Apps on iOS are sandboxed and can not directly communicate with other apps directly. iOS 上的应用程序是沙盒的，不能直接与其他应用程序直接通信。 There are some API's in the iOS SDK which allows some interaction, mostly audio, share of items. iOS SDK 中有一些 API 允许一些交互，主要是音频，项目共享。

Apple does not expose to you app if an other app is launched, so checking that an other is launched is not possible.如果启动了其他应用程序，Apple 不会向您公开应用程序，因此无法检查其他应用程序是否已启动。
