Navigate through textfields in UITableView swift

Question

Trying to navigate through text fields in UITableView . Able to navigate through text fields on simple view but not getting how to navigate when text fields are in UITableView .

Below is the code tried so far:

func textFieldDidBeginEditing(textField: UITextField)
{

    //textField.inputAccessoryView = numberToolbar
    if(textField == txtConfirmPassword)
    {
        textField.returnKeyType = UIReturnKeyType.Done
    }
    else
    {
        textField.returnKeyType = UIReturnKeyType.Next
    }
}

Please guide thanks.

Update:

func textFieldDidBeginEditing(textField: UITextField)
{
    if(delegate != nil)
    {
        delegate?.performSelector(NSSelectorFromString("editingTextField"))
    }

    if(textField.tag == 3)
    {
        textField.returnKeyType = UIReturnKeyType.Done
    }
    else
    {
        textField.returnKeyType = UIReturnKeyType.Next
    }
}

func textFieldShouldReturn(textField: UITextField) -> Bool
{
    if(delegate != nil)
    {
        delegate?.performSelector(NSSelectorFromString("editingDone"))
    }
    if(textField.tag == 3)
    {
        textField.resignFirstResponder()
        delegate?.performSelector(NSSelectorFromString("editingDone"))

    }

     let nextTage=textField.tag+1
    // Try to find next responder
    let nextResponder=textField.superview?.viewWithTag(nextTage) as UIResponder!

    if (nextResponder != nil){
        // Found next responder, so set it.
        nextResponder?.becomeFirstResponder()
    }
    else
    {
        // Not found, so remove keyboard
        textField.resignFirstResponder()
    }
    return true
}

Here is the code for Swift 2.1

Here I have taken SampleTableViewCell which is a custom cell in which i have created textField.

For the purpose I have just taken the tag based on cell, so while accessing it in the textField's delegate method, You can know the textField is for which cell.

Here is the code :

//UITableView Delegate

func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell
{
     let cell = tableView.dequeueReusableCellWithIdentifier("cell", forIndexPath: indexPath) as! SampleTableViewCell
    cell.txtFld.delegate = self;
    cell.txtFld.tag = indexPath.row + 100

    cell.selectionStyle = UITableViewCellSelectionStyle.Gray;


    return cell;
}

UPDATE : Here is the delegate for TextField

//UITextField Delegate

func textFieldDidBeginEditing(textField: UITextField)
{

    //textField.inputAccessoryView = numberToolbar
    if(textField.tag == 100)
    {
        textField.returnKeyType = UIReturnKeyType.Done
    }
    else
    {
        textField.returnKeyType = UIReturnKeyType.Next
    }
}

Here I have navigate to next textfield by clicking the return button of text field.

// called when 'return' key pressed. return NO to ignore.
func textFieldShouldReturn(textField: UITextField) -> Bool
{
    textField.resignFirstResponder();

    if(textField.tag == 100)
    {
        let txtFld = self.tblList.viewWithTag(101);
        txtFld?.becomeFirstResponder();
    }

    return true;
}

Hope it helps.

Happy coding ...

You should use the tag to check if the current textfield is the first responder.

Note: Swift 3.

    func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
        // let's say that you are reading the date from an array...
        return myArray.count
    }

    func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
        let cell = tableView.dequeueReusableCell(withIdentifier: "Cell") as! TableViewCell

        // here you set the tag
        cell.myTextfield?.tag = indexPath.row

        // ...

        return cell
    }


    func textFieldDidBeginEditing(textField: UITextField) {
        // now, based on textField you can check (tag == myArray.count - 1 means it is the last)
        textField.returnKeyType = (textField.tag == myArray.count - 1) ? .done : .next
    }

Hope that helped.

Best way for me.

UITableViewCell

class CustomTableViewCell: UITableViewCell {
     var nextTextField: (() -> Void)?
}

UITableViewDataSource, UITableViewDelegate

func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
    ...
    cell.nextTextField = { in
        guard let cell = tableView.cellForRow(at: IndexPath(row: indexPath.row + 1, section: 0)) as? CustomTableViewCell else {
            return
        }
        cell.textField.becomeFirstResponder()
    }
    return cell
}

UITextFieldDelegate

...
func textFieldDidBeginEditing(textfield: RCTextField) {
    if viewModel.items.count-1 == textfield.tag {
       textField.returnKeyType = UIReturnKeyType.done
    } else {
       textField.returnKeyType = UIReturnKeyType.next
    }
}
...
