Swift Discrepancy of UICollectionView inside UITableViewCell - ios

Question

import UIKit

#IBOutlet weak var imageV: UIImageView!
let collectionArray = generateRandomData()
var index = 0
override func awakeFromNib()

super.awakeFromNib()
// Initialization code
}
override func setSelected(_ selected: Bool, animated: Bool)
{
super.setSelected(selected, animated: animated)
// Configure the view for the selected state
}
func getCellSize(_ targetSize: CGSize) -> CGSize
{
return CGSize(width: 44, height: 44)
}
override func prepareForReuse()
{
self.collectionView.contentOffset = .zero
}
override func systemLayoutSizeFitting(_ targetSize: CGSize) -> CGSize
{
// let frame = self.collectionView.frame
// self.collectionView.layoutIfNeeded()
//
// let height: CGFloat = self.collectionView.collectionViewLayout.collectionViewContentSize.height
// self.collectionViewHeight.constant = height
// self.collectionView.frame = CGRect(x: frame.minX, y: frame.minY, width: frame.width, height: height)
// return self.collectionView.collectionViewLayout.collectionViewContentSize
self.collectionViewHeight.constant = collectionView.collectionViewLayout.collectionViewContentSize.height
return self.contentView.systemLayoutSizeFitting(UIView.layoutFittingCompressedSize)
}
override func systemLayoutSizeFitting(_ targetSize: CGSize, withHorizontalFittingPriority horizontalFittingPriority: UILayoutPriority, verticalFittingPriority: UILayoutPriority) -> CGSize
{
self.collectionView.layoutIfNeeded()
self.collectionViewHeight.constant = collectionView.collectionViewLayout.collectionViewContentSize.height
return self.contentView.systemLayoutSizeFitting(UIView.layoutFittingCompressedSize)
}
}

import UIKit
class My_CustomViewController: UIViewController
{
#IBOutlet weak var tableView: UITableView!
override func viewDidLoad() {
super.viewDidLoad()
// Enable automatic row auto layout calculations
self.tableView.rowHeight = UITableView.automaticDimension
// Set the estimatedRowHeight to a non-0 value to enable auto layout.
self.tableView.estimatedRowHeight = 44
}
/*
// MARK: - Navigation
// In a storyboard-based application, you will often want to do a little preparation before navigation
override func prepare(for segue: UIStoryboardSegue, sender: Any?) {
// Get the new view controller using segue.destination.
// Pass the selected object to the new view controller.
}
*/
}
extension My_CustomViewController: UITableViewDelegate, UITableViewDataSource
{
func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int
{
return 66
}
func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell
{
let cell = tableView.dequeueReusableCell(withIdentifier: "TbVCell", for: indexPath) as! My_CustomTableViewCell
cell.collectionView.tag = indexPath.row
cell.nameLabel.text = "\(indexPath.row)"
cell.numberLabel.text = "\(indexPath.row)"
cell.index = indexPath.row
print("cellForRowAt-----------\(indexPath.row)")
return cell
}
}
storyboard settings
here I am not able to get the required number of collection cells as expected by the numberOfItemsInSection function which is increasing with the tableviewcell number like 64 collectionview items for 64rth tableviewcell.
What I need to do to get exact matching of number of items with tableviewcell.
with none of the above variables I am able to keep track of the count to match.
