应用入口（AppDelegate.swift）

import UIKit@UIApplicationMainclass AppDelegate: UIResponder, UIApplicationDelegate {    var window: UIWindow?    func application(application: UIApplication, didFinishLaunchingWithOptions launchOptions: [NSObject: AnyObject]?) -> Bool {        window = UIWindow(frame: UIScreen.mainScreen().bounds)        window?.backgroundColor = UIColor.whiteColor()                let viewController = DMViewController()        let nav = UINavigationController(rootViewController: viewController)        nav.navigationBarHidden = true        window?.rootViewController = nav                window?.makeKeyAndVisible()                        return true    }}

分组控制器（DMViewController.swift）

import UIKitclass DMViewController: UIViewController , UITableViewDelegate , UITableViewDataSource{    @IBOutlet weak var tableView: UITableView!    var dataArr = NSMutableArray()    var selectSection = NSInteger()    override func viewDidLoad() {        super.viewDidLoad()        tableView.delegate = self        tableView.dataSource = self        tableView.separatorStyle = UITableViewCellSeparatorStyle.None        selectSection = -1                //数据模拟        for(var i = 0 ; i < 10 ; i++ ){            let dataDict = NSMutableDictionary()            //整型->字符串            var title = String(i)            title.appendContentsOf("_section")            //浮点->字符串            let double = 20.12            let doubleString = NSString(format: "%f", double)                        dataDict.setObject(title, forKey: "title")            dataDict.setObject(doubleString, forKey: "double")            dataDict.setObject(String(i), forKey: "id")                        let tempMarr = NSMutableArray()            for(var j = 0 ; j < 5 ; j++){                let sectionDict = NSMutableDictionary()                var titlej = String(j)                titlej.appendContentsOf("_row")                let doublej = 41.32                let doubleStringj = NSString(format: "%f", doublej)                sectionDict.setObject(titlej, forKey: "title")                sectionDict.setObject(doubleStringj, forKey: "double")                sectionDict.setObject(String(j), forKey: "id")                tempMarr.addObject(sectionDict)            }            dataDict.setObject(tempMarr, forKey: "section")            dataArr.addObject(dataDict)        }    }    //组数    func numberOfSectionsInTableView(tableView: UITableView) -> Int {        return dataArr.count    }        //每组cell数    func tableView(tableView: UITableView, numberOfRowsInSection section: Int) -> Int {        if(selectSection == -1){            return 1        }else{            if(selectSection == section){                return dataArr.objectAtIndex(selectSection).objectForKey("section")!.count + 1            }else{                return 1            }        }    }        //赋值    func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell {        /*默认Cell        let cell:UITableViewCell = UITableViewCell(style: UITableViewCellStyle.Subtitle, reuseIdentifier:"cell");        cell.textLabel!.text = "test1"        */               //自定义cell        let cellIdentifier = "DMTableViewCell"        self.tableView!.registerNib(UINib(nibName: "DMTableViewCell", bundle:nil), forCellReuseIdentifier: cellIdentifier)                let cell : DMTableViewCell = tableView.dequeueReusableCellWithIdentifier(cellIdentifier, forIndexPath: indexPath) as! DMTableViewCell        cell.selectionStyle = UITableViewCellSelectionStyle.None                if(selectSection == indexPath.section){            let selectDict = dataArr.objectAtIndex(indexPath.section)            let sectionArr = selectDict.objectForKey("section")            if(indexPath.row == 0){                cell.assignmentFromDictionary(dataArr.objectAtIndex(indexPath.section) as! NSDictionary ,andMark: 0)            }else{                cell.assignmentFromDictionary(sectionArr!.objectAtIndex(indexPath.row-1) as! NSDictionary ,andMark: 1)            }        }else{            cell.assignmentFromDictionary(dataArr.objectAtIndex(indexPath.section) as! NSDictionary , andMark: 0)        }               return cell    }        //cell高度    func tableView(tableView: UITableView, heightForRowAtIndexPath indexPath: NSIndexPath) -> CGFloat {        return 60.0    }        //选中cell    func tableView(tableView: UITableView, didSelectRowAtIndexPath indexPath: NSIndexPath) {        if(selectSection == indexPath.section && indexPath.row == 0){            selectSection = -1        }else{            selectSection = indexPath.section        }        tableView.reloadData()    }}

分组Cell（DMTableViewCell.swift）

import UIKitclass DMTableViewCell: UITableViewCell {    @IBOutlet weak var leftImagview: UIImageView!        @IBOutlet weak var idLab: UILabel!        @IBOutlet weak var titleLab: UILabel!        var dataDict = NSDictionary()        @IBOutlet weak var sectionView: UIView!        @IBOutlet weak var rowView: UIView!        @IBOutlet weak var rowImgview: UIImageView!        @IBOutlet weak var rowIdLab: UILabel!        @IBOutlet weak var rowTitleLab: UILabel!            override func awakeFromNib() {        super.awakeFromNib()    }    override func setSelected(selected: Bool, animated: Bool) {        super.setSelected(selected, animated: animated)    }        //赋值    func assignmentFromDictionary(valueDict : NSDictionary, andMark:NSInteger){        dataDict = valueDict                        if(andMark == 1){            sectionView.hidden = true            rowView.hidden = false            rowIdLab.text = valueDict.valueForKey("id") as? String            rowTitleLab.text = valueDict.objectForKey("title") as? String        }else{            sectionView.hidden = false            rowView.hidden = true            idLab.text = valueDict.valueForKey("id") as? String            titleLab.text = valueDict.objectForKey("title") as? String        }    }}
