Hello...
Sorry about that. I didn't actually re-read the documentation of
NSFileWrapper before posting that. I was looking at someone else's
code from an application that works with infomation stored in
ProjectBuilder projects (which are packages), and in part of its
loadFileWrapperRepresentation:ofType: it did this:
NSString *windowName = [[wrapper filename] lastPathComponent];
and I assumed that the NSFileWrapper method filename was similar to
NSDocument's fileName method. It's actually somewhat amusing that the
above code works the way the author intended...
Speaking of NSDocument's fileName method, it does provide the full
path, and it is set before the loadFileWrapperRepresentation:ofType:
method is called (at least it is in 10.2.x, and probably didn't
change in 10.3). So if your class is an NSDocument subclass, you
should be able to get the path by calling [self fileName] within the
loadFileWrapperRepresentation:ofType: method.
Hopefully that works better than my last suggestion :)

I'd already looked at -filename, but the comment next to its
declaration in NSFileWrapper.h says:
The filename is best thought of as the last known actual file name
of the wrapper. [...] It is just a filename, not a full path. Its
extension indicates its type.
Any other possibilities?

Anyway, the NSFileWrapper method
- (NSString *)filename;
should return the path of the file wrapper.
My document package class has a NSFileWrapper passed to
-loadFileWrapperRepresentation:ofType:. This is fine except that I
need to determine the file path for some of the files within the
package (images, etc.) since methods in other classes expect
either a NSURL or a NSString containing the full path.
How can I determine, at the very least, the base path associated
with the document's file wrapper?
