componentsSeparatedByString returns an NSArray, not an NSMutableArray.
You'll need to make a mutableCopy, like so:
NSMutableArray *listItems = [[[list componentsSeparatedByString:@","]
mutableCopy] autorelease];
If you don't autorelease your mutable array here, you'll have to
release it yourself later.

Hi Guys,
I'm trying to do this:
NSString *list = @"wrenches, hammers, saws";
NSArray *listItems = [list componentsSeparatedByString:@", "];
Which is straight out of the documentation and I want to use a
Mutable Array instead, but I get this warning:
warning: initialization from distinct Objective-C type
then I want to add an object like so:
[listItems addObject:newObject];
But when I run the program it halts and says the following:
-[NSCFArray addObject:]: mutating method sent to immutable object
Does anyone know what is going on?
Phil
