如何在swift中一次选中一个复选框？

let checkboxButton = UIButton(type: .system)
checkboxButton.setImage(UIImage(named: "unchecked"), for: .normal)
checkboxButton.setImage(UIImage(named: "checked"), for: .selected)
checkboxButton.isSelected = false

checkboxButton.addTarget(self, action: #selector(checkboxTapped(_:)), for: .touchUpInside)

@objc func checkboxTapped(_ sender: UIButton) {
    sender.isSelected = !sender.isSelected
}

@objc func checkboxTapped(_ sender: UIButton) {
    sender.isSelected = !sender.isSelected
    
    if sender.isSelected {
        // 复选框被选中时的操作
        // ...
    } else {
        // 复选框未选中时的操作
        // ...
    }
}
