Question

我正在尝试自定义UITabBarController。我已将其嵌入UIViewController中，我还为此UITabBarController创建了一个类。

override func viewDidLoad() {
    super.viewDidLoad()

    //custom tab bar
    self.tabBar.barTintColor = UIColor(red: 0.0/255.0, green: 102.0/255.0, blue: 153.0/255.0, alpha: 1)
    self.tabBar.tintColor = UIColor(red: 171.0/255.0, green: 203.0/255.0, blue: 61.0/255.0, alpha: 1)
    self.tabBarItem.setTitleTextAttributes([NSForegroundColorAttributeName: UIColor.whiteColor()], forState:UIControlState.Normal)
    self.tabBarItem.setTitleTextAttributes([NSForegroundColorAttributeName: UIColor.whiteColor()], forState:UIControlState.Disabled)

    for item in self.tabBar.items as [UITabBarItem]
    {
        item.image = item.selectedImage.imageWithRenderingMode(UIImageRenderingMode.AlwaysOriginal)
    }


    // Do any additional setup after loading the view.
}

setTitleTextAttributes对标签栏项目没有任何影响。有人可以帮我找出错误的位置吗？

以下是在这种情况下仍然可以放在UITabBarController中的代码：

override func viewDidLoad() {
super.viewDidLoad()

//custom tab bar
self.tabBar.barTintColor = UIColor(red: 0.0/255.0, green: 102.0/255.0, blue: 153.0/255.0, alpha: 1)
self.tabBar.tintColor = UIColor(red: 171.0/255.0, green: 203.0/255.0, blue: 61.0/255.0, alpha: 1)

for item in self.tabBar.items as [UITabBarItem]
{
    item.image = item.selectedImage.imageWithRenderingMode(UIImageRenderingMode.AlwaysOriginal)
item.setTitleTextAttributes([NSForegroundColorAttributeName: UIColor.whiteColor()], forState:UIControlState.Normal)
    item.setTitleTextAttributes([NSForegroundColorAttributeName: UIColor.whiteColor()], forState:UIControlState.Disabled)
    item.setTitleTextAttributes([NSForegroundColorAttributeName: UIColor(red: 171.0/255.0, green: 203.0/255.0, blue: 61.0/255.0, alpha: 1)], forState:UIControlState.Selected)
}
}

标签栏项目属于各个子视图控制器，因此您需要更改这些控制器中的属性，而不是标签栏控制器。

当在swift中取消选择UITabBarItem时，setTitleTextAttributes不起作用
