无论如何检查应用程序何时会被暂停?
Is there anyway to check when an app will be suspended?
是否有 iOS 应用程序暂停时间的通用时间(即当它退出后台模式并终止时)。
不,没有任何可能知道,据此:
Suspended: ...The system moves apps to this state automatically and does not notify them before doing so...
背景
The app is in the background and executing code. Most apps enter this
state briefly on their way to being suspended. However, an app that
requests extra execution time may remain in this state for a period of
time. In addition, an app being launched directly into the background
enters this state instead of the inactive state. For information about
how to execute code while in the background, see Background Execution.
已暂停
The app is in the background but is not executing code. The system
moves apps to this state automatically and does not notify them before
doing so. While suspended, an app remains in memory but does not
execute any code. When a low-memory condition occurs, the system may
purge suspended apps without notice to make more space for the
foreground app.
