ios - 返回第四个 View 时分段控件颜色不显示

Question

我的分段控件在首次加载时显示我想要的紫色文本，但是当我按回导航栏然后返回 View 时，颜色消失了。我已经在viewDidLoad和viewWillAppear中尝试过。

   override func viewDidLoad() {

    mySegmentedControl.tintColor = UIColor.black
    mySegmentedControl.setFontSize(fontSize: 14)

    UISegmentedControl.appearance().setTitleTextAttributes([NSForegroundColorAttributeName: UIColor.purple], for: UIControlState.selected)

    super.viewDidLoad()


}

Answer 1

我认为您应该为每个 UISegmentedControl 设置 setTitleTextAttributes，而不是为所有 UISegmentedControl 设置。

override func viewDidLoad() {
    super.viewDidLoad()

    mySegmentedControl.tintColor = UIColor.black
    mySegmentedControl.setFontSize(fontSize: 14)
    mySegmentedControl.setTitleTextAttributes([NSForegroundColorAttributeName: UIColor.purple], for: .selected)
}
