QuickTableViewController

A simple way to create a table view for settings, including:

• Table view cells with UISwitch
• Table view cells with center aligned text for tap actions
• A section that provides mutually exclusive options
• Actions performed when the row reacts to the user interaction
• Easy to specify table view cell image, cell style and accessory type

Usage

Set up tableContents in viewDidLoad:

import QuickTableViewController

final class ViewController: QuickTableViewController {

  override func viewDidLoad() {
    super.viewDidLoad()

    tableContents = [
      Section(title: "Switch", rows: [
        SwitchRow(text: "Setting 1", switchValue: true, action: { _ in }),
        SwitchRow(text: "Setting 2", switchValue: false, action: { _ in })
      ]),

      Section(title: "Tap Action", rows: [
        TapActionRow(text: "Tap action", action: { [weak self] in self?.showAlert($0) })
      ]),

      Section(title: "Navigation", rows: [
        NavigationRow(text: "CellStyle.default", detailText: .none, icon: .named("gear")),
        NavigationRow(text: "CellStyle", detailText: .subtitle(".subtitle"), icon: .named("globe")),
        NavigationRow(text: "CellStyle", detailText: .value1(".value1"), icon: .named("time"), action: { _ in }),
        NavigationRow(text: "CellStyle", detailText: .value2(".value2"))
      ], footer: "UITableViewCellStyle.Value2 hides the image view."),

      RadioSection(title: "Radio Buttons", options: [
        OptionRow(text: "Option 1", isSelected: true, action: didToggleSelection()),
        OptionRow(text: "Option 2", isSelected: false, action: didToggleSelection()),
        OptionRow(text: "Option 3", isSelected: false, action: didToggleSelection())
      ], footer: "See RadioSection for more details.")
    ]
  }

  // MARK: - Actions

  private func showAlert(_ sender: Row) {
    // ...
  }

  private func didToggleSelection() -> (Row) -> Void {
    return { [weak self] row in
      // ...
    }
  }

}

NavigationRow

Detail Text Styles

NavigationRow(text: "UITableViewCellStyle.default", detailText: .none)
NavigationRow(text: "UITableViewCellStyle", detailText: .subtitle(".subtitle")
NavigationRow(text: "UITableViewCellStyle", detailText: .value1(".value1")
NavigationRow(text: "UITableViewCellStyle", detailText: .value2(".value2"))

Subtitle and the initializers with title/subtitle are deprecated and will be removed in v2.0.0.

Accessory Type

• The NavigationRow shows with different accessory types based on the action and accessoryButtonAction closures:

var accessoryType: UITableViewCell.AccessoryType {
  switch (action, accessoryButtonAction) {
  case (nil, nil):      return .none
  case (.some, nil):    return .disclosureIndicator
  case (nil, .some):    return .detailButton
  case (.some, .some):  return .detailDisclosureButton
  }
}

• The action will be invoked when the table view cell is selected.
• The accessoryButtonAction will be invoked when the accessory button is selected.

Images

enum Icon {
  case named(String)
  case image(UIImage)
  case images(normal: UIImage, highlighted: UIImage)
}

• Images in table view cells can be set by specifying the icon of each row.
• Table view cells in UITableViewCellStyle.value2 will not show the image view.

SwitchRow

• A SwitchRow is representing a table view cell with a UISwitch as its accessoryView.
• The action will be invoked when the switch value changes.

TapActionRow

• A TapActionRow is representing a button-like table view cell.
• The action will be invoked when the table view cell is selected.
• The icon, detail text, and accessory type are disabled in TapActionRow.

OptionRow

• An OptionRow is representing a table view cell with .checkmark.
• The action will be invoked when the selected state is toggled.

let didToggleSelection: (Row) -> Void = { [weak self] in
  if let option = $0 as? OptionRowCompatible, option.isSelected {
    // to exclude the event where the option is toggled off
  }
}

RadioSection

• RadioSection allows only one selected option at a time.
• Setting alwaysSelectsOneOption to true will keep one of the options selected.
• OptionRow can also be used with Section for multiple selections.

Customization

Rows

All rows must conform to Row and RowStyle. Additional interface to work with specific types of rows are represented as different protocols:

• NavigationRowCompatible
• OptionRowCompatible
• SwitchRowCompatible
• TapActionRowCompatible

Cell Classes

A customized table view cell type can be specified to rows during initialization.

// Default is UITableViewCell.
NavigationRow<CustomCell>(text: "Navigation", detailText: .none)

// Default is SwitchCell.
SwitchRow<CustomSwitchCell>(text: "Switch", switchValue: true, action: { _ in })

// Default is TapActionCell.
TapActionRow<CustomTapActionCell>(text: "Tap", action: { _ in })

// Default is UITableViewCell.
OptionRow<CustomOptionCell>(text: "Option", isSelected: true, action: { _ in })

Since the rows carry different cell types, they can be matched using either the concrete types or the related protocol:

let action: (Row) -> Void = {
  switch $0 {
  case let option as OptionRow<CustomOptionCell>:
    // only matches the option rows with a specific cell type
  case let option as OptionRowCompatible:
    // matches all option rows
  default:
    break
  }
}

Overwrite Default Configuration

You can use register(_:forCellReuseIdentifier:) to specify custom cell types for the table view to use. See CustomizationViewController for the cell reuse identifiers of different rows.

Table view cell classes that conform to Configurable can take the customization during tableView(_:cellForRowAt:):

protocol Configurable {
  func configure(with row: Row & RowStyle)
}

Additional setups can also be added to each row using the customize closure:

protocol RowStyle {
  var customize: ((UITableViewCell, Row & RowStyle) -> Void)? { get }
}

The customize closure overwrites the Configurable setup.

UIAppearance

As discussed in issue #12, UIAppearance customization works when the cell is dequeued from the storyboard. One way to work around this is to register nib objects to the table view. Check out AppearanceViewController for the setup.

tvOS Differences

• UISwitch is replaced by a checkmark in SwitchCell.
• TapActionCell does not use center aligned text.
• NavigationRow.accessoryButtonAction is not available.
• Cell image view's left margin is 0.

Limitation

When to use QuickTableViewController?

QuickTableViewController is good for presenting static table contents, where the sections and rows don't change dynamically after viewDidLoad.

It's possible to update the table contents by replacing a specific section or row. Using different styles on each row requires additional configuration as described in the Customization section.

When not to use it?

QuickTableViewController is not designed for inserting and deleting rows. It doesn't handle table view reload animation either. If your table view needs to update dynamically, you might want to consider other solutions such as IGListKit.
