如何在单个调用中填充多个集合

Question

我无法使用用户名填充评论。

 override func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
    let cell = tableView.dequeueReusableCell(withIdentifier: "HomeCell", for: indexPath) as! HomeTableViewCell
    cell.postsText.text = postLists[indexPath.row].postText
    i = indexPath.row
    return cell
}
func collectionView(_ collectionView: UICollectionView, numberOfItemsInSection section: Int) -> Int {
        return (postLists[i].imageUrlList?.count)!
}

func collectionView(_ collectionView: UICollectionView, cellForItemAt indexPath: IndexPath) -> UICollectionViewCell {
    let cell = collectionView.dequeueReusableCell(withReuseIdentifier: "ImageCell", for: indexPath) as! PhotosCollectionCell
        let url =  postLists[i].imageUrlList![indexPath.row]
            let imgUrl = URL(string: url)
            URLSession.shared.dataTask(with: imgUrl!, completionHandler: { (data, response, error) in
                if error != nil {
                    // if download hits an error, so lets return out
                    print(error)
                    return
                }
                // if there is no error happens...
                DispatchQueue.main.asyncAfter(deadline: .now() + 0.1) { // in half a second...
                    cell.postPhoto.image = UIImage(data: data!)
                }
            }).resume()
    return cell
}
