初次接触swift,写下demo和笔记
每一个项目的框架构成,几乎都是UINavigationController+UITabBarController,那么究竟swift如何搭建起框架。
- 效果图:
第一步:新建几个控制器,根据项目模块决定

let vc1:UIViewController = HomeViewController();
let nav1 = UINavigationController(rootViewController:vc1);
nav1.tabBarItem = UITabBarItem(title:"首页",image:UIImage(named:"icon_home_menu01"),selectedImage:UIImage(named:"icon_home_menu01_after"))
let vc2:UIViewController = MarketViewController();
let nav2 = UINavigationController(rootViewController:vc2);
nav2.tabBarItem = UITabBarItem(title:"营销",image:UIImage(named:"icon_home_menu02"),selectedImage:UIImage(named:"icon_home_menu02_after"))
let vc3:UIViewController = FundViewController();
let nav3 = UINavigationController(rootViewController:vc3);
nav3.tabBarItem = UITabBarItem(title:"发现",image:UIImage(named:"icon_home_menu03"),selectedImage:UIImage(named:"icon_home_menu03_after"))
nav3.tabBarItem.badgeValue = "2";
let vc4:UIViewController = MineViewController();
let nav4 = UINavigationController(rootViewController:vc4);
nav4.tabBarItem = UITabBarItem(title:"我的",image:UIImage(named:"icon_home_menu04"),selectedImage:UIImage(named:"icon_home_menu04_after"))
nav4.tabBarItem.selectedImage = UIImage(named:"icon_home_menu02_after");
第三步:设置好导航和tabBar,然后让tabVC做跟控制器即可
let arr = [nav1,nav2,nav3,nav4];
let tab:UITabBarController = UITabBarController();
tab.viewControllers = arr;
tab.tabBar.barStyle = .blackOpaque
tab.selectedIndex = 4; //默认选中
self.window?.rootViewController = tab;
