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()
}

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: "")
