我正在使用Bootstrap创建网站，但一切正常，但是当我在iPhone上查看网站时，导航栏不会折叠。在Windows Phone上查看时，效果很好。
这是我标头的代码，有人可以看到为什么会这样吗？
<!DOCTYPE html>
<html <?php language_attributes(); ?>>
<head>
<title><?php wp_title( ' | ', true, 'right' ); ?></title>
<link rel="stylesheet" type="text/css" href="<?php echo get_stylesheet_uri(); ?>" />
<script src="http://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
