IOS 3D Touch功能

IOS 3D touch功能

• IOS9之后苹果增加了3d touch支持，也就是用力按压主屏幕按钮来调出快速操作的菜单

添加方式

• 静态添加

  • 配置info.plist文件添加UIApplicationShortcutItems数组

  <key>UIApplicationShortcutItems</key>
    <array>
        <dict>
            <key>UIApplicationShortcutItemIconFile</key>
            <string>open-favorites</string>
            <key>UIApplicationShortcutItemIconType</key>
            <string>open-favorites</string>
            <key>UIApplicationShortcutItemTitle</key>
            <string>Title</string>
            <key>UIApplicationShortcutItemType</key>
            <string>com.mycompany.myapp.openfavorites</string>
            <key>UIApplicationShortcutItemSubtitle</key>
            <string>Subtitle</string>
            <key>UIApplicationShortcutItemUserInfo</key>
            <dict>
                <key>key1</key>
                <string>value1</string>
            </dict>
        </dict>
    </array>
  

  其中UIApplicationShortcutItemTitle和UIApplicationShortcutItemType是必填的，对应的是此快捷方式的标题和唯一标识符

  其他几个参数可选

  UIApplicationShortcutItemSubtitle是副标题

  UIApplicationShortcutItemIconFile是配置自己工程里面的图标

  UIApplicationShortcutItemIconType是配置系统自带的图标

  UIApplicationShortcutItemUserInfo是配置额外的可能需要的字典参数

• 动态添加

  在didFinishLaunchingWithOptions代码中添加

      func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey: Any]?) -> Bool {
        let dynamicIcon1 = UIApplicationShortcutIcon(systemImageName: "play")
        let dynamicItem1 = UIApplicationShortcutItem(type: "play", localizedTitle: "播放", localizedSubtitle: "播放喜欢的内容", icon: dynamicIcon1, userInfo: nil)
        
        let dynamicIcon2 = UIApplicationShortcutIcon(systemImageName: "message")
        let dynamicItem2 = UIApplicationShortcutItem(type: "message", localizedTitle: "消息", localizedSubtitle: "发送消息", icon: dynamicIcon2, userInfo: nil)
        
        UIApplication.shared.shortcutItems = [dynamicItem1, dynamicItem2]
    }
  

  具体展现为

  

  添加的顺序是先静态后动态，且最多添加4个，多出的不会显示

逻辑处理

• 在AppDelegate中的performActionFor方法中处理逻辑

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

shortcutItem: UIApplicationShortcutItem就带有所有的信息
