速览的界面
你可以在
Apple Watch
中测试一下速览。轻点速览后，应用会启动，然后立即进入听写
模式，让你创建笔记。
可能需要自己动手在
iPhone
中的
Watch
应用里把速览添加到手表中。
如果想在模拟器中测试速览，在方案选择区中选择“
Glance - Watch
”。如果目标是模拟
器，模拟的手表会显示速览。

本章对前面开发的
iOS
应用做了扩展，支持了
Apple Watch
。我们构建了一个简单的
watchOS
应用，允许用户在
Apple Watch
中查看和新建笔记。为此，我们使用了构建
watchOS
应用所需的
WatchKit
框架，以及手表和手机之间的通信系统。我们还为这个
watchOS
系统添加了
Handoff
功能，这样用户可以在多台设备中处理相同的信息。
