iOS推送通知-application：didRegisterForRemoteNotificationsWithDeviceToken：是否在主线程中执行？
[英]iOS push notifications - does application:didRegisterForRemoteNotificationsWithDeviceToken: execute in main thread?
问题描述
I am wondering if an iOS app delegate's application:didRegisterForRemoteNotificationsWithDeviceToken: method executes in the main thread? 
我想知道iOS应用程序委托的application:didRegisterForRemoteNotificationsWithDeviceToken:方法是否在主线程中执行？
Ultimately I would like to know whether it is safe to put UI code in this method and if I should keep blocking code (like network interactions) out of it. 最终，我想知道将UI代码放入此方法是否安全，是否应该阻止代码（例如网络交互）。
In general, are delegate methods executed in the main thread? 通常，委托方法是否在主线程中执行？

The application delegate methods such as: 应用程序委托方法，例如：
application:didRegisterForRemoteNotificationsWithDeviceToken:
are executed on the main thread. 在主线程上执行。
If you want your application to be responsive for the user you should but blocking code in a background thread. 如果希望您的应用程序对用户响应，则应在后台线程中阻止代码。
It is safe and recommended to execute UI code on the main thread. 建议在主线程上执行UI代码是安全的。
