Form

Usage

How to create a form

Instagram Example

To run the example project, clone the repo, and run pod install from the Example directory first.

Using this library, we can create the following layout. (I use Pastel and ActiveLabel for demo purposes.)

Instagram Example Code

import UIKit
import Form
import Pastel
import ActiveLabel


class InstagramSignInViewController: UIViewController {

    let label = ActiveLabel()
    
    override var preferredStatusBarStyle: UIStatusBarStyle {
        return .lightContent
    }
    
    override func viewDidLoad() {
        super.viewDidLoad()

        setNeedsStatusBarAppearanceUpdate()

        Form(in: self, constructor: { form in
            
            // Add the instagram pastel header.
            let instaView = InstagramView(frame: self.view.bounds)
            form.add(view: instaView)
            instaView.widthAnchor.constraint(equalTo: self.view.widthAnchor).isActive = true
            instaView.heightAnchor.constraint(equalToConstant: 145).isActive = true
            
            Input(form: form).placeholder("Phone number, username or email").style { input in
                input.textField.font = UIFont.systemFont(ofSize: 11)
            }.bind(.formOnSubmit, .nonempty, .shake).top(36).horizontal(36).height(43).bottom(0).style {
                $0.contentView.backgroundColor = UIColor.foreground
                $0.contentView.layer.cornerRadius = 4
                $0.contentView.layer.masksToBounds = true
                $0.contentView.layer.borderColor = UIColor.border.cgColor
                $0.contentView.layer.borderWidth = 1 / UIScreen.main.scale
            }

            Input(form: form).placeholder("Password").secure(true).style { input in
                input.textField.font = UIFont.systemFont(ofSize: 11)
            }.bind(.formOnSubmit, .nonempty, .shake).top(15).horizontal(36).height(43).bottom(20).style {
                $0.contentView.backgroundColor = UIColor.foreground
                $0.contentView.layer.cornerRadius = 4
                $0.contentView.layer.masksToBounds = true
                $0.contentView.layer.borderColor = UIColor.border.cgColor
                $0.contentView.layer.borderWidth = 1 / UIScreen.main.scale
            }
            
            Button(form: form).title("Login").style { button in
                button.button.backgroundColor = .blue
                button.button.layer.cornerRadius = 4
                button.button.layer.masksToBounds = true
                button.contentView.backgroundColor = .disabled
                button.button.titleLabel?.font = UIFont.boldSystemFont(ofSize: 12)
            }.bind(.formOnChange) { loginButton in
                print(form.isValid)
                loginButton.contentView.backgroundColor = form.isValid ? .enabled : .disabled
            }.height(44).horizontal(36).bottom(20)
            
            
            let signinLabel = LinkLabel(title: "Forgot your login details? Get help signing in.", pattern: "\\Q Get help signing in.\\E", handler: {
                print("Sign in.")
            })
            signinLabel.font = UIFont.boldSystemFont(ofSize: 10)
            form.add(view: signinLabel)
            
            Separator(form: form).title("OR").style {
                $0.label?.textColor = .gray
                $0.label?.font = UIFont.systemFont(ofSize: 11)
            }.horizontal(36).vertical(20)
            

            form.add(view: FacebookButton())

            
            let signupLabel = LinkLabel(title: "Don't have an account? Sign up.", pattern: "\\Q Sign up.\\E", handler: {
                print("Sign up")
            })
            signupLabel.font = UIFont.boldSystemFont(ofSize: 10)
            signupLabel.heightAnchor.constraint(equalToConstant: 80).isActive = true
            form.add(view: signupLabel)

        }).navigation(true)
    }
    
    override func touchesBegan(_ touches: Set<UITouch>, with event: UIEvent?) {
        super.touchesBegan(touches, with: event)
        self.view.endEditing(true)
    }
}
