我正在尝试将多个SegmentedControls加载到Xcode上的一个ViewController中。下面是按钮。
当我点击其中一个按钮时,我想要加载SegmentedControl。
这些SegmentedControls将加载到ViewController上。有没有办法让这种情况发生?
我目前的代码如下:
@IBAction func action(_ sender: Any) {
//let url = URL(string: sender.accessibilityIdentifier!)!
let alertController = UIAlertController(title: (sender as AnyObject).accessibilityLabel, message: (sender as AnyObject).accessibilityHint, preferredStyle: .actionSheet)
let HSAction = UIAlertAction(title: "Upper Building", style: .default) { action in
DispatchQueue.main.async {
self.performSegue(withIdentifier: "one", sender: nil)
}
//UIApplication.shared.open(url, options: [:], completionHandler: nil)
}
alertController.addAction(HSAction)
}
答案 0 :(得分:0)
移动到另一个视图控制器后,您可以使用多个按钮创建segmentedcontrol,如下所示。
segmentedControl = UISegmentedControl (items: ["First","Second","Third"])
segmentedControl.frame = CGRectMake(60, 250,200, 30)
segmentedControl.selectedSegmentIndex = 0
segmentedControl.addTarget(self, action: "segmentedControlAction:", forControlEvents: .ValueChanged)
self.view.addSubview(segmentedControl)
