I knew it was something simple. Thanks all, NSNumber does the trick.

Or to put it another way, you can only put NSObjects in NSArrays.

I am trying to insert an int into an NSMutableArray,
but getting an
error.
My int is an instance variable of my controller
class. I am trying to
add the int to an instance variable NSMutableArray
of another class
(already properly instantiated) through this process
[myObject addItemToArray: myInt];
Which in turn calls this method:
- (void) addItemToArray: (id) newItem
{
[myArray addObject: newItem];
}
I get the following error in the debugger:
[NSCFArray addObject:]: attempt to insert nil
I know this is some stupid rookie mistake, that I am
missing some
fundamental understanding here, but could someone be
so kind as to
point out the flaw of sending an int directly in
such a manner?
