osx - Delete selected token from NSTokenField -

I am trying to delete the selected tag action from a button to remove the selected token in NSTokenField.

  @IBAction func deleteSelectedTag (From: AnyObject) {fieldEditor = (tagTokenField.cell)! NSCell). FieldEditorForView (tagTokenField) if fieldEditor? .selectedRanges.count & gt; 0 {fieldEditor.delete}}  

Any code does not remove this selected token code?

The only way I got this to do this was to edit the array that NSTokenField The value was bound to use the range selected by the field editor:

  @IBAction func deleteSelectedTag (From: AnyObject) {fieldEditor = (tagTokenField.cell)! NSCell) .fieldEditorForView (tagTokenField) if the field sender? .selectedRanges.count & gt; 0 {Range = Field Sender !! Selected Rings first! NSRange fieldEditor! .setSelectedRange (NSMakeRange (0, 0)) // None of the selected selected tags! After the test  

after the test, I found that the selected range is always location . > Gives an NSRN with token index and length number of selected tokens at least I found no way to select non closest tokens in Nstikonfield.
