不需要使用一堆不同的部分。其他的答案使用框架insets和CGRect和图层…等等等等。不太好;使用自动布局和自定义UITableViewCell。在那个UITableViewCell中，不是在contentView中查看你的内容，而是创建一个新的containerView(一个UIView)，在contentView中查看容器视图，然后在容器视图中查看所有视图。

现在要创建空格，只需编辑容器视图的布局边距，如下所示:

class CustomTableViewCell: UITableViewCell {
    let containerView = UIView()
    let imageView = UIImageView()

    required init?(coder aDecoder: NSCoder) {super.init(coder: aDecoder)}

    override init(style: UITableViewCell.CellStyle, reuseIdentifier: String?) {
        super.init(style: style, reuseIdentifier: reuseIdentifier)

        containerView.translatesAutoResizingMaskIntoConstraints = false
        imageView.translatesAutoResizingMaskIntoConstraints = false
        contentView.addSubview(containerView)
        containerView.addSubview(imageView)

        contentView.layoutMargins = UIEdgeInsets(top: 15, left: 3, bottom: 15, right: 3)
        containerView.layoutMargins = UIEdgeInsets(top: 15, left: 17, bottom: 15, right: 17) // It isn't really necessary unless you've got an extremely complex table view cell. Otherwise, you could just write e.g. containerView.topAnchor

        let cg = contentView.layoutMarginsGuide
        let lg = containerView.layoutMarginsGuide
        NSLayoutConstraint.activate([
            containerView.topAnchor.constraint(equalTo: cg.topAnchor),
            containerView.leadingAnchor.constraint(equalTo: cg.leadingAnchor),
            containerView.trailingAnchor.constraint(equalTo: cg.trailingAnchor),
            containerView.bottomAnchor.constraint(equalTo: cg.bottomAnchor),
            imageView.topAnchor.constraint(equalTo: lg.topAnchor),
            imageView.leadingAnchor.constraint(equalTo: lg.leadingAnchor),
            imageView.trailingAnchor.constraint(equalTo: lg.trailingAnchor),
            imageView.bottomAnchor.constraint(equalTo: lg.bottomAnchor)
        ])
    }
}

这篇文章很有帮助，它和其他答案差不多，但是总结和简洁

其中，他只将它们应用于左侧和右侧，但UIEdgeInsetsMake初始化允许为所有四个点添加填充。

func UIEdgeInsetsMake(_ top: CGFloat, _ left: CGFloat, _ bottom: CGFloat, _ right: CGFloat) -> UIEdgeInsets Description Creates an edge inset for a button or view. An inset is a margin around a rectangle. Positive values represent margins closer to the center of the rectangle, while negative values represent margins further from the center. Parameters top: The inset at the top of an object. left: The inset on the left of an object bottom: The inset on the bottom of an object. right: The inset on the right of an object. Returns An inset for a button or view

注意，UIEdgeInsets也可以用来实现同样的效果。

Xcode 9.3/Swift 4

我可以想到三种方法:

Create a custom table cell that lays out the view of the entire cell in the manner that you desire Instead of adding the image to the image view, clear the subviews of the image view, create a custom view that adds an UIImageView for the image and another view, perhaps a simple UIView that provides the desired spacing, and add it as a subview of the image view. I want to suggest that you manipulate the UIImageView directly to set a fixed size/padding, but I'm nowhere near Xcode so I can't confirm whether/how this would work.

明白吗?

我遇到了麻烦，让它与背景颜色和附属视图一起在单元格中工作。最后不得不:

1)使用带有背景颜色的UIView设置单元格的背景视图属性。

let view = UIView()
view.backgroundColor = UIColor.white
self.backgroundView = view

2)在layoutSubviews中重新定位这个视图，添加间距的想法

override func layoutSubviews() {
    super.layoutSubviews()
    backgroundView?.frame = backgroundView?.frame.inset(by: UIEdgeInsets(top: 2, left: 0, bottom: 0, right: 0)) ?? CGRect.zero
}

我在Swift 4中是这样解决的。

我创建了UITableViewCell的扩展，并包括以下代码:

override open var frame: CGRect {
    get {
        return super.frame
    }
    set (newFrame) {
        var frame =  newFrame
        frame.origin.y += 10
        frame.origin.x += 10
        frame.size.height -= 15
        frame.size.width -= 2 * 10
        super.frame = frame
    }
}

override open func awakeFromNib() {
    super.awakeFromNib()
    layer.cornerRadius = 15
    layer.masksToBounds = false
}

我希望这对你有所帮助。

使用UITableViewDelegate, highightforrowatindexpath并返回行高。

 (CGFloat)tableView:(UITableView *)tableView heightForRowAtIndexPath:(NSIndexPath *)indexPath {
 return 100.0f ;
}
