FUISwitchFormCell

The reusable UI component implemented as an UITableViewCell to allow user to choose a boolean value using a switch for a property.

FUISwitchFormCell

The developer should set the following properties on the cell, in their implementation of UITableViewDataSource cellForRow(at:) function:

  • keyName: The key name of the property
  • value: The value of the property, as Bool
  • isEditable: Indicates if the cell’s value may be modified. Defaults to true.

And, an onChangeHandler:

  • onChangeHandler: a handler closure, which is invoked on changes to the value

The following is an example of usage in an application UITableViewController:

Important

The app’s UITableViewController must subclass FUIFormTableViewController
override func viewDidLoad() {
    super.viewDidLoad()
    self.tableView.register(FUISwitchFormCell.self, forCellReuseIdentifier: FUISwitchFormCell.reuseIdentifier)
}

override func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
    let cell = tableView.dequeueReusableCell(withIdentifier: FUISwitchFormCell.reuseIdentifier, for: indexPath) as! FUISwitchFormCell
    cell.keyName = "Confirmed"
    cell.value = myObject.isConfirmed
    cell.onChangeHandler = { newValue in
        myObject.isConfirmed = newValue
    }

    return cell
}

Theming

Supported style classes and attributes.

fdlFUISwitchFormCell {
   // Table view cell related attributes.
   // ...
}

fdlFUISwitchFormCell_title {
   // Font attributes
   font { -style | -name | -size }
   font-color

   // Number of lines
   text-line-clamp

   // Text alignment
   text-align
}

fdlFUISwitchFormCell_switch {
   tint-color
   on-tint-color
}
  • The value type is Bool.

    Declaration

    Swift

    public typealias ValueType = Bool
  • The value of the property. Default to be false.

    Declaration

    Swift

    public var value: Bool { get set }
  • Implementation of change handler. Is invoked on changes to the value property.

    Declaration

    Swift

    public var onChangeHandler: ((Bool) -> Void)? { get set }
  • A boolean determines if the layout update of parent table view (hosting the switch form cell) should be animated when the value` property is changed.

    Declaration

    Swift

    public var isUpdatingTableView: Bool { get set }
  • Indicates if the value of the cell could be changed or not. The default is true.

    Declaration

    Swift

    public var isEditable: Bool { get set }
  • isEnabled and isEditable are in sync.

    Declaration

    Swift

    public override var isEnabled: Bool { get set }
  • The key name of the property.

    Declaration

    Swift

    @IBInspectable
    public var keyName: String? { get set }
  • The UISwitch in this cell.

    Declaration

    Swift

    public var switchView: UISwitch { get }
