How add cells in UITableView on button click? - ios

Question

I have a UITableView.It has two custom prototype cells.Now one cell is fixed it will be just remain one in tableview but another cell will be added to tableview again & again on button click.
below is code for the tableview methods:
func numberOfSections(in tableView: UITableView) -> Int {
return 2
}
func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
return arr_fields.count
}
func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
if indexPath.section == 0 {
let cellIndentifier="property"
let cell:CreatePropertyCell=tableView.dequeueReusableCell(withIdentifier: cellIndentifier, for: indexPath) as! CreatePropertyCell
cell.layer.borderWidth = 2.0
cell.layer.borderColor = UIColor.gray.cgColor
cell.txt_propertyName.attributedPlaceholder = NSAttributedString(string:"Name of property",
attributes:[NSForegroundColorAttributeName: UIColor.gray])
return cell
} else {
let cellIdentifier = "attribute"
let cell:AddProperty=tableView.dequeueReusableCell(withIdentifier: cellIdentifier, for: indexPath) as! AddProperty
cell.layer.borderWidth = 2.0
cell.layer.borderColor = UIColor.gray.cgColor
cell.txt_AddProperty.attributedPlaceholder = NSAttributedString(string:"Property Attribute",
attributes:[NSForegroundColorAttributeName: UIColor.gray])
cell.btnAdd.tag=indexPath.row
return cell
}
}
func tableView(_ tableView: UITableView, heightForHeaderInSection section: Int) -> CGFloat {
return 15
}
func tableView(_ tableView: UITableView, viewForHeaderInSection section: Int) -> UIView? {
let header = UIView()
header.backgroundColor = UIColor.clear
return header
}
#IBAction func actionAddProperty(_ sender: AnyObject) {
let cellIdentifier = "attribute"
let cell:AddProperty = self.tableView.dequeueReusableCell(withIdentifier: cellIdentifier) as! AddProperty
cell.layer.borderWidth = 2.0
cell.layer.borderColor = UIColor.gray.cgColor
cell.txt_AddProperty.attributedPlaceholder = NSAttributedString(string:"Property Attribute",
attributes:[NSForegroundColorAttributeName: UIColor.gray])
cell.tag=sender.tag!+1
arr_fields.append(cell)
tableView.reloadData()
print("tag is \(sender.tag!)")
}
Now i just want to add second cell to the table view not the both the cells.As of now it adds both the cells to the table view.

Try this:
func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
if section == 0 {
return 1
} else {
return arr_fields.count
}
}
Insert Cell: Rather than reloading Table, insert one cell into the Table:
#IBAction func actionAddProperty(_ sender: AnyObject) {
let cellIdentifier = "attribute"
let cell:AddProperty = self.tableView.dequeueReusableCell(withIdentifier: cellIdentifier) as! AddProperty
cell.layer.borderWidth = 2.0
cell.layer.borderColor = UIColor.gray.cgColor
cell.txt_AddProperty.attributedPlaceholder = NSAttributedString(string:"Property Attribute",
attributes:[NSForegroundColorAttributeName: UIColor.gray])
cell.tag=sender.tag!+1
let indexPath = NSIndexPath.init(forRow: arr_fields.count-1, inSection: 1)
tableView.beginUpdates()
arr_fields.append(objComment)
tableView.insertRowsAtIndexPaths([indexPath], withRowAnimation: .Automatic)
tableView.endUpdates()
}
