FUISegmentedControlFormCell

@IBDesignable
open class FUISegmentedControlFormCell : FUIInlineValidationTableViewCell, FUIPropertyFormCell

A UITableViewCell subclass, which allows a user to view or select from a list of strings, using a Fiori-styled segmented control.

FUISegmentedControlFormCell

The value property of the cell is equal to the selectedSegmentIndex in the segmented control.

Specifying the height for segments by setting segmentHeight api. By default it is set to nil which means segment will adjust its height to fit content.

Color setting:

Setting text color of buttons in the cell for a state using setTintColor(_:for:) api. Currently disabled, normal and selected are supported.

cell.setTintColor(UIColor.red, for: .selected)

Code usage:

// Optionally, create an array of value option to localized string mappings
let buttonTitles: [[String: String]] = [["LO": "Low"], ["MED": "Medium"], ["HI": "High"]]

// Register FUISegmentedControlFormCell in viewDidLoad() method in the controller.
override func viewDidLoad() {
   super.viewDidLoad()
   self.tableView.register(FUISegmentedControlFormCell.self, forCellReuseIdentifier: FUISegmentedControlFormCell.reuseIdentifier)
}

override func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
   let cell = tableView.dequeueReusableCell(withIdentifier: FUISegmentedControlFormCell.reuseIdentifier, for: indexPath) as! FUISegmentedControlFormCell

   cell.valueOptions = buttonTitles.flatMap { $0.map { $0.value } }
   cell.keyName = "Priority"
   cell.value = myObject.priority  // String value in the valid options set: ["LO", "MED", "HI"]

   // MARK:  implement onChangeHandler
   cell.onChangeHandler = { newValue in
       myObject.priority = buttonTitles[newValue].first!.key  // lookup valid String value, from the buttonTitles array
   }

   return cell
}
