I am trying to send a HTTP-POST request to a key-value pair using the POST method, which in return send me a jSON response.

CODE

//[dictionnary setObject:@"tId" forKey:@"serialnumber"];
 NSMutableDictionary *dictionnary = [NSMutableDictionary dictionary];
         [dictionnary setObject:[NSString stringWithFormat:@"tId"] forKey:@"serialnumber"];
   [dictionnary setObject:[NSString stringWithFormat:@"tname"]  forKey:@"mobileimei"];
    [dictionnary setObject:[NSString stringWithFormat: @"tprice"] forKey:@"submerchantguid"];
    [dictionnary setObject:[NSString stringWithFormat: @"tquan"] forKey:@"transactionid"];
    [dictionnary setObject:[NSString stringWithFormat: @"tquan"] forKey:@"emailid"];
    [dictionnary setObject:[NSString stringWithFormat: @"tquan"] forKey:@"mobileno"];
    [dictionnary setObject:[NSString stringWithFormat: @"tquan"] forKey:@"signature"];
    [dictionnary setObject:[NSString stringWithFormat:@"tquan"] forKey:@"photo"];


 NSError *error = nil;
    NSData *jsonData = [NSJSONSerialization dataWithJSONObject:dictionnary
                                                       options:kNilOptions
                                                         error:&error];
    NSLog(@"Error is %@",error);

   NSString *urlString = @"MY_POST_URL/transaction/model/transactionsuccess";
    //NSString *urlString = @"http://yahoo.com";
    NSURL *url = [NSURL URLWithString:urlString];
    NSMutableURLRequest *request = [NSMutableURLRequest requestWithURL:url];
    [request setHTTPMethod:@"POST"];

    [request setHTTPBody:jsonData];
    NSURLResponse *response = NULL;
    NSError *requestError = NULL;
    NSData *responseData = [NSURLConnection sendSynchronousRequest:request returningResponse:&response error:&requestError];
    NSLog(@"request Error %@",requestError);
    NSString *responseString = [[NSString alloc] initWithData:responseData encoding:NSUTF8StringEncoding] ;
    NSLog(@"%@", responseString);

Please correct me with what is wrong in the code.I have also tried sending the details for all values using 

[dictionnary setObject:@"tId" forKey:@"serialnumber"];

format also. I am getting no error,still the expected jSON response is not achieved.Backend only intakes the information, and throws status as “0” OR “1”.Instead some weird output is being displayed, I suppose it is css script.

    You have error on the server side, you can not use the json directly you have to convert json to array json_decode firstly then use the values of the array

    this is how to convert the php json to array http://php.net/manual/en/function.json-decode.php

    Also the to return json you should format your php array again to JSON encode
