Facebook login is not working In-app browser for iOS
<p>I'm using following script for login using Facebook JavaScript API.</p>

<pre><code>var permissions = [
    'email',
    'user_friends'
].join(',');

FB.login(function (response) {
    // if login was successful, execute the following code
    if (response.authResponse) {
        //Perform next set of methods
    }
}, {scope: permissions});
</code></pre>

<p>This is working in all browsers and in Android (this script is rendering inside an iframe). </p>

<p>But when a user open the login page in Facebook In-app browser for iOS, then the login is not working. Popup is not showing.</p>

<p>After spending some time to fix this, the issue is happening only when I include the login page in an iframe.</p>

<p>Anyone experienced the same issue?</p>
