How to set manual scroll position when collection view loads in swift? - swift

Question

I have the main table view where collection view is settled in table view section header because of the horizontal scroll view. when I click on collection view (row 1) table view reloads. but when I click on collection view row 5, it reloads the table view and shows the collection scroll position from the beginning. Please help me out to set the manual scroll position for collection view which is inside table view.
Here is code what I am using.
func numberOfSections(in tableView: UITableView) -> Int
{
return 2
}
func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int
{
if section == 0
{
return 1
}
else
{
return 1
}
}
func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell
{
if indexPath.section == 0
{
let cell = tableView.dequeueReusableCell(withIdentifier: "banTableViewCell", for: indexPath) as! banTableViewCell
return cell
}
else
{
if chkVal == 0
{
let cell = tableView.dequeueReusableCell(withIdentifier: "onepageTableViewCell", for: indexPath) as! onepageTableViewCell
return cell
}
else if chkVal == 1
{
let cell = tableView.dequeueReusableCell(withIdentifier: "onepageTableViewCell", for: indexPath) as! onepageTableViewCell
return cell
}
else if chkVal == 2
{
let cell = tableView.dequeueReusableCell(withIdentifier: "onepageTableViewCell", for: indexPath) as! onepageTableViewCell
return cell
}
else if chkVal == 3
{
print("its cming gallery there")
let cell = tableView.dequeueReusableCell(withIdentifier: "containerTableViewCell", for: indexPath) as! containerTableViewCell
return cell
}
else
{
print("its cming calendar there")
let cell = tableView.dequeueReusableCell(withIdentifier: "galTableViewCell", for: indexPath) as! galTableViewCell
return cell
}
}
}
func tableView(_ tableView: UITableView, viewForHeaderInSection section: Int) -> UIView?
{
if section == 0
{
let view = UIView(frame: CGRect(x:0, y:0, width:0, height:0))
return view
}
else
{
let SegCell = tableView.dequeueReusableCell(withIdentifier: "segTableViewCell") as! segTableViewCell
SegCell.segcol.dataSource = self as UICollectionViewDataSource
SegCell.segcol.delegate = self as UICollectionViewDelegate
SegCell.segcol.isPagingEnabled = true
SegCell.segcol.isScrollEnabled = true
SegCell.segcol.showsHorizontalScrollIndicator = true
SegCell.segcol.register(UINib(nibName: "segCollectionViewCell", bundle: nil), forCellWithReuseIdentifier: "segCollectionViewCell")
// Initialization code
let indexPath = NSIndexPath(row: 3, section: 0)
SegCell.segcol.scrollToItem(at: indexPath as IndexPath, at: UICollectionViewScrollPosition.right, animated: false)
return SegCell
}
}
//Collection View Set
func collectionView(_ collectionView: UICollectionView, numberOfItemsInSection section: Int) -> Int
{
return 5
}
func collectionView(_ collectionView: UICollectionView, cellForItemAt indexPath: IndexPath) -> UICollectionViewCell
{
let cell = collectionView.dequeueReusableCell(withReuseIdentifier: "segCollectionViewCell", for: indexPath as IndexPath) as! segCollectionViewCell
if indexPath.row == 0
{
cell.TextSeg.text = "FITNESS REPORT CARD"
}
else if indexPath.row == 1
{
cell.TextSeg.text = "FITNESS STATS"
}
else if indexPath.row == 2
{
cell.TextSeg.text = "DIET & NUTRITION"
}
else if indexPath.row == 3
{
cell.TextSeg.text = "GALLERY"
}
else if indexPath.row == 4
{
cell.TextSeg.text = "CALENDAR"
}
return cell
}
func collectionView(_ collectionView: UICollectionView,layout collectionViewLayout: UICollectionViewLayout,
sizeForItemAt indexPath: IndexPath) -> CGSize
{
return CGSize(width:150, height:46)
}
func collectionView(_ collectionView: UICollectionView, didSelectItemAt indexPath: IndexPath)
{
if indexPath.row == 0
{
tbl.reloadData()
}
else if indexPath.row == 1
{
tbl.reloadData()
}
else if indexPath.row == 2
{
tbl.reloadData()
}
else if indexPath.row == 3
{
tbl.reloadData()
}
else if indexPath.row == 4
{
tbl.reloadData()
}
}
It's not setting the scroll position in the collection view.
Thanks
