I do better than that - on the dealloc call, my code explicitly
deallocates it.
Meaning, I assume, in this containing class's -dealloc, you call
[editedRowName dealloc]? I don't think you want to do that; I don't
think you're supposed to call -dealloc yourself, but rather -release,
and let the system call -dealloc if necessary.

I'm writing a program that, in one table view, has the following
code:
id receivedName = [theDatabase itemAtIndex:editedRow] ;
editedRowName = [receivedName mutableCopy] ;
[receivedName release];
where "editedRowName" is defined as an NSMutableString.
[theDatabase itemAtIndex:editedRow]
Asks my database to return item "editedRow." The object at that
index is an NSString. For this function, the database would return
[theStringHere retain]
My code needs a mutable version of this string, so I make a
mutableCopy of it and release the old one, as to prevent a memory
leak.
OK, good...
However, when I do a "Run with performance tool: Leaks", it tells
me that, ever time this part of the code runs, it leaks a
"GeneralBlock-32" with the following information:
Category: CFString (store)
Event Type: Malloc
Responsible Library: Foundation
Responsible Caller: -[NSCFString mutableCopyWithZone:]
Does anybody know where this leak is coming from?
Do you [auto]release "editedRowName", the mutable instance? By
using the -mutableCopy: method, you are responsible for releasing
the result explicitly.
