使用分段控件隐藏swift中的元素

let segmentedControl = UISegmentedControl(items: ["Option 1", "Option 2"])
segmentedControl.frame = CGRect(x: 20, y: 50, width: 200, height: 30)
segmentedControl.selectedSegmentIndex = 0
view.addSubview(segmentedControl)

let label = UILabel(frame: CGRect(x: 20, y: 100, width: 200, height: 30))
label.text = "Hidden Element"
view.addSubview(label)

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

@objc func segmentedControlValueChanged(_ sender: UISegmentedControl) {
    if sender.selectedSegmentIndex == 0 {
        label.isHidden = true
    } else {
        label.isHidden = false
    }
}
