swift - Facebook边框疑虑

Question

我有一个表格 View ，我希望每个单元格都具有与 Facebook 帖子单元格相同的边框，如下图所示:enter image description here

你能帮我吗？

更新:

我在单元格的awakeFromNib中以这种方式设置图层:

override func awakeFromNib() {

        super.awakeFromNib()
        //self.contentView.backgroundColor = UIColor.red
        self.layer.borderColor = UIColor.gray.cgColor
        self.layer.borderWidth = 1
        self.layer.cornerRadius = 4

    }

但我没有得到同样的 facebook 效果。

Answer 1

像这样设置Tableview单元格

在cellForRowAtIndexpath方法中设置

cell.cardView.setsetCardView()

setCardView函数是

func setCardView()
  {
    let cornerRadius: CGFloat = 10
    let shadowOffsetWidth: Int = 0
    let shadowOffsetHeight: Int = 0
    let shadowColor: UIColor? = UIColor.gray
    let shadowOpacity: Float = 0.5
    layer.cornerRadius = cornerRadius
    layer.masksToBounds = false
    layer.shadowColor = shadowColor?.cgColor
    layer.shadowOffset = CGSize(width: shadowOffsetWidth, height: shadowOffsetHeight);
    layer.shadowOpacity = shadowOpacity
  }
