Question

我在代码中创建了一个UITabBarController，这是我的代码

        var recordsVC = SearchStamViewController()
    recordsVC.tabBarItem = UITabBarItem(title: "Records", image: nil, selectedImage: nil)

    var stationsVC = StationsSeachViewController()
    recordsVC.tabBarItem = UITabBarItem(title: "stations", image: nil, selectedImage: nil)

    var peopleVC = PeopleSearchViewController()
    recordsVC.tabBarItem = UITabBarItem(title: "people", image: nil, selectedImage: nil)



    //self.tabBarController?.setViewControllers([stationsVC , recordsVC], animated: true)

    self.setViewControllers([recordsVC  , peopleVC , stationsVC], animated: true)
    self.selectedIndex = 1
    self.view.backgroundColor = UIColor.whiteColor()

我在我的viewController中的ViewDidLoad中调用了哪个子UITabBarController。我的tabbar没有显示所有tabBar项目标题，laso它以错误的方式显示它们（绿色backGround用于SearchStamViewController而不是SearchStamViewController !!）

怎么了？！

Answer 1

我已更新您的代码

var recordsVC = SearchStamViewController()
recordsVC.tabBarItem = UITabBarItem(title: "Records", image: nil, selectedImage: nil)

var stationsVC = StationsSeachViewController()
stationsVC.tabBarItem = UITabBarItem(title: "stations", image: nil, selectedImage: nil)

var peopleVC = PeopleSearchViewController()
peopleVC.tabBarItem = UITabBarItem(title: "people", image: nil, selectedImage: nil)

self.setViewControllers([recordsVC  , peopleVC , stationsVC], animated: true)
self.selectedIndex = 1
self.view.backgroundColor = UIColor.whiteColor()

Answer 2

我发现了问题，我没有启动新的UITabBarItem 而是

var recordsVC = SearchStamViewController()
recordsVC.tabBarItem.title = "Records"

在代码中初始化UITabbarController
