Use this

NSString *str=@"{"Data": [{"ID":"1","Name":"Raj"},{"ID":"2","Name":"Rajneesh"}]}";

NSMutableDictionary *dict=[NSJSONSerialization JSONObjectWithData:[str dataUsingEncoding:NSUTF8StringEncoding] options:kNilOptions error:nil];

NSMutableArray *dataArr=[dict valueForKey:@"Data"];
for (NSDictionary *userData in dataArr) {
    NSLog(@"Id:%@ Name:%@",[userData valueForKey:@"ID"],[userData valueForKey:@"Name"]);
}
