Getting Remote Notification Device Token in Swift 4?
提问by Sandip Gill
I am using this code to get the Notification Center Device token.
我正在使用此代码获取通知中心设备令牌。
It was working in Swift 3 but not working in Swift 4. What changed?
它在 Swift 3 中有效，但在 Swift 4 中无效。发生了什么变化？
if #available(iOS 10.0, *) {
let center = UNUserNotificationCenter.current()
center.requestAuthorization(options:[.badge, .alert, .sound]) { (granted, error) in
}
}
func application(_ application: UIApplication, didRegisterForRemoteNotificationsWithDeviceToken deviceToken: Data) {
let deviceTokenString = deviceToken.reduce("", {import Foundation
extension Data {
var hexString: String {
let hexString = map { String(format: "%02.2hhx", func application(_ application: UIApplication, didRegisterForRemoteNotificationsWithDeviceToken deviceToken: Data) {
let deviceTokenString = deviceToken.hexString
print(deviceTokenString)
}
) }.joined()
return hexString
}
}
+ String(format: "%02X", )})
print(deviceTokenString)
}

Assuming that you already checked that everything has been setup right, based on your code, it seems that it should works fine, all you have to do is to change the format to %02.2hhxinstead of %02Xto get the appropriate hex string. Thus you should get a valid one.
假设您已经检查过所有设置是否正确，根据您的代码，它似乎应该可以正常工作，您所要做的就是将格式更改为%02.2hhx而不是%02X获取适当的十六进制字符串。因此你应该得到一个有效的。
As a good practice, you could add data extensioninto your project for getting the string:
作为一种好的做法，您可以将数据扩展添加到您的项目中以获取字符串：
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
}
Usage:
用法：
func application(_ application: UIApplication, didRegisterForRemoteNotificationsWithDeviceToken deviceToken: Data) {
let token = deviceToken.map { String(format: "%02.2hhx", func application(_ application: UIApplication, didFailToRegisterForRemoteNotificationsWithError error: Error) {
print("i am not available in simulator :( \(error)")
}
) }.joined()
print(token)
}

Request user permission
请求用户权限
func application(_ application: UIApplication, didRegisterForRemoteNotificationsWithDeviceToken deviceToken: Data)
{
let tokenChars = (deviceToken as NSData).bytes.bindMemory(to: CChar.self, capacity: deviceToken.count)
var tokenString = ""
for i in 0..<deviceToken.count {
tokenString += String(format: "%02.2hhx", arguments: [tokenChars[i]])
}
print("tokenString: \(tokenString)")
}

func application(_ application: UIApplication, didRegisterForRemoteNotificationsWithDeviceToken deviceToken: Data) {
// Convert token to string
let deviceTokenString = deviceToken.reduce("", {func application(_ application: UIApplication, didRegisterForRemoteNotificationsWithDeviceToken deviceToken: Data) {
let token = deviceToken.reduce("", { 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("Device Token = \(token)")
}

In case of error
出错时
func application(_ application: UIApplication, didRegisterForRemoteNotificationsWithDeviceToken deviceToken: Data) {
let hexString = deviceToken.map { String(format: "%02.2hhx", func application(_ application:UIApplication,didRegisterForRemoteNotificationsWithDeviceToken
devicetoken: Data)
{
let deviceTokenString = deviceToken.hexString
print(deviceTokenString)
}
) }.joined()
print(hexString)
}
