I found this and the problem is that the answers on that question didn't pan out (I also tested them first) and also that it is over a year old.
我发现了这个问题，问题是这个问题的答案没有成功（我先测试过它们），而且还有一年多了。
I've used the solution here to fetch the list of all running processes, but not of the struct kinfo_proc attributes seem to give any useful in detecting which app is currently visible to the user.
我在这里使用了解决方案来获取所有正在运行的进程的列表，但结构kinfo_proc属性似乎没有给出任何有用的检测用户当前可见的应用程序。
Basically:
基本上：
I am trying to find out which app is currently visible (and open) to the user on iOS devices. It must work on stock devices (non-jailbroken) and no need to worry about the app store.
我试图在iOS设备上找出用户当前可见（和打开）的应用程序。它必须适用于库存设备（非越狱），无需担心应用程序商店。
Edit: I am looking at the private APIs now, but cannot seem to determine how my app could be notified (or inquire) about a new application being brought to the front.
编辑：我现在正在查看私有API，但似乎无法确定我的应用程序如何被通知（或查询）有关新应用程序被带到前面。
Thank you
