ios - UITableViewCells之间的间距

我正在 swift 创建一个ios应用程序，并希望在像Facebook(图波纹管)这样的单元之间增加间距。

我在帖子中使用自定义 Nib 。我知道要使用UITableViewController。我认为我会使用分隔符样式，但没有达到效果。我闲逛了几个小时，无法 swift 找到一个有意义的教程!有人可以解释一下他们是如何使用swift在应用程序中完成的吗？谢谢!

最佳答案

这是我的解决方案，其结果是:(基于Jorge Casariego的回答)

override func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell {
    let cell = tableView.dequeueReusableCellWithIdentifier("cell", forIndexPath: indexPath) as! CustomApplicationCell

    cell.contentView.backgroundColor = UIColor.clear

    let whiteRoundedView : UIView = UIView(frame: CGRectMake(10, 8, self.view.frame.size.width - 20, 149))

    whiteRoundedView.layer.backgroundColor = CGColorCreate(CGColorSpaceCreateDeviceRGB(), [1.0, 1.0, 1.0, 0.8])
    whiteRoundedView.layer.masksToBounds = false
    whiteRoundedView.layer.cornerRadius = 2.0
    whiteRoundedView.layer.shadowOffset = CGSizeMake(-1, 1)
    whiteRoundedView.layer.shadowOpacity = 0.2

    cell.contentView.addSubview(whiteRoundedView)
    cell.contentView.sendSubviewToBack(whiteRoundedView)

    return cell
}

桌子排高:165点

页眉节高度，页脚节高度:10点





编辑Swift 3语法:

override func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
    let cell = tableView.dequeueReusableCell(withIdentifier: "cell", for: indexPath) as! CustomApplicationCell

    cell.contentView.backgroundColor = UIColor.clear

    let whiteRoundedView : UIView = UIView(frame: CGRect(x: 10, y: 8, width: self.view.frame.size.width - 20, height: 120))

    whiteRoundedView.layer.backgroundColor = CGColor(colorSpace: CGColorSpaceCreateDeviceRGB(), components: [1.0, 1.0, 1.0, 0.9])
    whiteRoundedView.layer.masksToBounds = false
    whiteRoundedView.layer.cornerRadius = 2.0
    whiteRoundedView.layer.shadowOffset = CGSize(width: -1, height: 1)
    whiteRoundedView.layer.shadowOpacity = 0.2

    cell.contentView.addSubview(whiteRoundedView)
    cell.contentView.sendSubview(toBack: whiteRoundedView)

    return cell
}

创建 CardView.swift

@IBDesignable
class CardView: UIView {

    @IBInspectable var cornerRadius: CGFloat = 2

    @IBInspectable var shadowOffsetWidth: Int = 0
    @IBInspectable var shadowOffsetHeight: Int = 3
    @IBInspectable var shadowColor: UIColor? = .black
    @IBInspectable var shadowOpacity: Float = 0.5

    override func layoutSubviews() {
        layer.cornerRadius = cornerRadius
        let shadowPath = UIBezierPath(roundedRect: bounds, cornerRadius: cornerRadius)

        layer.masksToBounds = false
        layer.shadowColor = shadowColor?.cgColor
        layer.shadowOffset = CGSize(width: shadowOffsetWidth, height: shadowOffsetHeight)
        layer.shadowOpacity = shadowOpacity
        layer.shadowPath = shadowPath.cgPath
    }
}

现在只需将CardView类添加到您的UIView中。
