当didRegisterForRemoteNotificationsWithDeviceToken叫什么名字？ [英] When is didRegisterForRemoteNotificationsWithDeviceToken called?

问题描述

有很多关于didRegisterForRemoteNotificationsWithDeviceToken问题，但他们都回避一个很直接的问题，我似乎无法找到一个确切的答案。

对于正确设置了通知，在其他方面并有适当的网络连接的应用程序：当didRegisterForRemoteNotificationsWithDeviceToken叫什么名字？一些可能的选择可能是：

1. 每次应用程序启动


2. 初始提示用户只有在接受推送通知


3. 别的东西吗？

解决方案

应用程序代表将呼吁的远程通知注册成功的方法，你在你的UIApplication调用此方法后：

  

（无效）registerForRemoteNotificationTypes：（UIRemoteNotificationType）类型

据：<一href=\"http://developer.apple.com/library/ios/#DOCUMENTATION/UIKit/Reference/UIApplication_Class/Reference/Reference.html\">http://developer.apple.com/library/ios/#DOCUMENTATION/UIKit/Reference/UIApplication_Class/Reference/Reference.html

  

当您发送该消息，该设备发起与苹果推送服务的登记程序。如果成功，应用程序委托接收在应用程序的设备令牌：didRegisterForRemoteNotificationsWithDeviceToken：方式; didFailToRegisterForRemoteNotificationsWithError：方法，如果注册不成功，委托通过的应用程序通知。如果应用程序代理接收设备令牌，它应该与它的供应商连接，并通过它的令牌。

现在，为了进一步阐述，通常一个应用程序将调用 registerForRemoteNotificationTypes 在 didFinishLaunchingWithOptions：（NSDictionary的*）launchOptions 在应用程序委托。因此，在应用：didRegisterForRemoteNotificationsWithDeviceToken ，然后通常是启动该应用程序后调用的瞬间

编辑：应用程序：didRegisterForRemoteNotificationsWithDeviceToken仍然得到后的第一个要求subsequents登记

There are a lot of questions about didRegisterForRemoteNotificationsWithDeviceToken but they all sidestep a very direct question which I cannot seem to find an exact answer to.

For an app which is properly set up for notifications in all other ways and has proper network connectivity: when is didRegisterForRemoteNotificationsWithDeviceToken called? Some possible choices might be:

1. Every time the app starts
2. Only after the initial prompt to the user to accept push notifications
3. Something else?

解决方案

The application delegate will call the method upon successful registration of remote notification after you call this method in your UIApplication:

(void)registerForRemoteNotificationTypes:(UIRemoteNotificationType)types

According to: http://developer.apple.com/library/ios/#DOCUMENTATION/UIKit/Reference/UIApplication_Class/Reference/Reference.html

When you send this message, the device initiates the registration process with Apple Push Service. If it succeeds, the application delegate receives a device token in the application:didRegisterForRemoteNotificationsWithDeviceToken: method; if registration doesn’t succeed, the delegate is informed via the application:didFailToRegisterForRemoteNotificationsWithError: method. If the application delegate receives a device token, it should connect with its provider and pass it the token.

Now, to elaborate further, normally an app will call the registerForRemoteNotificationTypes in your didFinishLaunchingWithOptions:(NSDictionary *)launchOptions in your application delegate. And therefore, the application:didRegisterForRemoteNotificationsWithDeviceToken is then usually called moments after the launch of the application.

Edit: The application:didRegisterForRemoteNotificationsWithDeviceToken still gets called for subsequents registration after the first.
