Question

我需要使用分段控件来更改视图。在以下示例中，我将两个视图容器放在同一位置：

隐藏第二个容器，每次使用分段控件时我都会通过代码显示它。（虽然它也没有表现出来。）

import UIKit

class ViewController: UIViewController {

    @IBOutlet weak var container1: UIView!
    @IBOutlet weak var container2: UIView!

    override func viewDidLoad() {
        super.viewDidLoad()
    }

    override func didReceiveMemoryWarning() {
        super.didReceiveMemoryWarning()
    }

    @IBAction func showComponent(_ sender: Any) {
        if (sender as AnyObject).selectedSegmentIndex == 0 {
            UIView.animate(withDuration: 0.5, animations: {
                self.container1.alpha = 1
                self.container2.alpha = 0
            })
        } else {
            UIView.animate(withDuration: 0.5, animations: {
                self.container1.alpha = 0
                self.container2.alpha = 1
            })
        }
    }

}

你知道其他任何方法吗？

有没有办法自定义SegmentedControl，就好像它是TAB一样？

如果你能给我一个项目，那会很棒。但如果您可以尝试按照下一步操作，也许不需要它。
我会以不同的方式做到这一点。在你的VC中添加UIView。称之为容器视图。然后在xib（笔尖）中创建2个单独的视图here和here。然后将这2个视图添加到容器视图中： view.addSubsire(view1)和view.addSubsire(view2)
然后，您只需检查分段控件并显示所需的视图。
不要忘记UI调试。使用这个惊人的功能：link

实施可能需要一些时间，但这些是您在任何情况下都需要了解的基础知识，因此它肯定会有用。

希望它有所帮助！祝你好运！
