Swift NavigationController的使用

概述一、创建导航条 func application(application: UIApplication, didFinishLaunchingWithOptions launchOptions: [NSObject: AnyObject]?) -> Bool { // Override point for customization after application launch 一、创建导航条

func application(application: UIApplication,dIDFinishLaunchingWithOptions launchOptions: [NSObject: AnyObject]?) -> Bool {        // OverrIDe point for customization after application launch.        self.window?.backgroundcolor = UIcolor.whitecolor()        let firstVC = FirstVIEwController(nibname:nil,bundle: nil)        let navigation = UINavigationController(rootVIEwController: firstVC)        self.window?.rootVIEwController = navigation;        return true    }

二、导航条上添加按钮

let item = UIbarbuttonItem(Title: "下一个",style: UIbarbuttonItemStyle.Plain,target: self,action: "buttonClick:")        self.navigationItem.rightbarbuttonItem = item

三、跳转到下一个界面

func buttonClick(button:UIbutton) {        let secondVC = SecondVIEwController(nibname:nil,bundle: nil)        self.navigationController?.pushVIEwController(secondVC,animated:true)    }

四、返回到上一个界面

func back() {        self.navigationController?.popVIEwControllerAnimated(true)    }
