How to send in postJson an array like string without "" in Objective-c?

Question

I need send to my request server an array in parameters, but this can't be contained between "".

I need send to my server the key users with the array [2, 5, 6] value like this:

"users" : [2, 5, 6]

I'm trying do this but I only can get the array in format ( 2, 5, 6) or like this:

 "[2, 5, 6]"

This code only get the array with "":

NSMutableArray *array= [NSMutableArray arrayWithObjects:@"1", @"2",@"3",@"4", nil];
NSData *jsond = [NSJSONSerialization dataWithJSONObject: array options:NSJSONWritingPrettyPrinted error:NULL];
NSString *json = [[NSString alloc] initWithData:jsond encoding:NSUTF8StringEncoding];

How can I send my array in parameters in the correct format without ""?

Update your question with relevant code showing what you are printing and how is was created, and your printed it (to see the quotes). — rmaddy, Sep 16 '16 at 22:20
I'm updated my question with my code. Now I can show my array with "", but I can send this in parameters post json without "" — user3745888, Sep 16 '16 at 22:39
That code doesn't output what we're seeing. Where is "users" coming from? Can you send the actual code please? — TyR, Sep 16 '16 at 22:41
I had explained bad, "users" is the key of the dictionary that I want send to my server, but this questions is for convert the array to format [1,2,3] and add this array to the key "users" — user3745888, Sep 16 '16 at 22:48
Take the string, "[1,2,3]", and run it through NSJSONSerialization . Then you will have an NSArray. Add that to your NSMutableDictionary, under the key "users". I still don't quite know what you're doing but it sounds like maybe you're inserting JSON strings into things that should be holding arrays. The full code would help. — TyR, Sep 16 '16 at 22:50
down voted because the question is unclear, the sample code doesn't generate the output in the question, and also this Q is very similar to OP's other Q asked a few hours ago: http://stackoverflow.com/questions/39539360/how-to-get-an-array-type-1-2-instead-of-1-2-in-objective-c — TyR, Sep 16 '16 at 23:01

To get the output you need in question text try the following

NSDictionary *dict= @{@"users" : @[@1, @2, @3, @4]};
NSData *jsond = [NSJSONSerialization dataWithJSONObject:dict options:0 error:NULL];
NSString *json = [[NSString alloc] initWithData:jsond encoding:NSUTF8StringEncoding];

The output is {"users":[1,2,3,4]}
