FUIDurationPickerFormCell

@IBDesignable
public class FUIDurationPickerFormCell : FUIInlineValidationTableViewCell, FUIPropertyFormCell

A UITableViewCell subclass, which allows a user to read or enter a value, using a duration picker.

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 TimeInterval

And an onChangeHandler:

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

Optionally, the developer may provide

• minInterval: The minute interval to be used in the picker.
• isEditable: Indicates if the cell’s value may be modified. Defaults to true.

Color configuration:

Call setTintColor(_:for:) to configure tint color for disabled, normal, selected UIControlState. Setting tintColor is equivalent to call setTintColor(color, for: UIControlState.normal).

• disabled: Color to be used when control is disabled.
• normal: Color to be used when control is enabled.
• selected: Color to be used when control is selected.

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

 override func viewDidLoad() {
     super.viewDidLoad()
     self.tableView.register(FUIDurationPickerFormCell, forCellReuseIdentifier: FUIDurationPickerFormCell.reuseIdentifier)
     // ...
 }

 override func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {

     let cell = tableView.dequeueReusableCell(withIdentifier: FUIDurationPickerFormCell.reuseIdentifier, for: indexPath) as! FUIDurationPickerFormCell
     cell.keyName = "Duration"
     cell.value = myObject.eventDuration  // in seconds

     // MARK:  implement an onChangeHandler
     cell.onChangeHandler = { newValue in
        myObject.eventDuration = newValue
     }

     return cell
 }
