Build a Sign In Form

Building a Sign In form with iForm is relatively easy:

import UIKit
import iForm

class SignInViewController: UIViewController, UITextFieldDelegate {

    private var form: iForm = iForm()
    override func viewDidLoad() {
        super.viewDidLoad()
        var formular: SignInForm = SignInForm()
        
        //Initialize sign-in form
        formular = form.initSignInForm(
                        //Submit button callback
            actionToPerform : UIAction() { _ in
                                //Retrieving the values in our text fields
                let textFieldsValues = self.form.getTextFieldsValues(from: self.form.getAllTextFields(from: formular))
                //Storing the data
                let email = textFieldsValues["Email"]
                let password = textFieldsValues["Password"]

                let detailsVC = DetailsViewController()
                detailsVC.email = email
                detailsVC.password = password
                //Passing the data to the next  View Controller
                self.navigationController?.pushViewController(detailsVC, animated: true)
            })
                //Add the form to the defined view
        form.display(formular, on: self.view, withConstraints: Constraints(horizontal: 0, vertical: -250, width: 0, height: 50))

                }
}

1. We first Initialized our iForm and SignInForm
2. Create the form with the initSignInForm() method of your object
3. Pass as an argument the action you want your submit button to do as the actionToPerform argument
   1. In that callback we get the values of our generated text fields through the iForm method getTextFieldsValues()
   2. Then we store them in variables
   3. And finally we simply pass them to our DetailViewController
4. Use the display() method to add the form the defined view with the defined constraints

Notes: The getTextFieldsValues() receives a UITextField table as an arguments, table that can be returned with the getAllTextFields() method
