简单介绍

1. 在AppDelegate的didFinishLaunchingWithOptions中注册

let itemIcon1 = UIApplicationShortcutIcon.init(templateImageName: "AIcon")
let item1 = UIApplicationShortcutItem.init(type: "type1", localizedTitle: "title1", localizedSubtitle: "subTitle1", icon: itemIcon1, userInfo: nil)
        
let itemIcon2 = UIApplicationShortcutIcon.init(templateImageName: "rightIcon")
let item2 = UIApplicationShortcutItem.init(type: "type2", localizedTitle: "title2", localizedSubtitle: "subTitle2", icon: itemIcon2, userInfo: nil)
        
let itemIcon3 = UIApplicationShortcutIcon.init(type: .Add)
let item3 = UIApplicationShortcutItem.init(type: "type3", localizedTitle: "title3", localizedSubtitle: "subTitle3", icon: itemIcon3, userInfo: nil)
        
let itemIcon4 = UIApplicationShortcutIcon.init(type: .Alarm)
let item4 = UIApplicationShortcutItem.init(type: "type4", localizedTitle: "title4", localizedSubtitle: "subTitle4", icon: itemIcon4, userInfo: nil)
        
UIApplication.sharedApplication().shortcutItems = [item1, item2, item3, item4]

效果如图

• 可以自定义图标
• 最多注册4个
• 也可以在infoPlist里注册

2. Item对应的响应事件

func application(application: UIApplication, performActionForShortcutItem shortcutItem: UIApplicationShortcutItem, completionHandler: (Bool) -> Void) {
        switch shortcutItem.type {
        case "":
            balabala~~~
        default:
            balabala~~~
        }
    }

3. 给对应view注册3Dtouch事件

registerForPreviewingWithDelegate(self, sourceView: view)

4.实现UIViewControllerPreviewingDelegate代理

返回弹出的控制器, 通过preferredContentSize设置弹出的大小

func previewingContext(previewingContext: UIViewControllerPreviewing, viewControllerForLocation location: CGPoint) -> UIViewController? {
     return viewControler
}

弹出的控制器后继续重按得回调

func previewingContext(previewingContext: UIViewControllerPreviewing, commitViewController viewControllerToCommit: UIViewController) {
                
}

弹出的控制器后往上滑弹出的选项( 重写previewActionItems )

override func previewActionItems() -> [UIPreviewActionItem] {
    let item1 = UIPreviewAction.init(title: "item1", style: .Destructive) { (_, _) in  ~~blabla~~ }
        
    let item2 = UIPreviewAction.init(title: "item2", style: .Default) { (_, _) in  ~~blabla~~ }
        
    let item3 = UIPreviewAction.init(title: "item3", style: .Selected) { (_, _) in  ~~blabla~~ }

    return [item1, item2, item3]
}

效果图

5. 获取重按力度

override func touchesMoved(touches: Set<UITouch>, withEvent event: UIEvent?) {
    let touch = touches.first ?? UITouch()
    print("\(touch.force)")
}
