我认为最直接的解决方案，如果你只是寻找一点空间，可能最便宜的将是简单地设置单元格边框颜色为您的表格背景颜色，然后设置边框宽度，以获得所需的结果!

    cell.layer.borderColor = blueColor.CGColor
    cell.layer.borderWidth = 3

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。

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

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?

我需要做相同的概念，让UITableCells之间有一个“空间”。因为你不能在单元格之间添加空间，你可以通过操纵UITableView的单元格高度来伪造它，然后添加一个UIView到你的单元格的contentView。这是我在另一个测试项目中模拟的一个原型的屏幕截图:

下面是一些代码(注意:为了演示目的，有很多硬编码的值)

首先，我需要设置highightforrowatindexpath以允许UITableViewCell上的不同高度。

- (CGFloat)tableView:(UITableView *)tableView heightForRowAtIndexPath:(NSIndexPath *)indexPath
{

    NSString *text = [self.newsArray  objectAtIndex:[indexPath row]];
    if ([text isEqual:@"December 2012"])
    {
        return 25.0;
    }

    return 80.0;
}

接下来，我想操纵UITableViewCells的外观和感觉，所以我在willDisplayCell:(NewsUITableViewCell *)cell forRowAtIndexPath:(NSIndexPath *)indexPath方法中做到这一点。

- (void)tableView:(UITableView *)tableView willDisplayCell:(NewsUITableViewCell *)cell forRowAtIndexPath:(NSIndexPath *)indexPath
{
    if (cell.IsMonth)
    {
        UIImageView *av = [[UIImageView alloc] initWithFrame:CGRectMake(20, 20, 20, 20)];
        av.backgroundColor = [UIColor clearColor];
        av.opaque = NO;
        av.image = [UIImage imageNamed:@"month-bar-bkgd.png"];
        UILabel *monthTextLabel = [[UILabel alloc] init];
        CGFloat font = 11.0f;
        monthTextLabel.font = [BVFont HelveticaNeue:&font];

        cell.backgroundView = av;
        cell.textLabel.font = [BVFont HelveticaNeue:&font];
        cell.textLabel.textColor = [BVFont WebGrey];
    }


    if (indexPath.row != 0)
    {
        cell.contentView.backgroundColor = [UIColor clearColor];
        UIView *whiteRoundedCornerView = [[UIView alloc] initWithFrame:CGRectMake(10,10,300,70)];
        whiteRoundedCornerView.backgroundColor = [UIColor whiteColor];
        whiteRoundedCornerView.layer.masksToBounds = NO;
        whiteRoundedCornerView.layer.cornerRadius = 3.0;
        whiteRoundedCornerView.layer.shadowOffset = CGSizeMake(-1, 1);
        whiteRoundedCornerView.layer.shadowOpacity = 0.5;
        [cell.contentView addSubview:whiteRoundedCornerView];
        [cell.contentView sendSubviewToBack:whiteRoundedCornerView];

    }
}

注意，我使我的whiteRoundedCornerView高度70.0，这就是模拟空间的原因，因为单元格的高度实际上是80.0，但我的contentView是70.0，这给了它外观。

也许还有其他更好的方法，但这就是我找到的方法。我希望它能帮助到其他人。

这是实际的解决方案

使用节而不是行因为每一行都有一个节所以你可以给页眉留出空间节脚这是代码，把它粘贴到你的视图控制器类中，在这里你创建tableview outlet

如果你想要顶部间距使用heightForHeaderInSection 如果你想要底部间距，只需使用heightForFooterInSection如下所示

复制粘贴即可

func tableView(_ tableView: UITableView, heightForFooterInSection section: Int) -> CGFloat {
    return 20
}

func tableView(_ tableView: UITableView, viewForFooterInSection section: Int) -> UIView? {
    let v = UIView()
    v.backgroundColor = UIColor.clear
    return v
}

    func numberOfSections(in tableView: UITableView) -> Int {
        return 10
    }

    func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
        return 1
    }
