获取推送通知令牌- iOS 10、Swift 3
获取推送通知令牌- iOS 10、Swift 3
提问于 2016-09-19 12:02:42
如何从新的xCode 8， iOS 10中的Swift 3获取设备令牌
以下是注册通知的代码：
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()
}
}在这里，我得到了令牌，但我得到了以下错误
Cannot invoke initializer for type 'UnsafePointer<CChar>' with an argument list of type '(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)
}有人能帮我解决这个问题吗？

此方法可能会解决iOS 10及更高版本中的问题：
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)

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

来自raywenderlich.com的Swift 3示例。
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)
