Oh so the very first return value from a Dictionary is not actually a
string?
NSString *itemA = [DictionaryA valueForKey:@"FirstProcessIdentifier"];
I've check the apple document, valueForKey returns an ID... so it return an
object? how do I proceed?
If i cast it as NSString it gives me an error.
Thanks,
John
