我有两个按钮,一个显示分段控件,另一个试图隐藏它。问题是当我单击一个显示它时,它可以工作。但是,当我单击隐藏它时,它不起作用。这是我的代码:
let delayHide = UIAlertAction(title: "Hide Delay", style: .default) { (action) in
self.segmentedHidden = 1
self.setupSegmented()
}
let delayShow = UIAlertAction(title: "Show Delay", style: .default) { (action) in
self.segmentedHidden = 0
self.setupSegmented()
}
这也是我尝试隐藏它的代码:
if (segmentedHidden == 0) {
segmentedControl.isHidden = false
} else {
segmentedControl.isHidden = true
}
我哪里出错了?
答案 0 :(得分:0)
使用以下代码:
@IBAction func buttonTapped(_ sender: UIButton) {
let alert = UIAlertController(title: "Alert", message: "Segment", preferredStyle: .alert)
alert.addAction(UIAlertAction(title: "Show", style: .default, handler: { (alertAction) in
self.showHideSegmentControl(isHidden: false)
}))
alert.addAction(UIAlertAction(title: "hide", style: .default, handler: { (alertAction) in
self.showHideSegmentControl(isHidden: true)
}))
self.present(alert, animated: true, completion: nil)
}
func showHideSegmentControl(isHidden: Bool) {
segmentedControl.isHidden = isHidden
}
