我也有同感。起初，我试着换到分组课，但对我来说，最后比我最初想象的更头疼，所以我一直在寻找替代方案。为了继续使用行(并且不干扰你访问模型数据的方式)，下面是我使用蒙版的方法:

func tableView(_ tableView: UITableView, willDisplay cell: UITableViewCell, forRowAt indexPath: IndexPath)
{
    let verticalPadding: CGFloat = 8

    let maskLayer = CALayer()
    maskLayer.cornerRadius = 10    //if you want round edges
    maskLayer.backgroundColor = UIColor.black.cgColor
    maskLayer.frame = CGRect(x: cell.bounds.origin.x, y: cell.bounds.origin.y, width: cell.bounds.width, height: cell.bounds.height).insetBy(dx: 0, dy: verticalPadding/2)
    cell.layer.mask = maskLayer
}

All you have left to do is make the cell's height bigger by the same value as your desired verticalPadding, and then modify your inner layout so that any views that had spacing to the edges of the cell have that same spacing increased by verticalPadding/2. Minor downside: you get verticalPadding/2 padding on both the top and bottom of the tableView, but you can quickly fix this by setting tableView.contentInset.bottom = -verticalPadding/2 and tableView.contentInset.top = -verticalPadding/2. Hope this helps somebody!

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。

如果您还没有使用节页眉(或页脚)，您可以使用它们为表单元格添加任意间距。与其创建一个有n行的section，不如创建一个有n个section，每个section都有一行的表。

实现tableView: hightforheaderinsection:方法来控制间距。

你可能还想实现tableView:viewForHeaderInSection:来控制空格的样子。

为了增加行之间的间距，将使用第二个原型单元格。

在第二个原型单元格中添加一个不同的单元格标识符，然后添加一个空视图，并将其边缘约束到单元格的边缘，然后将emptyView的颜色设置为“clear”。

然后在代码中:

import UIKit

class YourViewController: UIViewController, UITableViewDelegate, UITableViewDataSource {
        
        @IBOutlet weak var yourTableView: UITableView!
        
        let yourArray = ["data1", "data2", "data3" /* so on */ ]

        let emptyTransparentRowHeight: CGFloat = 10
        
        override func viewDidLoad() {
            super.viewDidLoad()
    
            yourTableView.dataSource = self
            yourTableView.delegate = self
        }
            

        func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
            return (yourArray.count * 2)
        }
        
        func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
            
            guard indexPath.row % 2 == 0,
                let usableCell = tableView.dequeueReusableCell(withIdentifier: "Your First Cell Prototype Identifier") as? YourTableViewCellSubClass
            else {
                
                return tableView.dequeueReusableCell(withIdentifier: "The Second and Empty Cell Prototype Identifier")!
            }
      
            usableCell.Label?.text = yourArray[indexPath.row/2]
            
            return usableCell
    
        }
        
        func tableView(_ tableView: UITableView, heightForRowAt indexPath: IndexPath) -> CGFloat {
            if indexPath.row % 2 == 0 {
                return tableView.rowHeight
            }
            
            return self.emptyTransparentRowHeight
        }
        
    }

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?
