It is not possible to leave an app in the background when choosing a Home screen quick action. 选择主屏幕快速操作时， 无法将应用程序保留在后台。
From the documentation of UIApplicationShortcutItem : 从UIApplicationShortcutItem的文档中：
When a user chooses one of your Home screen quick actions, the system launches or resumes your app and
UIKitcalls theapplication(_:performActionFor:completionHandler:)method in your app delegate.UIKit在您的应用程序委托中调用application(_:performActionFor:completionHandler:)方法。
