使用节而不是行 每个section应该返回一行 使用indexPath分配单元格数据。Section，而不是row 实现UITableView委托方法hightforheader并返回你想要的间距

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!

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
    }

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。
