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）
