个人喜好，习惯先自定义UITabBarController,方便管理
1、创建UITabBarController的子类 RootTabBarController
class RootTabBarController: UITabBarController {
override func viewDidLoad() {
super.viewDidLoad()
}
2、在AppDelegate类里指定RootTabBarController为根视图
class AppDelegate: UIResponder, UIApplicationDelegate {
var window: UIWindow?
func application(application: UIApplication, didFinishLaunchingWithOptions launchOptions: [NSObject: AnyObject]?) -> Bool {
self.window = UIWindow(frame: UIScreen.mainScreen().bounds)
self.window?.makeKeyAndVisible()
let root = RootTabBarController()
self.window?.rootViewController=root
// Override point for customization after application launch.
return true
}
3、创建2个空Controller如HomeViewController、SortViewController、OtherViewController
4、在RootTabBarController类里创建tabbar的子控制器
class RootTabBarController: UITabBarController {
override func viewDidLoad() {
super.viewDidLoad()
//创建tabbar的子控制器
self.creatSubViewControllers()
}
func creatSubViewControllers(){
let firstVC = HomeViewController ()
let item1 : UITabBarItem = UITabBarItem (title: "第一页面", image: UIImage(named: "tabbar_home"), selectedImage: UIImage(named: "tabbar_home_selected"))
firstVC.tabBarItem = item1
let secondVC = SortViewController ()
let item2 : UITabBarItem = UITabBarItem (title: "第二页面", image: UIImage(named: "tabbar_sort"), selectedImage: UIImage(named: "tabbar_sort_selected"))
secondVC.tabBarItem = item2
let otherVC = OtherViewController ()
let item3 : UITabBarItem = UITabBarItem (title: "第三页面", image: UIImage(named: "tabbar_other"), selectedImage: UIImage(named: "tabbar_other_selected"))
otherVC.tabBarItem = item3
let tabArray = [firstVC,secondVC,otherVC]
self.viewControllers = tabArray
}
运行后效果
