UITableView内的CollectionView单元重复

Question

I have one table view in which every cell contains one collection view!

1) display only two cell in collectionview as my issue is when we scroll the tableview, collectoinview cell content is repeated in many other cell of tableview

myCode:

let tags = Tblarr[indexPath.row]["hashtags"] as! [String]
    if tags.count != 0
    {
        for var i in 0 ... tags.count - 1
        {
            if i < 2
            {
                cell.tagsView.addTag(tags[i])
                cell.collectionView.isHidden =   false
            }
        }
        if tags.count > 2
        {
            cell.lblCount.isHidden = false
            cell.lblCount.text = "+\(tags.count - 2)"
        }
        else
        {
            cell.lblCount.isHidden = true
        }
    }
    else{
        cell.lblCount.isHidden = true
        cell.collectionView.isHidden =   true
    }
    cell.fillCollectionView(with: cell.tagsView.tags)
    cell.widthConstraint.constant = cell.collectionView.contentSize.width

here I get only fixed width of collectionview without setting width according to content size & collectionview cells are repeated in other cell of tableview, even if cell is one , it will show 2 cell(when scrolled)

when load for the first time

when tableview is scrolled

//for storing array in collectionview from tableview

func fillCollectionView(with array: [String]) {
    self.collectionArr = array
    self.collectionView.reloadData()
}

Answer 1

I don't know what fillCollectionView does but it looks like you didn't consider that the table view cells are reused. So every time you call fillCollectionView you have to reset the content of your cell or the content or your collection view.

Answer 2

reload collectionView inside tableview

func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell { cell.fillCollectionView.reloadData() }

func fillCollectionView(with array: [String]) {
self.collectionArr.removeAll
self.collectionArr = array
self.collectionView.reloadData()

}
