我尝试设置 TitleTextAttributes.

UITabBarItem.appearance().setTitleTextAttributes([NSForegroundColorAttributeName: UIColor(red: 22.0/255.0, green: 209.0/255.0, blue: 237.0/255.0, alpha: 1.0),NSFontAttributeName: UIFont(name: "SFUIDisplay-Regular", size: 36.0)!], forState:UIControlState.Focused)

推荐答案

我不确定我是否理解您的问题，但我在开发 Apple TV 应用程序时遇到了一些类似的问题.

I'm not sure if I understood your question but I faced some similar issue when developing an Apple TV app.

我想要做的是更改标签栏项目的字体颜色.

What I wanted to do is to change the font color for the tab bar items.

这就是我所做的.首先，我创建了一个 UITabBarController 子类，并将其添加到故事板上的控制器中.然后我在 -(void)viewDidLoad

This is what I ended doing. First I made a UITabBarController subclass and liked it to their controller on the storyboard. Then I added this code in the -(void)viewDidLoad

for(UITabBarItem * item in self.tabBar.items) {
    [item setTitleTextAttributes:@{NSForegroundColorAttributeName : [UIColor darkGrayColor]} forState:UIControlStateNormal];
    [item setTitleTextAttributes:@{NSForegroundColorAttributeName : [UIColor blueColor]} forState:UIControlStateFocused];
}

而且一切正常.
