使用分段控制更改视图

如何解决《使用分段控制更改视图》经验,为你挑选了1个好方法。

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:

在此输入图像描述

第二个容器是隐藏的,每次我使用分段控件时我都会通过代码显示它.(虽然它也没有显示出来.)

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,好像它是一个TAB?
