获取推送通知令牌 - iOS 10、Swift 3 [英] Get the push notification token - iOS 10, Swift 3

问题描述

如何从 iOS 10 中的新 xCode 8、Swift 3 获取设备令牌?

How to get the device token from new xCode 8, Swift 3 in iOS 10?

这是注册通知的代码:

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，但出现以下错误

Here i get the token, but i get the following error

Cannot invoke initializer for type 'UnsafePointer<CChar>' with an argument list of type '(UnsafeRawPointer)':

<小时>

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)
}

谁能帮我解决一下?

推荐答案

此方法可能会解决您在 iOS 10 及更高版本中的问题:

This method may solve your problem in iOS 10 and greater:

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)
}
