Here is the Answer(you should convert your datetime to string) :-

        NSString *post =[NSString stringWithFormat:@"app_key=%@&signature=%@&timestamp=%@&user_id=%@&password=%@",appKEY,Signature,Datetime,UID,Password];

    NSData *postData = [post dataUsingEncoding:NSUTF8StringEncoding allowLossyConversion:YES];

    NSString *postLength = [NSString stringWithFormat:@"%d", [postData length]];

    NSMutableURLRequest *request = [[[NSMutableURLRequest alloc] init] autorelease];
    [request setURL:[NSURL URLWithString:@"Your URL"]];
    [request setHTTPMethod:@"POST"];
    [request setValue:postLength forHTTPHeaderField:@"Content-Length"];
    [request setValue:@"application/x-www-form-urlencoded charset=utf-8" forHTTPHeaderField:@"Content-Type"];
    [request setHTTPBody:postData];

    NSError *error;
    NSURLResponse *response;
    NSData *returnData=[NSURLConnection sendSynchronousRequest:request returningResponse:&response error:&error];
    if (error)
{
    NSLog(@"Error is %@",[error localizedDescription]);
}

    returnString=[[NSString alloc]initWithData:returnData encoding:NSUTF8StringEncoding];
    if(!returnString)
    {
        UIAlertView *erroralert = [[UIAlertView alloc] initWithTitle:@"Error" message:@"There is an error getting response" delegate:self cancelButtonTitle:nil otherButtonTitles:@"OK", nil];
        [erroralert show];
        [erroralert release];
    }
    else 
    {
        NSLog(@"%@",returnString);
    }
    SBJSON *json = [[SBJSON new] autorelease];
    NSMutableDictionary *dic = [[NSMutableDictionary alloc] initWithDictionary:[json objectWithString:returnString error:nil]];
