swift weibo 首页框架搭建

1.创建一个根视图  (window) 

2.根视图上添加根控制器  tabbarController

3.创建4个tableviewController  (nav)添加到tabbarController的childController中

 

 

 func addvc(title:String!,imageName:String!,selecterImage:String!){
        var vc = UITableViewController()
        vc.title = title
        UITabBar.appearance().tintColor = UIColor.orangeColor() //修改默认渲染的颜色
        vc.tabBarItem.image = UIImage(named: imageName)?.imageWithRenderingMode(UIImageRenderingMode.AlwaysOriginal)//修改图片默认渲染的颜色
        vc.tabBarItem.selectedImage = UIImage(named: selecterImage)?.imageWithRenderingMode(UIImageRenderingMode.AlwaysOriginal)
        let nav = UINavigationController(rootViewController: vc)
        addChildViewController(nav)
    }
