Insert row tableview with a button at last section - ios

Question

I want to make a tableview with a button in the section. I want the button to add one more row to a tableview like this
Here is the source code:
func numberOfSections(in tableView: UITableView) -> Int {
return 2
}
func tableView(_ tableView: UITableView, numberOfRowsInSection sectionInd: Int) -> Int {
if sectionInd == 0 {
return others.count
} else {
return 1
}
}
func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
if indexPath.section == 0 {
let cell = tableView.dequeueReusableCell(withIdentifier: "ShareCell", for: indexPath as IndexPath) as! SelectOthersTableViewCell
cell.firstName.text = others[indexPath.row].firstname
cell.lastName.text = others[indexPath.row].lastname
return cell
} else {
let cell = tableView.dequeueReusableCell(withIdentifier: "addCell", for: indexPath as IndexPath) as! addTableCell
cell.addCells.tag = indexPath.row
cell.addCells.addTarget(self, action: #selector(OthersViewController.addButtonClicked(sender:)), for: UIControlEvents.touchUpInside)
return cell
}
}
func tableView(_ tableView: UITableView, heightForRowAt indexPath: IndexPath) -> CGFloat {
var height:CGFloat = CGFloat()
if indexPath.section == 0 {
height = 145
} else {
height = 50
}
return height
}
#objc func addButtonClicked(sender:UIButton) {
data.append("Guest 1")
let buttonPosition = sender.convert(CGPoint.zero, to: self.tableView)
let indexPath = self.tableView.indexPathForRow(at: buttonPosition)
print("indexPath \(indexPath!)")
selectedIndexes[indexPath!] = !(selectedIndexes[indexPath!] ?? false)
tableView.reloadRows(at: [indexPath!], with: .automatic)
tableView.beginUpdates()
tableView.insertRows(at: [IndexPath(row: data.count-1, section: 0)], with: .automatic)
tableView.endUpdates()
}
i need help please. How to add new row by tap button on icon (+)?

Answer 1

On click of "Add" button, You should not reload the the entire table view because it increases the processing time. Instead of that you can use of
beginUpdates and endUpdates for inserting new cell when button clicked.
Basic Approaches:
(1). On click of "Add", update your data-source for table-view.
dataSource.append(NewRecord)
(2). Insert the new cell:
tableView.beginUpdates()
tableView.insertRows(at: [IndexPath(row: dataSource.count-1, section: 0)], with: .automatic)
tableView.endUpdates()
Reviewing your Code:
func addButtonClicked(sender:UIButton) {
data.append("Guest 1")
.....
}
Your datasource is others on which the tableview is created and configured.
But on click of add button (addButtonClicked function), you are not updating the others data-source. Please verify it, except that your code seems good.

Answer 2

fun onPlusButtonClicked(){
sections.append(whatever you want)
items[2].append(["1", "2", "3", "4"]) // whatever you want to add here
tableview.reloadData() // you can call this on a background thread as well, if its not working
}
// Ex of how to use with tableview
var sections = Your array
var items = your array
func tableView(_ tableView: UITableView, titleForHeaderInSection section: Int) -> String? {
return sections[section]
}
func numberOfSections(in tableView: UITableView) -> Int {
return sections.count
}
func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
return items[section].count
}
