如何从UISegmentedControl获取字符串字体

let segmentedControl = UISegmentedControl(items: ["Option 1", "Option 2", "Option 3"])

segmentedControl.addTarget(self, action: #selector(segmentedControlValueChanged(_:)), for: .valueChanged)

@objc func segmentedControlValueChanged(_ sender: UISegmentedControl) {
    let selectedIndex = sender.selectedSegmentIndex
    // 在这里处理选中段落索引的变化
}

@objc func segmentedControlValueChanged(_ sender: UISegmentedControl) {
    let selectedIndex = sender.selectedSegmentIndex
    
    var font: UIFont?
    switch selectedIndex {
    case 0:
        font = UIFont.systemFont(ofSize: 14)
    case 1:
        font = UIFont.boldSystemFont(ofSize: 16)
    case 2:
        font = UIFont.italicSystemFont(ofSize: 18)
    default:
        break
    }
    
    if let font = font {
        let fontName = font.fontName
        // 在这里可以使用获取到的字体名称进行后续操作
    }
}
