How to create a new instance of an NSDocument with NSDocumentController?

Question

I tried

[[NSDocumentController sharedDocumentController] duplicateDocumentWithContentsOfURL:nil
                                                                            copying:NO
                                                                        displayName:nil
                                                                              error:NULL] ;

but it is not working. I have the error

typeForContentsOfURL:error: must be overridden for your application to support non-'file:' URLs.

Did you try like this below:-

   [[NSDocumentController sharedDocumentController]newDocument:self];

Thanks !! I was looking for the wrong keyword : `create` instead of `new` !! – Colas Oct 07 '13 at 13:06

I don't really know about the NSDocument+NSDocumentController machinery but here is my guess . Since I am answering my own question, please don't hesitate to comment or react.

    [[NSDocumentController sharedDocumentController] addDocument:[[Document alloc] initWithType:nil
                                                                                      error:NULL]] ;
