如何更改UISegmentedControl上文本的字体大小？

// 创建UISegmentedControl对象
let segmentedControl = UISegmentedControl(frame: CGRect(x: 50, y: 100, width: 200, height: 30))
segmentedControl.segmentedControlStyle = .plain

// 设置不同状态下的文本属性
let normalTextAttributes = [NSAttributedString.Key.font: UIFont.systemFont(ofSize: 12)]
let selectedTextAttributes = [NSAttributedString.Key.font: UIFont.boldSystemFont(ofSize: 16)]
segmentedControl.setTitleTextAttributes(normalTextAttributes, for: .normal)
segmentedControl.setTitleTextAttributes(selectedTextAttributes, for: .selected)

// 添加选项
segmentedControl.insertSegment(withTitle: "Option 1", at: 0, animated: false)
segmentedControl.insertSegment(withTitle: "Option 2", at: 1, animated: false)

// 将UISegmentedControl添加到视图中
self.view.addSubview(segmentedControl)
