Thanks about the memory leaks and about the allocating memory and
stuff. And I thought that might be my problem but I am not sure how to
actually use that method. The documentation was very vague in my
opinion.

Here you're over-retaining an NSArray. This won't do anything if
you're using GC, but if you're not, then you've created a memory leak.
NSString *string;
string = [NSString init];
Never initialize a variable without allocating it memory first.
string = @"Main Category";
Here you've overwritten a variable you just (incorrectly)
initialized. If all you want is a string, then you can do this:
NSString *string = @"Main Category";

The NSTableView is not being populated at all... No rows, and
nothing else....
Did you remember to set the table view's data source?
