How to send recursive json request with nsmutableurlrequest in ios?

Question

in iOS to create this

"{
"email":string, 
"password":string
}"

json request body, i am passing the nsdata that i create from the string

email=myname@domain.com&password=mypassword

to the setHTTPBody method of the NSMutableURLRequest.This works fine im ok with this.

But what if i want to create this

"{
"post":
       {
        "title":string,
        "room_id":int,
        "content":string,
       }
}"

json request body? i tried to make some string combinations to solve this recursion but didnt work out really. I also checked the methods of NSMutableURLRequest but i couldnt find something related to solve this.

edit:

This creates the post as it should be its fine, but i need an equivalent to the string email=myname@domain.com&password=mypassword for the recursive case. When i send the data as it should be it does not work. When i send as the string that i provided it works.

NSString *usertoken =  [appDelegate token];
NSString *posttopic = @"111testtopic";
NSString *postbody =  @"111testbody";

NSDictionary *dict = @{@"post":@{@"title":posttopic,@"room_id":@"246",@"content":postbody}};
NSData *body = [NSJSONSerialization dataWithJSONObject:dict
                                               options:NSJSONWritingPrettyPrinted
                                                 error:nil];



NSString *postLength = [NSString stringWithFormat:@"%d", [body length]];
NSMutableURLRequest *request = [[NSMutableURLRequest alloc] init];

//send the post
NSString *urlstring = [NSString stringWithFormat:@"http://mydomain.com/posts.json?auth_token=%@", usertoken];
[request setURL:[NSURL URLWithString:urlstring]];
[request setHTTPMethod:@"POST"];
[request setValue:postLength forHTTPHeaderField:@"Content-Length"];
[request setValue:@"application/x-www-form-urlencoded;charset=UTF-8" forHTTPHeaderField:@"Content-Type"];
[request setHTTPBody:body];



NSURLResponse *response;
NSData *POSTReply = [NSURLConnection sendSynchronousRequest:request returningResponse:&response error:nil];

Try this

NSDictionary *dict = @{@"post":@{@"title":string,@"room_id":int,@"content":string}};
NSData *body = [NSJSONSerialization dataWithJSONObject:dict 
                                               options:NSJSONWritingPrettyPrinted 
                                                 error:&error];

the idea is to use some nested dictionaries to describe your json and serialize them to get your jsonData to pass to the request.

This creates the post as it should be its fine, but i do not provide nsdata obtained from the string – onuryilmaz Feb 07 '13 at 13:27
