ios - 如何在 Swift 中更改 UISegmentedControl 的选定段 tintColor

Question

我想在 Swift 3 中更改 UISegmentedControl 选定段的 tintColor。我在 Objective-c 中搜索了很多答案...
这是我的代码:

class ViewController:UIViewController{

var segment:UISegmentedControl

override func viewDidLoad() {
super.viewDidLoad()

segment.insertSegment(withTitle: "AAA", at: 0, animated: true)
segment.insertSegment(withTitle: "BBB", at: 1, animated: true)
segment.insertSegment(withTitle: "CCC", at: 2, animated: true)

segment.addTarget(self, action: #selector(changeValue), for: .valueChanged)
segment.selectedSegmentIndex = 0

view.addSubview(segment)

}
  func changeValue(sender:AnyObject) {

  //I don't know how to do that change color when segment selected
  // 

}

}

谢谢!

在 ios 13 以上使用下面的代码，

if #available(iOS 13.0, *) {
        segment.selectedSegmentTintColor = .red
} else {
        segment.tintColor = .red
}
