搜索控制器，圆角不起作用

Question

这个视图的顺序是这样的

 -View Controller

      -Fake shadow view

           -Container view

               -Search Bar

在正常状态下，圆角可以正常工作，但是当我点击它时，会有一些阴影。当我在上面输入一些东西时，视图就会变成矩形

试试这个 IBDesignable 课程，并从故事板上画出圆角

import Foundation
@IBDesignable class customView: UIView {
    @IBInspectable var cornerRadius: CGFloat = 0 {
        didSet {
            layer.cornerRadius = cornerRadius
        }
    }

    @IBInspectable var borderWidth: CGFloat = 0 {
        didSet {
            layer.borderWidth = borderWidth
        }
    }

    @IBInspectable var borderColor: UIColor = UIColor.gray {
        didSet {
            layer.borderColor = borderColor.cgColor
        }
    }

    @IBInspectable var shadowColor: UIColor = UIColor.gray {
        didSet {
            layer.shadowColor = shadowColor.cgColor
        }
    }

    @IBInspectable var shadowOpacity: Float = 1.0 {
        didSet {
            layer.shadowOpacity = shadowOpacity
        }
    }

    @IBInspectable var shadowRadius: CGFloat = 1.0 {
        didSet {
            layer.shadowRadius = shadowRadius
        }
    }

    @IBInspectable var masksToBounds: Bool = true {
        didSet {
            layer.masksToBounds = masksToBounds
        }
    }

    @IBInspectable var shadowOffset: CGSize = CGSize(width: 12, height: 12) {
        didSet {
            layer.shadowOffset = shadowOffset
        }
    }
}
