How to make first text input become first responder and show keyboard with Eureka forms?

Question

I am using the Eureka forms swift library here: Eureka forms

I would like to have my first row of the input form become the first responder every time the view appears. I tried adding a .cellUpdate callback which is fired everytime the view appears, and doing a cell.becomeFirstResponder() but this did not work. Could someone with experience in this library please help? Thanks.

what is the type of your cell? is a TextRow, ImageRow, etc? – Reinier Melian Jul 29 '16 at 14:14 — Reinier Melian, Jul 29 '16 at 14:14

Try this

import UIKit
import Eureka

class ViewController3: FormViewController {

    override func viewDidLoad() {
        super.viewDidLoad()
        form +++ Section("Custom cells")
            <<< TextRow("TextRow"){_ in
        }
    }

    override func viewWillAppear(animated: Bool) {
        super.viewWillAppear(animated)
        let row = self.form.rowByTag("TextRow") as! TextRow
        row.cell.textField.becomeFirstResponder()
    }
}

I hope this helps you

Thank you Reinier!!! I see that you are a contributor to Eureka. Would greatly appreciate if you could take a look at my other question: http://stackoverflow.com/questions/38662315/how-do-you-remove-the-next-previous-done-toolbar-in-eureka-forms – demig0d Jul 29 '16 at 15:22
@demig0d I will see, and post my results, don't worry – Reinier Melian Jul 29 '16 at 15:24
Thank you so much! – demig0d Jul 29 '16 at 15:24
This doesn't seem to work on iOS 10 or with the newer Eureka. What does work is calling this in `viewDidAppear` instead of `viewWillAppear` – Peterdk Apr 24 '17 at 15:34
what if we have a PickerInputRow, which we want to make it as the firstResponder? – Alex Andrews Feb 13 '18 at 12:55
I will review that @Alexi as soon as I have something I will post it as update – Reinier Melian Feb 13 '18 at 12:56
hey @ReinierMelian, got the solution. The cell has a member named cellBecomeFirstResponder() – Alex Andrews Feb 13 '18 at 13:18
Nice man you got it, congratulations! I was lunching ;) best regards @Alexi – Reinier Melian Feb 13 '18 at 13:31

Hook it in cellSetup, this way we don't need to lookup the cell in viewDidAppear

form +++ Section("")
        <<< TextRow() {
            $0.title = "Name"
            $0.value = list?.name ?? ""
            $0.cellSetup() { cell, row in
                  cell.textField.becomeFirstResponder()
            }
            $0.onChange() {
                self.list.name = $0.value ?? ""
            }
        }

Inspired by Reinier's answer, here is another way worked for me.

Directly call $0.cell.textField.becomeFirstResponder() in setting up the form.

        form +++ Section()
        <<< ZipCodeRow() {
            $0.value = postal_code
            $0.cell.textField.becomeFirstResponder()
            }

Swift 4:

In ViewDidLoad() add:

let row = self.form.rowBy(tag: "TextRow.tag") as! TextRow
row.cell.textField.becomeFirstResponder()
