Adding UITextfield as cell's accessory view - uitableview

Question

I have 4 sections in my tableView, each section has single cell. When user selects the fourth section's cell, I want them to type on it. So I just added textfield as a accessoryView for that cell in didSelectRow function as shown below.
func tableView(tableView: UITableView, didSelectRowAtIndexPath indexPath: NSIndexPath) {
if indexPath.section == 3 {
//adding textField
theTextField = UITextField(frame: CGRectMake(10, 480, 300, 40))
theTextField.backgroundColor = UIColor.brownColor()
theTextField.placeholder = "Please type here...."
theTextField.textColor = UIColor.yellowColor()
theTextField.layer.cornerRadius = 10.0
selectedCell?.accessoryView = theTextField
}
But when I click on it, the keyboard is hiding that cell. I want the table view to scroll up. Please help me to resolve this or please please let me know if there is any other way to achieve this!

Answer 1

Not clear why you are implementing the cell specifications in "didSelectRowAtIndexPath" when a more logical place is in "cellForRowAtIndexPath". I implemented your code except putting the cell spec for section 3 in cellForRowAtIndexPath and the table cells are scrolled up as expected. See code below. To take advantage of the tableview scrolling the cell needs to be defined in cellRowForIndex. To meet your objective stated in the comment you can use the .hidden feature and insert the code as shown.
import UIKit
class: UITableViewController {
override func viewDidLoad() {
super.viewDidLoad()
}
override func didReceiveMemoryWarning() {
super.didReceiveMemoryWarning()
}
override func tableView(tableView: UITableView, didSelectRowAtIndexPath indexPath: NSIndexPath) {
if indexPath.section == 3 {
selectedCell.accessoryView?.backgroundColor = UIColor.brownColor()
selectedCell.accessoryView?.hidden = false
} else {
selectedCell.accessoryView?.hidden = true
}
}
override func numberOfSectionsInTableView(tableView: UITableView) -> Int {
return 4
}
override func tableView(tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
return 1
}
override func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell {
let cell = tableView.dequeueReusableCellWithIdentifier("cell", forIndexPath: indexPath) as UITableViewCell
if indexPath.section == 3 {
//adding textField
var theTextField = UITextField(frame: CGRectMake(10, 480, 300, 40))
theTextField.backgroundColor = UIColor.brownColor()
theTextField.placeholder = "Please type here...."
theTextField.textColor = UIColor.yellowColor()
theTextField.layer.cornerRadius = 10.0
cell.accessoryView = theTextField
cell.accessoryView?.hidden = true
}
else {
cell.textLabel!.text = "\(indexPath.section)"
}
return cell
}
}
