我有3个不同的数组，分别是cricketMatchArray、soccerMatchArray和tennisMatchArray。我在3个表视图中显示这3个数组数据，单击标题后，表视图将展开。面临的问题是表高度不会根据数据计数而变化。
This output is I'm getting and I want remove that red mark space
例如：* 如果具有数据的板球和网球阵列以及足球阵列为空，则足球桌高度不变 *

我想根据数组计数动态更改表的高度。

例如，如果具有数据的板球和网球阵列和足球阵列为空，则足球桌高度应为0。
下面是我的代码。

class AllLiveMatchesViewController: UIViewController {
    
    @IBOutlet weak var cricketTableView: UITableView!
    @IBOutlet weak var soccerTableView: UITableView!
    @IBOutlet weak var tennisTableView: UITableView!
    
    var selectedIndx = -1
    var thereIsCellTapped = false
    
    var cricketMatchArray = [LiveMatchesData]()
    var soccerMatchArray = [LiveMatchesData]()
    var tennisMatchArray = [LiveMatchesData]()

    override func viewDidLoad() {
        super.viewDidLoad()

        cricketTableView.dataSource = self
        cricketTableView.delegate = self
        cricketTableView.separatorStyle = .none
        cricketTableView.tableFooterView = UIView()
        
        soccerTableView.dataSource = self
        soccerTableView.delegate = self
        soccerTableView.separatorStyle = .none
        soccerTableView.tableFooterView = UIView()
        
        tennisTableView.dataSource = self
        tennisTableView.delegate = self

有人能帮我一下吗。

问题是您复制了代码，但没有复制属性：

if tableView == cricketTableView
    {
        // This is the problem :
        // only one selectedIndx and one thereIsCellTapped but 3 tables, so it give the same result
        // for the 3 tables
        if (self.selectedIndx != section) && thereIsCellTapped{
            return 0
        }
        else if (self.selectedIndx == section) && thereIsCellTapped{
            
            return 20
        }
        else
        {
            return 0
        }
        
        
    }

您在以下方面遇到此问题：

  • 行高度
  • 截面中的脚部高度
  • 在节中查看页脚
  • 查看节中的标题
  • 并且可以在didSelectRowAt中

作为一个好奇的问题-为什么你有3个单独的表视图，而不是一个与部分？
在这种情况下，不需要在一个ViewController中具有3个不同的UITableView。
通过控制截面中的单元格数量，我们可以简化视图的逻辑。
点击标题应控制其他节的“隐藏”逻辑（=将给定节中的行数设置为零）。

您可以将Single TableView与包含StackView的单元格一起使用，方法是将其设置为Top、Leading、Trailing和Bottom。节中的行数应为3。这意味着现在有三个单元格填充每个单元格中的数组。heightForRowAt应为UITableView.automaticDimension
