YESto force the first responder to resign, regardless of whether it wants to do so.
YES if the view resigned the first responder status or
NO if it did not.
This method looks at the current view and its subview hierarchy for the text field that is currently the first responder. If it finds one, it asks that text field to resign as first responder. If the
force parameter is set to
YES, the text field is never even asked; it is forced to resign.
