应用入口（AppDelegate.swift）

import UIKit

@UIApplicationMain
class 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 UIKit

        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)
