You're not calling [[numbers alloc] init];
at the point when you try to addObject you're sending a message to
nil, which is acceptable under Objective-C

I've got an object which has an NSMutableArray as an instance
variable. If, in one of my methods, I try to call
[myArray addObject:@"this is a test"]; (for example),
I get no error, but the object isn't added. If I try to do
[myArray objectAtIndex:0];
I get (null), and
[myArray count];
returns zero.
However, if I just declare the NSMutableArray inside one of the
methods of the object, everything works fine. However, this is
clearly not an optimal solution because the array is destroyed after
the method finishes executing.
I posted a sample project at http://danielrichman.com/tmp/NSMutableArray_Problem.tar.gz
.
Thanks!
