ios会在特定时间后终止在后台运行的应用吗？ [英] Will ios terminate the app running in background after a specific time?
问题描述
我在我的应用程序中使用核心位置框架，我在UIBackgroundMode中设置位置字符串或在Xcode 4.2中设置所需的后台模式，以便从 didUpdateToLocation 方法获取更新的位置当应用程序在后台运行时，通过点击核心位置框架的 didUpdateToLocation 方法中的特定链接，将此更新的位置发送到服务器。
I am using core location framework inside my application and I set the location string in UIBackgroundMode or Required background modes(in Xcode 4.2) for getting the updated location from didUpdateToLocation method when app is running in background and also sending this updated location to server by hitting the specific link inside didUpdateToLocation method of core location framework.
我的问题是，应用程序会在后台运行一段时间后终止吗？
My question is that will the app be terminated after some time when running in background or not?
推荐答案
否，没有特定的时间为此定义。但应用程序肯定会根据某些参数终止 - 电池耗尽，内存占用问题等。
No, there is no specific time defined for this.But app will definitely terminate based upon certain parameter - battery drain, memory footprint issue etc.
在开发者文档中明确提到 - 系统将暂停的应用程序保留在内存中尽可能长时间，只有当可用内存量变低时才将其删除。内存中的剩余内容意味着随后启动pp更快。
In developer documentation it is clearly mentioned - "The system keeps suspended apps in memory for as long as possible, removing them only when the amount of free memory gets low. Remaining in memory means that subsequent launches of your app are much faster."
