无法在UItableviewcell中加载collectionview

Question

从自定义tablecell重新加载时，Collectionview重新加载不起作用。

我在一个collectionview单元格中放了一个下拉列表。这个下拉列表也无法正常工作。

以下是代码：

class HotelAvailableRoomsTVCell: UITableViewCell {

    @IBOutlet weak var collectionView: UICollectionView!

    //MARK: Life cycle
    override func awakeFromNib() {
        super.awakeFromNib()
        let nib = UINib.init(nibName: "AvailableRoomCVCell", bundle: nil)
        collectionView.register(nib, forCellWithReuseIdentifier: "AvailableRoomCVCell")
        collectionView.delegate = self
        collectionView.dataSource = self
        // Initialization code
    }

    func initCellWithData(roomJSON:JSON,indexPath:IndexPath,isSingle:Bool) {
        DispatchQueue.main.async {
            self.collectionView.reloadData()
        }

   }
}

在viewController中：

 func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell  {
     let cell = tableView.dequeueReusableCell(withIdentifier: "HotelAvailableRoomsTVCell", for: indexPath) as! HotelAvailableRoomsTVCell
     cell.delegate = self
     cell.initCellWithData(roomJSON: (json)!, indexPath: indexPath as IndexPath, isSingle: true)
    return cell;
}

屏幕是： 我使用了具有动态数量的单元格的tableview作为collectionview。此集合视图包含一个下拉列表，如图所示

首先，做到这一点＆amp;检查

Selection

你也可以这样做，（已由我及其工作完成），

通过在Option Explicit Private Sub OptionButton1_Click() Dim sht As Worksheet Set sht = ThisWorkbook.ActiveSheet ' instead I recommend to reference a worksheet ' by name: ThisWorkbook.Worksheets("SheetName") Dim Shape1 As Shape Set Shape1 = sht.Shapes.AddShape(msoShapeRectangle, 285, 74.25, 112.5, 108.75) Shape1.OLEFormat.Object.ShapeRange.Line.Visible = msoFalse With Shape1.OLEFormat.Object.ShapeRange.Fill .Visible = msoTrue .ForeColor.ObjectThemeColor = msoThemeColorAccent6 .ForeColor.TintAndShade = 0 .ForeColor.Brightness = 0.6000000238 .Transparency = 0 .Solid End With Dim Shape2 As Shape Set Shape2 = sht.Shapes.AddShape(msoShapeRectangle, 285.75, 74.25, 111.75, 21.75) Shape2.OLEFormat.Object.ShapeRange.Line.Visible = msoFalse With Shape2.OLEFormat.Object.ShapeRange.Fill .Visible = msoTrue .ForeColor.ObjectThemeColor = msoThemeColorAccent6 .ForeColor.TintAndShade = 0 .ForeColor.Brightness = 0.400000006 .Transparency = 0 .Solid End With sht.Shapes.Range(Array(Shape1.Name, Shape2.Name)).Group End Sub 中创建var来传递数据。

class HotelAvailableRoomsTVCell: UITableViewCell, UICollectionViewDelegate,UICollectionViewDataSource

在HotelAvailableRoomsTVCell

var collectionData : [String : Any] = []
