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

例子在swift 3..

Crease a single view application add tableview in view controller add a customcell for tablview cell view controller code is bellow like class ViewController: UIViewController,UITableViewDelegate,UITableViewDataSource { @IBOutlet weak var tableView: UITableView! var arraytable = [[String:Any]]() override func viewDidLoad() { super.viewDidLoad() arraytable = [ ["title":"About Us","detail":"RA-InfoTech Ltd -A Joint Venture IT Company formed by Bank Asia Ltd"], ["title":"Contact","detail":"Bengal Center (4th & 6th Floor), 28, Topkhana Road, Dhaka - 1000, Bangladesh"] ] tableView.delegate = self tableView.dataSource = self //For Auto Resize Table View Cell; tableView.estimatedRowHeight = 44 tableView.rowHeight = UITableViewAutomaticDimension //Detault Background clear tableView.backgroundColor = UIColor.clear } func numberOfSections(in tableView: UITableView) -> Int { return arraytable.count } func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int { return 1 } // Set the spacing between sections func tableView(_ tableView: UITableView, heightForHeaderInSection section: Int) -> CGFloat { return 10 } // Make the background color show through func tableView(_ tableView: UITableView, viewForHeaderInSection section: Int) -> UIView? { let headerView = UIView() headerView.backgroundColor = UIColor.clear return headerView } func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell { let cell = tableView.dequeueReusableCell(withIdentifier: "cell")! as! CustomCell cell.tv_title.text = arraytable[indexPath.section]["title"] as! String? cell.tv_details.text = arraytable[indexPath.section]["detail"] as! String? //label height dynamically increase cell.tv_details.numberOfLines = 0 //For bottom border to tv_title; let frame = cell.tv_title.frame let bottomLayer = CALayer() bottomLayer.frame = CGRect(x: 0, y: frame.height - 1, width: frame.width, height: 1) bottomLayer.backgroundColor = UIColor.black.cgColor cell.tv_title.layer.addSublayer(bottomLayer) //borderColor,borderWidth, cornerRadius cell.backgroundColor = UIColor.lightGray cell.layer.borderColor = UIColor.red.cgColor cell.layer.borderWidth = 1 cell.layer.cornerRadius = 8 cell.clipsToBounds = true return cell } } Download full source to Github : link https://github.com/enamul95/CustomSectionTable

你可以像这样简单地在代码中使用constraint:

class viewCell : UITableViewCell 
{

@IBOutlet weak var container: UIView!



func setShape() {
    self.container.backgroundColor = .blue
    self.container.layer.cornerRadius = 20
    container.translatesAutoresizingMaskIntoConstraints = false
    self.container.widthAnchor.constraint(equalTo:contentView.widthAnchor , constant: -40).isActive = true
           self.container.heightAnchor.constraint(equalTo: contentView.heightAnchor,constant: -20).isActive = true
           self.container.centerXAnchor.constraint(equalTo: contentView.centerXAnchor).isActive = true
           self.container.centerYAnchor.constraint(equalTo: contentView.centerYAnchor).isActive = true

    }
}

添加子视图(容器)并在其中放入其他元素是很重要的。

我认为这是最干净的解决方案:

class MyTableViewCell: UITableViewCell {
    override func awakeFromNib() {
        super.awakeFromNib()
        layoutMargins = UIEdgeInsetsMake(8, 0, 8, 0)
    }
}

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?

我的情况是我使用自定义UIView viewForHeader在节也hightforheader在节返回常量高度说40，问题是当没有数据时，所有的头视图被彼此触摸。所以我想在没有数据的部分之间留出空间，所以我通过将“tableview style”平面改为“Group”来固定。这对我很有效。
