我想定期将用户当前的纬度和经度发布到服务器。应用程序在前台运行时发布正常。但是如果应用程序在后台运行，有什么办法可以做到这一点？
最佳答案
据我所知，您不应在 applicationDidEnterBackground 中调用任何耗时的函数，因为该应用会在短时间后暂停。
来自 Apple 的 IOS 编程指南
Most applications that enter the background state are moved to the suspended state shortly thereafter. While in this state, the application does not execute any code and may be removed from memory at any time. Applications that provide specific services to the user can request background execution time in order to provide those services.
