    hi Dipin, my logintodb.php is below:

    $host = “localhost”;
    $user = “root”;
    $pass = “root”;

    $r = mysql_connect($host, $user, $pass);

    if (!$r) {
    echo “Could not connect to server\n”;
    trigger_error(mysql_error(), E_USER_ERROR);
    } else {
    echo “Connection established\n”;

    echo mysql_get_server_info() . “\n”;
    $r2 = mysql_select_db($db);

    if (!$r2) {
    echo “Cannot select database\n”;
    trigger_error(mysql_error(), E_USER_ERROR);
    } else {
    echo “database selected\n”;
    $result=mysql_query(“select username,pass from login where username=’$us’ and pass=’$pw'”);

    if($row[“username”]==$us && $row[“pass”]==$pw)
    echo ‘{“success”:1}’;

    What do you mean by setting tab bar controller as the root view controller. Does it mean selecting this as a initial view controller? Are they same concept? How do you set a view controller as a root view controller? Could you provide sample code, please?
