title: Native Facebook app does not open with Facebook login in iOS 9
body: <p>I have updated iPhone 6 plus to iOS 9 beta and trying to perform Facebook login but each time its presenting UIWebView with Facebook login form. </p>
  
  <p>I have Facebook sdk </p>
  
  <pre><code>FB_IOS_SDK_VERSION_STRING @"3.24.0"
  FB_IOS_SDK_TARGET_PLATFORM_VERSION @"v2.2"
  </code></pre>
  
  <p>And I am using following methods to perform Facebook Login </p>
  
  <pre><code>    NSArray *permissions = @[@"email",@"user_birthday",@"public_profile"];
  
  
       FBSessionStateHandler completionHandler = ^(FBSession *session, FBSessionState status, NSError *error) {
           [self sessionStateChanged:session state:status error:error];
       };
  
       if ([FBSession activeSession].state == FBSessionStateCreatedTokenLoaded) {
       // we have a cached token, so open the session
           [[FBSession activeSession]openWithBehavior:FBSessionLoginBehaviorUseSystemAccountIfPresent
                                   fromViewController:nil
                                    completionHandler:completionHandler];
       } else {
  
       [self clearAllUserInfo];
      [[NSURLCache sharedURLCache] removeAllCachedResponses];
  
       // create a new facebook session
       FBSession *fbSession = [[FBSession alloc] initWithPermissions:permissions];
       [FBSession setActiveSession:fbSession];
       [fbSession openWithBehavior:FBSessionLoginBehaviorUseSystemAccountIfPresent
                fromViewController:nil
                 completionHandler:completionHandler];
       }
  </code></pre>
  
  <p>I have following setting under plist file</p>
  
  <pre><code>    &lt;key&gt;LSApplicationQueriesSchemes&lt;/key&gt;
      &lt;array&gt;
          &lt;string&gt;fbapi&lt;/string&gt;
          &lt;string&gt;fbapi20130214&lt;/string&gt;
          &lt;string&gt;fbapi20130410&lt;/string&gt;
          &lt;string&gt;fbapi20130702&lt;/string&gt;
          &lt;string&gt;fbapi20131010&lt;/string&gt;
          &lt;string&gt;fbapi20131219&lt;/string&gt;
          &lt;string&gt;fbapi20140410&lt;/string&gt;
          &lt;string&gt;fbapi20140116&lt;/string&gt;
          &lt;string&gt;fbapi20150313&lt;/string&gt;
          &lt;string&gt;fbapi20150629&lt;/string&gt;
          &lt;string&gt;fb-messenger-api20140430&lt;/string&gt;
          &lt;string&gt;fbauth&lt;/string&gt;
          &lt;string&gt;fbauth2&lt;/string&gt;
     &lt;array&gt;

  <p>Please let me know what I am missing here. First it is checking for <code>iPhone device Setting-&gt; Facebook credentials</code> but never open Facebook app for login. Seems it does not recognize Facebook app installed on device.</p>
