ios - UITableView set tableview row hidden

Question

I have a custom tableview cell in grouptableview. And I have one hidden. I then have to make it visible. Cell tag is 3.

This is not working my code:

if (self.tableView.tag == 3) {
                self.tableView.hidden = NO; //Not working.
            }

Just i need make a one row is visible. I hope you understand.

In SWIFT you need to do two things,

1. HIDE your cell. (because reusable cell may conflict)

2. Set Height of cell to ZERO.

Look at here,

1. HIDE you cell.

   func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
       let myCell:UITableViewCell = tableView.dequeueReusableCell(withIdentifier: "cellID",for: indexPath) as! UITableViewCell
   
       if(indexPath.row < 2){
           myCell.isHidden = true
       }else{
           myCell.isHidden = false
       }
   
       return myCell
   }
   

2. Set Height of cell to ZERO.

   func tableView(_ tableView: UITableView, heightForRowAt indexPath: IndexPath) -> CGFloat {
       var rowHeight:CGFloat = 0.0
   
       if(indexPath.row < 2){
           rowHeight = 0.0
       }else{
           rowHeight = 55.0    //or whatever you like
       }
   
       return rowHeight
   } 
   

Using this you can remove reusable cell conflict issues.

You can do the same for cell?.tag also to hide specific cell by tag.
