Adding a UITableView to a UICollectionViewCell

I'm trying to embed a UITableView into a UICollectionViewCell. I'm managing to get everything to load. However, when it does load it up it seems to randomly use the last loaded value for the UITableView List Items. My DebugPrint Output seems to load all of the CollectionViewCells before even referencing the TableView. Once the CollectionViewCells are set, then it populates the TableView with whatever value it is left with. How can I resolve this so that I'm using the correct values? I suspect it is something to how I'm using IndexPath however I'm fairly new to Swift.

Populating UICollectionView



override func collectionView(_ collectionView: UICollectionView, cellForItemAt indexPath: IndexPath) -> UICollectionViewCell {
let cell = collectionView.dequeueReusableCell(withReuseIdentifier: releaseIdentifier, for: indexPath) as! ReleaseCollectionViewCell

let vid: VideoItem
vid = Video[indexPath.item]

let rating = vid.Rating
let denominator = 2.0
let roundedRating = round(rating*denominator )/denominator

if vid.SiteVideoID != 0 {
cell.ReleaseImage.setImageFromURl(stringImageUrl: "(file.BaseURL)/sitePictures/(GetFilePath(ID: String(vid.SiteVideoID)))/(String(vid.SiteVideoID)).jpg")
} else {
cell.ReleaseImage.setImageFromURl(stringImageUrl: "(file.BaseURL)/pictures/(GetFilePath(ID: String(vid.VideoID)))/(String(vid.VideoID))_001.png")
}

cell.ReleaseDate.text = vid.ReleaseDate
cell.ReleaseTitle.text = vid.Title

cell.SiteLogo.setImageFromURl(stringImageUrl: "(file.BaseURL)/siteLogos/" + String(vid.SiteID) + ".png")

if vid.VideoID == 0 {
cell.ReleaseImage.alpha = 0.5
} else {
cell.ReleaseImage.alpha = 1.0
}

indexPathItem = -1
indexPathItem = indexPath.item
debugPrint(indexPathItem)

cell.TagsView.delegate = self
cell.TagsView.dataSource = self
return cell
}


and for populating the TableView



extension MiscCollectionViewController: UITableViewDataSource {
func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
if indexPathItem != -1 {
return Video[indexPathItem].Tags.count
} else {
return 0
}
}
func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
let tags = tableView.dequeueReusableCell(withIdentifier: "Tag", for: indexPath) as! TagTableViewCell
debugPrint(String(indexPathItem) + " " + Video[indexPathItem].Tags[indexPath.row])
tags.TagLabel.text = String(indexPathItem) //Video[indexPathItem].Tags[indexPath.row]

  • How many collection view cells are there? Because if the number is fixed and less, I would recommend using a few views instead of a collection view.

  • @Damon It can be up to 500 depending on the result set from the database

  • Try tableview.reload() before the return cell statement of the Collection View's cellForItemAt method.

  • @Damon it won't build if I put it in the func collectionView or did you mean the tableview?

  • @Damon - update added cell.TagsView.reloadData() before the return cell and got the same result unfortunately. Interestingly though, the number of rows being returned seem to be correct. It is just the values of the rows that are wrong
