To obtain a Device Token, you need to implement the following steps in your application:
Request user authorization in the application: You need to request user authorization to allow the application to send remote notifications. This can be done by using UNUserNotificationCenter (User Notifications framework). You can display an authorization popup to the user, asking them to allow notifications.
Register for remote notifications: Once the user is authorized, you can use the UIApplication.shared.registerForRemoteNotifications() method to register for remote notifications. This will trigger the system to send the device token to your application.
Implement the proxy method to obtain the device token: In the application's proxy class, implement the following method to obtain the device token:
swift
Copy code
func application(_ application: UIApplication, didRegisterForRemoteNotificationsWithDeviceToken deviceToken: Data) { // Convert deviceToken to string format for sending to server let tokenString = deviceToken.map { String(format: “%02.2hhx”, $0) }.joined()
// 将 deviceToken 发送给服务器
// 在此处添加您的代码逻辑，将 tokenString 发送给服务器保存
}
func application(_ application: UIApplication, didFailToRegisterForRemoteNotificationsWithError error: Error) { // Failed to register for remote notifications, handling errors } The didRegisterForRemoteNotificationsWithDeviceToken method will be called when the device token is successfully obtained. In this method you can convert the device token to string format and send it to your server to save and use.
If registering for remote notifications fails, the system calls the didFailToRegisterForRemoteNotificationsWithError method, where you can handle the error condition.

| Send the device token to the server: In the didRegisterForRemoteNotificationsWithDeviceToken method, you need to write code to send the device token to your server. You can send the device token to the server using a network request or other communication methods that suit you. |
On the server side, you can save the device token and use it to send push notifications to specific devices.
Note that device tokens are associated with specific applications and devices, and may change when an application is uninstalled or the device is reset. Therefore, you need to periodically update the device token on the server to ensure that push notifications can be sent to the target device correctly.
The above are the basic steps to get device token in iOS application. The exact implementation may vary depending on the programming language and development framework you use. You can refer to Apple's official documentation and developer resources for more details about remote notification registration and device token acquisition.
To request user authorization in your application to send remote notifications, you need to follow these steps:
Import the UserNotifications framework: In your application's code, you first need to import the UserNotifications framework in order to use the notification-related classes and methods.
Request authorization: You can call the following methods to request user authorization when the application starts or at an appropriate time:
swift
Copy code
UNUserNotificationCenter.current().requestAuthorization(options: [.alert, .badge, .sound]) { (granted, error) in
// authorization result processing
if granted { // user authorized push notification } else { / / The user rejected the push notification or the authorization failed } } In the above code, the options parameter specifies the notification permissions you need to request, including pop-up notifications, app icon badges, and sounds. Make the appropriate configuration according to your needs.
Handle authorization results: When the authorization request is complete, the callback closure you provide will be invoked. In that callback, you can handle the user's authorization result. If the granted parameter is true, it means that the user has authorized the push notification; if the granted parameter is false, it means that the user has rejected the push notification or the authorization failed. You can perform related operations as needed.
Note that you need to ensure that the relevant permission descriptions are configured in your app's Info.plist file so that the correct authorization prompt is shown to the user when authorization is requested. Here is an example configuration:
xml
Copy code
NSRemoteNotificationUsageDescription
We need to send notifications to communicate important information to you.
In the example above, the NSRemoteNotificationUsageDescription key specifies the description displayed to the user when permission for push notifications is requested. You can customize this description according to your application needs.
By following the steps above, your application will be able to request the user's authorization to send remote notifications, and act accordingly based on the user's choice.
Please note that user authorization is part of user privacy, and you need to follow Apple's privacy policy and best practices, and properly handle user data and privacy when using remote notifications.
