后台应用刷新检查，以编程方式为整个设备以及iOS 7中的每个特定应用启用和禁用
问题描述：
我们可以通过设置手动检查整个设备以及iOS 7中每个特定应用程序的后台应用程序刷新.
We can check Background App Refresh for whole device and for each particular application in iOS 7 manually from settings.
在iOS 7中有什么方法可以通过编程方式做到这一点吗?
Is there any way to do it programmatically in iOS 7?
答
简短的答案是:您不能检查每个应用程序的后台刷新"设置是由于应用程序沙箱导致的.应用程序可能会如何检查用户是否修改了自己的后台刷新"设置.
The short answer is no you can't check to see what every app's Background Refresh setting is due to application sandboxing. An application may how ever check to see if the user has modified the Background Refresh setting for itself.
