ios - 当我的应用程序被终止时，如何将数据发布到服务器？

Question

当我的应用程序被终止时，如何将数据发布到服务器？我使用 NSURLSession 类。我尝试在 applicationWillTerminate 运行时发布数据，但它不起作用。

Answer 1

applicationWillTerminate 不适用于此类任务，您可能没有足够的时间执行与服务器相关的操作。

Refer this apple doc

This method lets your app know that it is about to be terminated and purged from memory entirely. You should use this method to perform any final clean-up tasks for your app, such as freeing shared resources, saving user data, and invalidating timers. Your implementation of this method has approximately five seconds to perform any tasks and return. If the method does not return before time expires, the system may kill the process altogether.
