Dear list,
I have an NSPersistentDocument subclass which encapsulates a project for the
user. When the user creates a new project, they specify a name and a location
on disk. I then want to create a new instance of my NSDocument subclass as if
it was saved exactly where the user wants it to be. I want to do this because
the app then creates additional files (which are managed by the project --
think Xcode) which are placed in the same location as the project file.
In the past I achieved this in a somewhat unsatisfactory way by just calling
newDocument: then saveDocument: and getting the user to immediately save the
document before the app does the rest of the setup steps. This was working, but
it does mean that the user is immediately presented with a save panel, which is
not so nice. I'd rather present a custom panel telling them to enter a project
name and a location on disk. Anyway, that aside, this scheme doesn't seem
robust to future OS implementations (maybe the saveDocument: behaviour changes,
for example). What I'd really like is an NSDocumentController method like
-(id)createDocumentAtURL:(NSURL*)aURL ofType:(NSString*)type
error:(NSError**)anError;
but that doesn't seem to exist.
Can anyone recommend a way to do what I want? In other words, to
programmatically create an NSDocument instance already saved on disk? This
behaviour is essentially what Xcode is doing when one creates a new project.
Best wishes,
Martin
