objective-c: read an array create by json - objective-c

Question

I begin in Ios dev and I got some troubles to manipulate an array create by Json :
I call in my app a web Service which return me data :
{evenements =(
({
dateEvenement ={
1 = "01-01-2013";
2 = "02-01-2013";
3 = "03-01-2013";
4 = "04-01-2013";
};
idEvenement = 61;
nbrInvite = 1;
nomEvenement = "My event Name";
nomUtilisateur = "Lucas ";
}
),
);
}
I'm able to get all the values by the following code except for "dateEvenement" :
NSArray *msgList;
msgList = [ jsonResults objectForKey:#"evenements" ];
for (NSDictionary *evenements in msgList) {
for (NSDictionary *evenement in evenements ) {
NSString *idEvenement = [evenement objectForKey:#"idEvenement"];
NSString *nomUtilisateur = [evenement objectForKey:#"nomUtilisateur"];
NSString *nomEvenement = [evenement objectForKey:#"nomEvenement"];
NSString *nbrInvite = [evenement objectForKey:#"nbrInvite"];
NSArray *dates = [ evenement objectForKey:#"dateEvenement" ];
}
}
Can you help me for getting datas of "dateEvenement"

Answer 1

Well in your JSON the dateEvenement isn't an Array but a dictionary:
NSDictionary *dates = [ evenement objectForKey:#"dateEvenement"];
for(NSNumber *key in dates) {
NSString *dateString = [dates objectForKey:key];
NSLog(%# : %#, key, dateString);
}
As declared in your JSON example the key's for the dictionary are numbers, thus you should NSNumber object for the key type.
