FUIDurationPickerFormCell

public class FUIDurationPickerFormCell: FUIInlineValidationTableViewCell, FUIPropertyFormCell

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

FUIDurationPickerFormCell

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.

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(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
 }
