之前记录过OC版实现3D Touch功能的小小演示，最近无事整整swift，也弄个swift版的3D Touoch。。。

上代码。

一、3D Touch重按主屏icon出现快捷标签有两种添加方式：

1.静态添加，在工程中的info.plist文件中添加，这种方式添加的标签安装后就能显示

2.动态添加，通过代码动态添加快速入口。这种方式添加的标签，必须先运行一次App才会出现。

func application(application: UIApplication, didFinishLaunchingWithOptions launchOptions: [NSObject: AnyObject]?) -> Bool {        // Override point for customization after application launch.        self.window?.frame = UIScreen.mainScreen().bounds        self.window?.makeKeyAndVisible()                UIApplication.sharedApplication().statusBarStyle = UIStatusBarStyle.LightContent                self.window = UIWindow(frame: UIScreen.mainScreen().bounds)        self.window?.makeKeyWindow()                self.configShortCutItems()                self.window?.rootViewController = McUITabBarController()                return true    }

func configShortCutItems()    {        //动态添加方式        let icon1 = UIApplicationShortcutIcon(type: .Play)        let item1 = UIMutableApplicationShortcutItem(type: "777", localizedTitle: "标题", localizedSubtitle: "副标题", icon: icon1, userInfo: nil)        let icon2 = UIApplicationShortcutIcon(type: .Add)        let item2 = UIMutableApplicationShortcutItem(type: "888", localizedTitle: "标题", localizedSubtitle: "副标题", icon: icon2, userInfo: nil)        let icon3 = UIApplicationShortcutIcon(templateImageName: "shareIcon")        let item3 = UIMutableApplicationShortcutItem(type: "999", localizedTitle: "自定义图片", localizedSubtitle: nil, icon: icon3, userInfo: nil)        UIApplication.sharedApplication().shortcutItems = [item1,item2,item3]                    }

需要说明一点，主屏呼出的快捷标签，静态和动态添加的共只能有四个。

3D Touch在appdelegate.swift代理方法：

//pragma mark - 3D Touch    func application(application: UIApplication, performActionForShortcutItem shortcutItem: UIApplicationShortcutItem, completionHandler: (Bool) -> Void) {        switch shortcutItem.type {        case "666":            print("静态添加")        case "777":            print("动态代码添加一")        case "888":            print("动态代码添加二")        case "999":            print("自定义图片")        default:            print("")        }    }

至此，通过重按主屏触发3D Touch 呼出快捷标签和点击分别响应操作已集成完毕！

二、3D Touch 的peek和pop功能在tableView上的简单实现

话不多说，直接上代码

1.peek预览

DDDTouchVC.swift

3D Touch的代理控制器需要实现 UIViewControllerPreviewingDelegate 协议

import UIKitclass DDDTouchVC: McBaseViewController,UITableViewDataSource,UITableViewDelegate,UIViewControllerPreviewingDelegate {    static let cellIdentifer = "myCell"    var tableView: UITableView?    var isCan3DTouch = true    var itemArray : Array = [Dictionary<String,String>]()        override func viewDidLoad() {        super.viewDidLoad()        // Do any additional setup after loading the view.        self.setCustomTitle("3D Touch")        self.initData()        self.initSubView()        if traitCollection.forceTouchCapability == UIForceTouchCapability.Available {                        self.isCan3DTouch = true        }        else {            self.isCan3DTouch = false        }    }    func initData()    {        let dic1 = ["m":"http://a.hiphotos.baidu.com/image/h%3D360/sign=1698b41ebb389b5027ffe654b535e5f1/a686c9177f3e6709e974ebff39c79f3df8dc55bd.jpg"]        let dic2 = ["mm":"http://b.hiphotos.baidu.com/image/h%3D360/sign=ff34dff8bd389b5027ffe654b537e5f1/a686c9177f3e670900d880193fc79f3df9dc5578.jpg"]        let dic3 = ["mmm":"http://a.hiphotos.baidu.com/image/h%3D360/sign=f527ab2f4b540923b5696578a259d1dc/dcc451da81cb39dbce6b325ad2160924ab183016.jpg"]        let dic4 = ["mmmm":"http://d.hiphotos.baidu.com/image/h%3D360/sign=81d5d22779f40ad10ae4c1e5672d1151/d439b6003af33a8762fee505c45c10385343b51a.jpg"]        let dic5 = ["mmmmm":"http://d.hiphotos.baidu.com/image/h%3D200/sign=8d3a52a04ded2e73e3e9812cb701a16d/f7246b600c33874450b89258560fd9f9d72aa091.jpg"]        let dic6 = ["mmmmmm":"http://h.hiphotos.baidu.com/image/h%3D360/sign=e53dee25d5ca7bcb627bc1298e086b3f/a2cc7cd98d1001e9ae32c3e9ba0e7bec55e797ce.jpg"]        let dic7 = ["mmmmm":"http://g.hiphotos.baidu.com/image/h%3D360/sign=8cb0e6191a178a82d13c79a6c602737f/6c224f4a20a446230761b9b79c22720e0df3d7bf.jpg"]        let dic8 = ["mmmm":"http://a.hiphotos.baidu.com/image/h%3D360/sign=80285822f9f2b211fb2e8348fa806511/bd315c6034a85edf1da1c0724b540923dd5475b5.jpg"]        let dic9 = ["mmm":"http://e.hiphotos.baidu.com/image/h%3D360/sign=708629f379cb0a469a228d3f5b62f63e/7dd98d1001e939015d4a463779ec54e736d1966b.jpg"]        let dic10 = ["mm":"http://h.hiphotos.baidu.com/image/h%3D360/sign=95102c30bc096b639e1958563c338733/3801213fb80e7beccbb1e8fe2d2eb9389b506b42.jpg"]        let dic11 = ["m":"http://a.hiphotos.baidu.com/image/h%3D360/sign=cbd227bf8e5494ee9822091f1df5e0e1/c2cec3fdfc039245ee84470f8594a4c27d1e25f8.jpg"]        let dic12 = ["mm":"http://e.hiphotos.baidu.com/image/h%3D360/sign=87824d652adda3cc14e4be2631e83905/b03533fa828ba61e64671cd54534970a314e59bb.jpg"]        itemArray.append(dic1)        itemArray.append(dic2)        itemArray.append(dic3)        itemArray.append(dic4)        itemArray.append(dic5)        itemArray.append(dic6)        itemArray.append(dic7)        itemArray.append(dic8)        itemArray.append(dic9)        itemArray.append(dic10)        itemArray.append(dic11)        itemArray.append(dic12)    }        func initSubView()    {        self.tableView = UITableView(frame: CGRectMake(0, 0, McConstant.screenWidth, McConstant.screenHeight), style: UITableViewStyle.Plain)        self.tableView?.backgroundColor = UIColor.clearColor()        self.tableView?.dataSource = self        self.tableView?.delegate = self        self.view.addSubview(self.tableView!)    }        override func didReceiveMemoryWarning() {        super.didReceiveMemoryWarning()        // Dispose of any resources that can be recreated.    }        func tableView(tableView: UITableView, numberOfRowsInSection section: Int) -> Int {        return itemArray.count    }        func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell {        var cell = tableView.dequeueReusableCellWithIdentifier(ModuleOneVC.cellIdentifer)        if cell == nil {            cell = UITableViewCell(style: UITableViewCellStyle.Default, reuseIdentifier: ModuleOneVC.cellIdentifer)            if self.isCan3DTouch {                //注册3D Touch                registerForPreviewingWithDelegate(self, sourceView: (cell?.contentView)!)            }        }        let dic = itemArray[indexPath.row]        cell?.textLabel?.text = Array(dic.keys)[0]        cell?.textLabel?.textColor = UIColor.blackColor()        cell?.backgroundColor = UIColor.clearColor()        return cell!    }        func tableView(tableView: UITableView, heightForRowAtIndexPath indexPath: NSIndexPath) -> CGFloat {        return 50    }        func tableView(tableView: UITableView, didSelectRowAtIndexPath indexPath: NSIndexPath) {        tableView.deselectRowAtIndexPath(indexPath, animated: true)        let dic = itemArray[indexPath.row]        self.navigationController?.pushViewController(DDDTouchPeekVC(imgUrl: Array(dic.values)[0]), animated: true)            }    //mark -UIViewControllerPreviewingDelegate 3D Touch代理方法    func previewingContext(previewingContext: UIViewControllerPreviewing, viewControllerForLocation location: CGPoint) -> UIViewController?

2.pop界面控制器

DDDTouchPeekVC.swift

import UIKitclass DDDTouchPeekVC: McBaseViewController {    var etag:String?    var potoView:UIImageView?    var imageUrl:String?    init(imgUrl:String){        super.init(nibName: nil, bundle: nil)        self.imageUrl = imgUrl    }        required init?(coder aDecoder: NSCoder) {        fatalError("init(coder:) has not been implemented")    }    override func viewDidLoad() {        super.viewDidLoad()        // Do any additional setup after loading the view.        self.setCustomTitle("3D TouchPeekVC")        self.initSubView()        self.initData()    }    override func didReceiveMemoryWarning() {        super.didReceiveMemoryWarning()        // Dispose of any resources that can be recreated.    }        func initData()    {        let url = NSURL.init(string: imageUrl!)        let request = NSURLRequest(URL: url!)        let task = NSURLSession.sharedSession().dataTaskWithRequest(request) { (dataa, response, error) in            dispatch_async(dispatch_get_main_queue(), {                //                self.potoView?.image = UIImage(data: dataa!)            })        }        task.resume()            }    func initSubView(){        let titleView = UILabel(frame: CGRectMake(0, 0, McConstant.screenWidth, 64))        titleView.backgroundColor = UIColor(red: 52/255, green: 222/255, blue: 136/255, alpha: 1).colorWithAlphaComponent(0.8)        titleView.textAlignment = NSTextAlignment.Center        titleView.text = "PeekView"        self.view.addSubview(titleView)                self.potoView = UIImageView(frame: CGRect(x: 0, y: 64, width: McConstant.screenWidth, height: McConstant.screenHeight-60))        self.potoView?.contentMode = UIViewContentMode.ScaleToFill        self.view.addSubview(self.potoView!)    }    //pragma mark - 底部预览界面选项    override func previewActionItems() -> [UIPreviewActionItem] {        //        let action1 = UIPreviewAction(title: "点赞", style: .Default) { (action, previewViewController) in            //        }        let action2 = UIPreviewAction(title: "评论", style: .Default) { (action, previewViewController) in            //        }        let action3 = UIPreviewAction(title: "嘿嘿", style: .Default) { (action, previewViewController) in            //        }        let action4 = UIPreviewAction(title: "呵呵", style: .Default) { (action, previewViewController) in            //        }        let actionItems = [action1,action2,action3,action4]        return actionItems            }}

至此，3D Touch功能在tableView上列表的简单功能就完成了，这边是peek 、pop展示的是加载一张百度连接的图片。匆忙而就，写得不详细，如有错误，谅解。。。
