iOS学习之UITabBarController

ios 中的uitabbarcontroler 和Android中的tabhost 实现的效果是一样的

//        // 得到屏幕window
//        self.window=UIWindow(frame: UIScreen.mainScreen().bounds)
//        self.window!.backgroundColor=UIColor.whiteColor()
        
        //创建4个界面
        //战绩
        let zj:UIViewController=ZhanjiViewController()
        let navZj=UINavigationController(rootViewController: zj)
        navZj.tabBarItem=UITabBarItem(title: "战绩", image: UIImage(named: "icon_nav_record"), selectedImage: UIImage(named: "icon_nav_record_selected"))
        
        
        //列表
        let lb:UIViewController=LieBiaoViewController()
        let navLb=UINavigationController(rootViewController: lb)
        navLb.tabBarItem=UITabBarItem(title: "列表", image: UIImage(named: "icon_nav_chat"), selectedImage: UIImage(named: "icon_nav_chat_selected"))
        
        //资讯
        let zx:UIViewController=ZiXunViewController()
        let navZx=UINavigationController(rootViewController: zx)
        navZx.tabBarItem=UITabBarItem(title: "资讯", image: UIImage(named: "icon_nav_news"), selectedImage: UIImage(named: "icon_nav_news_selected"))
        //设置
        let sz:UIViewController=SheZhiViewController()
        let navSz=UINavigationController(rootViewController: sz)
        navSz.tabBarItem=UITabBarItem(title: "设置", image: UIImage(named: "icon_nav_tool"), selectedImage: UIImage(named: "icon_nav_tool_selected"))
        
        
        let arr=[navZj,navLb,navZx,navSz]
        //let tabbarController:UITabBarController=UITabBarController()
        self.viewControllers=arr
        //修改tabbar的背景色
        //tabbarController.tabBar.barTintColor=UIColor(red: 19.0/255, green: 32.0/255, blue: 36.0/255, alpha: 1.0)
        self.tabBar.barTintColor=UIColor(patternImage: UIImage(named: "bg_tab_bar"))
        
//        self.window!.rootViewController=tabbarController
//        self.window!.makeKeyAndVisible()
