Returns the current field editor for the control.
- macOS 10.0+
The field editor for the current control, or
nil if the receiver does not have a field editor.
When the receiver is a control displaying editable text (for example, a text field) and it is the first responder, it has a field editor, which is returned by this method. The field editor is a single
NSText object that is shared among all the controls in a window for light text-editing needs. It is automatically instantiated when needed.
