You can set the cell's appearance and events-callback at the same time.
ViewController and Cell do not need to override the provided defaults.

Simple Example

import Former

final class ViewController: FormViewController {

    override func viewDidLoad() {
        let labelRow = LabelRowFormer<FormLabelCell>()
            .configure { row in
                row.text = "Label Cell"
            }.onSelected { row in
                // Do Something
        let inlinePickerRow = InlinePickerRowFormer<FormInlinePickerCell, Int>() {
            $0.titleLabel.text = "Inline Picker Cell"
            }.configure { row in
                row.pickerItems = (1...5).map {
                    InlinePickerItem(title: "Option\($0)", value: Int($0))
            }.onValueChanged { item in
                // Do Something
        let header = LabelViewFormer<FormLabelHeaderView>() { view in
            view.titleLabel.text = "Label Header"
        let section = SectionFormer(rowFormer: labelRow, inlinePickerRow)
            .set(headerViewFormer: header)
        former.append(sectionFormer: section)


RowFormer is the base class of the class that manages the cell. A cell that is managed by the RowFormer class should conform to the corresponding protocol. Each of the RowFormer classes exposes event handling in functions named "on*" (e.g., onSelected, onValueChanged, etc...)
Default provided RowFormer classes and the protocols that corresponding to it are listed below.

example with LabelRowFormer

let labelRow = LabelRowFormer<YourLabelCell>(instantiateType: .Nib(nibName: "YourLabelCell")) {
    $0.titleLabel.textColor = .blackColor()
    }.configure { row in
        row.rowHeight = 44
        row.text = "Label Cell"
    }.onSelected { row in
        print("\(row.text) Selected !!")

update the cell

row.update { row in
    row.text = "Updated title"
row.cellUpdate { cell in
    cell.titleLabel.textColor = .redColor()

get cell instance

let cell = row.cell

set dynamic row height

row.dynamicRowHeight { tableView, indexPath -> CGFloat in
    return 100


ViewFormer is base class of the class that manages the HeaderFooterView.
A HeaderFooterView that is managed by the ViewFormer class should conform to the corresponding protocol. Default provided ViewFormer classes and the protocols that correspond to it are listed below.

Demo Class Protocol Default provided cell

Free CustomViewFormer None None LabelViewFormer LabelFormableView FormLabelHeaderView

example with LabelViewFormer

let headerView = LabelViewFormer<YourLabelView>(instantiateType: .Nib(nibName: "YourLabelView")) {
    $0.titleLabel.textColor = .blackColor()
    }.configure { view in
        view.viewHeight = 30
        view.text = "Label HeaderFooter View"


SectionFormer is a class that represents the Section of TableView.
SectionFormer can append, add, insert, remove the RowFormer and set the ViewFormer.

let section = SectionFormer(rowFormer: row1, row2, row3)
    .set(headerViewFormer: headerView)
    .set(footerViewFormer: footerView)

add the cell

section.append(rowFormer: row1, row2, row3)
section.add(rowFormers: rows)
section.insert(rowFormer: row, toIndex: 3)
section.insert(rowFormer: row, below: otherRow)
// etc...

remove the cell

section.remove(rowFormer: row)
// etc...

set the HeaderFooterViewe

section.set(headerViewFormer: headerView)
section.set(footerViewFormer: footerView)


Former is a class that manages the entire form.
Examples is below.
add the section or cell

former.append(sectionFormer: row)
former.add(sectionFormers: rows)
former.insert(sectionFormer: section, toSection: 0)
former.insert(rowFormer: row, toIndexPath: indexPath)
former.insert(sectionFormer: section, above: otherSection)
former.insert(rowFormers: row, below: otherRow)
// etc...

// with animation
former.insertUpdate(sectionFormer: section, toSection: 0, rowAnimation: .Automatic)
former.insertUpdate(rowFormer: row, toIndexPath: indexPath, rowAnimation: .Left)
former.insertUpdate(sectionFormer: section, below: otherSection, rowAnimation: .Fade)
former.insertUpdate(rowFormers: rows, above: otherRow, rowAnimation: .Bottom)
// etc...

remove the section or cell

former.remove(rowFormer: row1, row2)
former.remove(sectionFormer: section1, section2)
// etc...

// with animation
former.removeUpdate(sectionFormers: sections, rowAnimation: .Middle)
// etc...

Select and deselect the cell

former.select(indexPath: indexPath, animated: true, scrollPosition: .Middle)
former.select(rowFormer: row, animated: true)
// etc...

end editing


become editing next/previous cell

if former.canBecomeEditingNext() {
if former.canBecomeEditingPrevious() {

functions to setting event handling

public func onScroll(handler: ((scrollView: UIScrollView) -> Void)) -> Self    
public func onBeginDragging(handler: (UIScrollView -> Void)) -> Self
public func willDeselectCell(handler: (NSIndexPath -> NSIndexPath?)) -> Self
public func willDisplayCell(handler: (NSIndexPath -> Void)) -> Self

There is no need to inherit from the FormViewController class.
Instead, create an instance of UITableView and Former, as in the following example.

final class YourViewController: UIViewController {    

    private let tableView: UITableView = UITableView(frame: CGRect.zero, style: .Grouped) // It may be IBOutlet. Not forget to addSubview.
    private lazy var former: Former = Former(tableView: self.tableView)


Cell There is likewise no need to inherit from the default provided cell class (FormLabelCell etc ...); only conform to the corresponding protocol. You can use Nibs, of course. An example with LabelRowFormer:

final class YourCell: UITableViewCell, LabelFormableRow {

    // MARK: LabelFormableRow

    func formTextLabel() -> UILabel? {
        return titleLabel

    func formSubTextLabel() -> UILabel? {
        return subTitleLabel

    func updateWithRowFormer(rowFormer: RowFormer) {
        // Do something

    // MARK: UITableViewCell

    var titleLabel: UILabel?
    var subTitleLabel: UILabel?


RowFormer If you want to create a custom RowFormer, make your class inherit from BaseRowFormer and comply with the Formable protocol.
It must conform to ConfigurableInlineForm. In the case of InlineRowFomer, conform to the UpdatableSelectorForm case of SelectorRowFormer. Please look at the source code for details.
Examples of RowFormer using cells with two UITextFields:

public protocol DoubleTextFieldFormableRow: FormableRow {

    func formTextField1() -> UITextField
    func formTextField2() -> UITextField

public final class DoubleTextFieldRowFormer<T: UITableViewCell where T: DoubleTextFieldFormableRow>
: BaseRowFormer<T>, Formable {

    // MARK: Public

    override public var canBecomeEditing: Bool {
        return enabled

    public var text1: String?
    public var text2: String?

    public required init(instantiateType: Former.InstantiateType = .Class, cellSetup: (T -> Void)? = nil) {
        super.init(instantiateType: instantiateType, cellSetup: cellSetup)

    public final func onText1Changed(handler: (String -> Void)) -> Self {
        onText1Changed = handler
        return self

    public final func onText2Changed(handler: (String -> Void)) -> Self {
        onText2Changed = handler
        return self

    open override func cellInitialized(cell: T) {
        cell.formTextField1().addTarget(self, action: "text1Changed:", forControlEvents: .EditingChanged)
        cell.formTextField2().addTarget(self, action: "text2Changed:", forControlEvents: .EditingChanged)

    open override func update() {

        cell.selectionStyle = .None
        let textField1 = cell.formTextField1()
        let textField2 = cell.formTextField2()
        textField1.text = text1
        textField2.text = text2        

    // MARK: Private

    private final var onText1Changed: (String -> Void)?
    private final var onText2Changed: (String -> Void)?    

    private dynamic func text1Changed(textField: UITextField) {
        if enabled {
            let text = textField.text ?? ""
            self.text1 = text

    private dynamic func text2Changed(textField: UITextField) {
        if enabled {
            let text = textField.text ?? ""
            self.text2 = text
