I get no error, but the object isn't added. If I try to do
[myArray objectAtIndex:0];
I get (null)
That's a tip-off that the array pointer is nil, by the way — -
objectAtIndex: *never* returns nil, because it's not legal to store
nil values in an NSArray. (Same goes for objectForKey: in
NSDictionary.)
-[NSDictionary objectForKey:] returns nil if the specified key does
not have an associated value in the dictionary.
