Question

由于未捕获的异常终止应用＆＃39; NSInternalInconsistencyException＆＃39;，原因：＆＃39;尝试删除第100部分，但更新前只有7个部分＆＃39; ***首先抛出调用堆栈：

我试图制作可折叠的TableView WithAnimation.From Header确实点击了它将调用切换部分的方法。我的工作基于它是选择还是不选择bool值。

class ExploreLocallyVc: UIViewController {
var headerViewMain = HeaderView()
@IBOutlet weak var tableView: UITableView?
var ArrayOfCollapsable : [Int:Bool]? = [:]
var prevIousSelection : Int? = 100
override func viewDidLoad() {
    super.viewDidLoad()

    tableView?.estimatedRowHeight = 80
    tableView?.rowHeight = UITableViewAutomaticDimension
    tableView?.sectionHeaderHeight = 60
    tableView?.separatorStyle = .none

}
}

extension ExploreLocallyVc:UITableViewDelegate,UITableViewDataSource
{
    func numberOfSections(in tableView: UITableView) -> Int
{
    return 7
}

func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int
{
    if (ArrayOfCollapsable?[section] == true) {
        print("yes")
       return 4
    }
    else
    {
    print("No")
       return 0
    }
    }
func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell
{
    let cell = tableView.dequeueReusableCell(withIdentifier: "q", for: indexPath)
     cell.textLabel?.text = "\(indexPath.row)"
    return cell
}
func tableView(_ tableView: UITableView, viewForHeaderInSection section: Int) -> UIView?
{
    headerViewMain = (Bundle.main.loadNibNamed("HeaderView", owner: self, options: nil)![0] as? HeaderView)!
    headerViewMain.titleLabel?.text = "\(section)"
    if (ArrayOfCollapsable?[section] == true) {
       headerViewMain.arrowLabel?.transform = CGAffineTransform(rotationAngle: CGFloat.pi)
    }
    headerViewMain.section = section
    headerViewMain.delegate = self

    return headerViewMain
}
}

extension ExploreLocallyVc:HeaderViewDelegate
{
func toggleSection(header: HeaderView, section: Int)
{

    if (ArrayOfCollapsable?[section] == true) {
        print("yes")
       ArrayOfCollapsable?[section] = false
    }
    else
    {
        print("No")
        ArrayOfCollapsable?[section] = true
        ArrayOfCollapsable?.updateValue(false, forKey: prevIousSelection!)
    }
    tableView?.reloadSections(NSIndexSet(index: section) as IndexSet, with: .automatic)
    prevIousSelection = section
    print(ArrayOfCollapsable!)
}

}

我先重新加载上一节，然后重新加载更改的部分
