You are making a mistake of taking an array as dictionary. You are adding an array into array and you are treating this added array as a dictionary.

You need to only enumerate through your JSON array object..

If still not getting, post the full response, I will help you !!!

By seeing your JSON FROMAT.It is clear that is Array.So Please put your response json in to Array your other code is right.

Just Follow this

NSArray *jsonArray = YOUR_JSON_RESPONSE_AS_SHOWN_ABOVE
NSMutableArray * mainArray = [[NSMutableArray alloc] initWithArray:jsonArray];

for (int i = 0; i<mainArray.count; i++) {


    NSDictionary *BatchDict = [mainArray objectAtIndex:i];

    NSString * name = [BatchDict objectForKey:@"Name"];
    NSString * Ids = [BatchDict objectForKey:@"id"];

    [NameArray addObject:name];
    [IdArray addObject:Ids];
}

NSLog(@"so finally name array%@",NameArray);
NSLog(@"so finally Id array%@",IdArray);

It will work fine . . . .

All you have to do is to put JSONdata into dictionary.

For example like this:

NSDictionary *dictionary = [NSJSONSerialization JSONObjectWithData:data 
                                                           options:kNilOptions 
                                                             error:&error];

where data is your JSON object, then you can simply use

NSLog(@"Dictionary: %@", [dictionary description]);

Hope this will work for you.
