ios：我想在tableview的顶部和底部添加边框

Question

我在 viewdidload() 中应用了以下代码，但使用此代码边框已到达但它随表格内容滚动。我想在顶部和底部修复边框。

这里我的代码是->

    let topBorder = CAShapeLayer()
    let topPath = UIBezierPath()
    topPath.move(to: CGPoint(x: 0, y: 0))
    topPath.addLine(to: CGPoint(x: tblFilter.frame.width, y: 0))
    topBorder.path = topPath.cgPath
    topBorder.strokeColor = UIColor.red.cgColor
    topBorder.lineWidth = 1.0
    topBorder.fillColor = UIColor.red.cgColor
    tblFilter.layer.addSublayer(topBorder)

    let bottomBorder = CAShapeLayer()
    let bottomPath = UIBezierPath()
    bottomPath.move(to: CGPoint(x: 0, y: tblFilter.frame.height))
    bottomPath.addLine(to: CGPoint(x: tblFilter.frame.width, y: tblFilter.frame.height))
    bottomBorder.path = bottomPath.cgPath
    bottomBorder.strokeColor = UIColor.red.cgColor
    bottomBorder.lineWidth = 1.0
    bottomBorder.fillColor = UIColor.red.cgColor
    tblFilter.layer.addSublayer(bottomBorder)

给我建议，谢谢

我正在使用以下方法向任何视图添加边框。如果对你有帮助，请看一看。

//MARK: - Add Border to View -
func addTopBorderWithColor(_ objView : UIView, color: UIColor, width: CGFloat) {
let border = CALayer()
border.backgroundColor = color.cgColor
border.frame = CGRect(x: 0, y: 0, width: objView.frame.size.width, height: width)
objView.layer.addSublayer(border)
}

func addBottomBorderWithColor(_ objView : UIView, color: UIColor, width: CGFloat) {
let border = CALayer()
border.backgroundColor = color.cgColor
border.frame = CGRect(x: 0, y: objView.frame.size.height - width, width: objView.frame.size.width, height: width)
objView.layer.addSublayer(border)
}
