3D Touch

// 定义一个枚举类型

enum Shortcut: String {

    case openBlue = "OpenBlue"

}

// APP正在运行时，下面的方法会响应3D Touch操作

func application(_ application: UIApplication, performActionFor shortcutItem: UIApplicationShortcutItem, completionHandler: @escaping (Bool) -> Void) {

        completionHandler(handleQuickAction(shortcutItem))

    }

// guard

 guard let touch = touches.first else {

            return

        }

// 判断3D Touch是否可用

 if traitCollection.forceTouchCapability == UIForceTouchCapability.available {}
