Can the value part of a key-value pair in an NSMutableDictionary be a
literal NSString, like @"name"?
It would seem so, because this works or at least doesn't crash:
NSMutableDictionary *bobo;
bobo = [[NSMutableDictionary alloc] init];
[bobo setValue:@"root" forKey:@"name"];
However, I have a class derived from NSMutableDictionary, and it is
crashing when I try to do the same thing:
@interface myClass : NSMutableDictionary {
}
@end
myClass *tree;
tree = [[myClass alloc] init];
[tree setValue:@"root" forKey:@"name"];
Why does that crash when the first does not? Are subclasses required
to have member variables, or can they just have new functions? Mine
don't have any variables, maybe that is the problem?
Thanks for any replies!
Bob
