Answer 1

NSString *post=[[NSString stringWithFormat:@"command=%@&username=%@&password=%@",@"login",@"username",@"password"]stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding];

    NSMutableURLRequest *request=[NSMutableURLRequest requestWithURL:[NSURL URLWithString:@"http://www.blablabla.com"]];

   [request setHTTPMethod:@"POST"];

   [request setValue:@"x-www-form-urlencoded" forHTTPHeaderField:@"content-type"];
    [request setHTTPBody:[NSData dataWithBytes:[post UTF8String] length:strlen([post UTF8String])]];

   NSData *data=[NSURLConnection sendSynchronousRequest:request returningResponse:nil error:nil];

    id jsonobject=[NSJSONSerialization JSONObjectWithData:data options:NSJSONReadingMutableContainers error:nil];

    if ([jsonobject isKindOfClass:[NSDictionary class]])
    {

        NSDictionary *dict=(NSDictionary *)jsonobject;
        NSLog(@"dict==%@",dict);

    }
    else
    {

        NSArray *array=(NSArray *)jsonobject;
        NSLog(@"array==%@",array);
    }

Answer 2

Try this simple method....

- (void)simpleJsonParsing
{
    //-- Make URL request with server
    NSHTTPURLResponse *response = nil;
    NSString *jsonUrlString = [NSString stringWithFormat:@"http://domain/url_link"];
    NSURL *url = [NSURL URLWithString:[jsonUrlString stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding]];

    //-- Get request and response though URL
    NSURLRequest *request = [[NSURLRequest alloc]initWithURL:url];
    NSData *responseData = [NSURLConnection sendSynchronousRequest:request returningResponse:&response error:nil];

    //-- JSON Parsing
    NSMutableArray *result = [NSJSONSerialization JSONObjectWithData:responseData options:NSJSONReadingMutableContainers error:nil];
    NSLog(@"Result = %@",result);

    for (NSMutableDictionary *dic in result)
    {
         NSString *string = dic[@"array"];
        if (string)
        {
             NSData *data = [string dataUsingEncoding:NSUTF8StringEncoding];
             dic[@"array"] = [NSJSONSerialization JSONObjectWithData:data options:0 error:nil];
        }
        else
        {
             NSLog(@"Error in url response");
        }
    }

}
