("", {$0 + String(format: "%02X", $1)})

Gracias por toda la ayuda :)

Answer 3

Este método puede resolver su problema en iOS 10 y superior:

func application(_ application: UIApplication, didRegisterForRemoteNotificationsWithDeviceToken deviceToken: Data) {
    var token = ""
    for i in 0..<deviceToken.count {
        token = token + String(format: "%02.2hhx", arguments: [deviceToken[i]])
    }
    print(token)
}

Answer 4

Podría funcionar:

let chars = UnsafePointer<CChar>((deviceToken as NSData).bytes.assumingMemoryBound(to:CChar.self))

¡Gracias!

Swift 3 ejemplo tomado de raywenderlich.com .

func application(_ application: UIApplication, didRegisterForRemoteNotificationsWithDeviceToken deviceToken: Data){
    let tokenParts = deviceToken.map { data -> String in
        return String(format: "%02.2hhx", data)
    }  
    let token = tokenParts.joined()
    print(token)
}

Una línea:

func application(_ application: UIApplication, didRegisterForRemoteNotificationsWithDeviceToken deviceToken: Data) {
    let apnsDeviceToken = deviceToken.map {String(format: "%02.2hhx", $0)}.joined()
}

De este tutorial.

Código de trabajo para obtener el token de notificación push - iOS 11 o superior, Swift 4

Solicitar permiso del usuario

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

    let notificationTypes: UIUserNotificationType = [UIUserNotificationType.alert,UIUserNotificationType.badge, UIUserNotificationType.sound]
    let pushNotificationSettings = UIUserNotificationSettings(types: notificationTypes, categories: nil)

    application.registerUserNotificationSettings(pushNotificationSettings)
    application.registerForRemoteNotifications()

    return true        
}

Obtención de token de dispositivo

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

    let token = deviceToken.map { String(format: "%02.2hhx", $0) }.joined()
    print(token) 
}

En caso de error

func application(_ application: UIApplication, didFailToRegisterForRemoteNotificationsWithError error: Error) {

    print("i am not available in simulator /(error)")
}

var pushToken = String(format: "%@", deviceToken as CVarArg)
pushToken = pushToken.trimmingCharacters(in: CharacterSet(charactersIn: "<>"))
pushToken = pushToken.replacingOccurrences(of: " ", with: "")
