[theCountries setValue:[NSMutableArray arrayWithObjects:@"AAABBB",
@"AABBB", @"AAACCC", nil] forKey:@"A"];
[theCountries setValue:[NSMutableArray arrayWithObjects:@"BBBAAA",
@"BBBBBBBB", @"BBBCCC", nil] forKey:@"B"];
[theCountries setValue:[NSMutableArray arrayWithObjects:@"CCCDDD",

[theCountries setValue:[NSMutableArray arrayWithObjects:@"T", nil] forKey:@"T"];
myKeys = [[NSArray alloc]init];
myKeys = [theCountries allKeys];
}
@end
Please tell me the binding connections I must make so that I see the Keys of
"theCountries" (i.e. myKeys) in the drop-down of countryCombo.
I tried using NSArrayController but could not get it right. Please guide me.
(Also, is there a way to reduce the four theCountries setValue: statements to
one?)
