Handoff 切换

NSUserActivity was introduced in iOS 8 to support Handoff. Handoff is the amazing feature that allows you to start an activity on one device and pick up right where you left off on another. NSUserActivity is a lightweight way to capture application state which can be restored later.

切换是神奇的特性,它允许您启动一个活动在一台设备上,从你离开的地方。NSUserActivity捕获应用程序状态是一个轻量级方法后可以恢复。
