title: Facebook deep linking/App link not working on iOS
body: <p>I am trying to open my app from facebook when I tap on the post I made from my app.</p>
  
  <p>I registered my app in developers.facebook.</p>
  
  <p>I enabled the deep linking in my facebook app settings.</p>
  
  <p>I have created the URL scheme for the app.</p>
  
  <p><strong>Note:My app is not published into app store. (Appple Appstore &amp; Facebook app center)</strong></p>
  
  <p>I tried the following ways: However the post is made successful but facebook is not opening my app when I tap on that post.</p>
  
  <p>One Way:</p>
  
  <pre><code>    // Create an object
      NSDictionary *properties = @{
                                   @"og:type": @"books.book",
                                   @"og:title": @"A Game of Thrones",
                                   @"og:description": @"In the frozen wastes to the north of Winterfell, sinister and supernatural forces are mustering.",
                                   @"books:isbn": @"0-553-57340-3",
                                   };
      FBSDKShareOpenGraphObject *object = [FBSDKShareOpenGraphObject objectWithProperties:properties];
  
      // Create an action
      FBSDKShareOpenGraphAction *action = [[FBSDKShareOpenGraphAction alloc] init];
      action.actionType = @"books.reads";
      [action setObject:object forKey:@"books:book"];
  
      // Create the content
      FBSDKShareOpenGraphContent *content = [[FBSDKShareOpenGraphContent alloc] init];
      content.action = action;
      content.previewPropertyName = @"books:book";
  
      FBSDKShareDialog *dialog = [[FBSDKShareDialog alloc] init];
  
      if ([[UIApplication sharedApplication] canOpenURL:[NSURL URLWithString:@"fbauth2://"]]){
          dialog.mode = FBSDKShareDialogModeNative;
      }
      else {
          dialog.mode = FBSDKShareDialogModeBrowser; //or FBSDKShareDialogModeAutomatic
      }
      dialog.shareContent = content;
      dialog.delegate = self;
      dialog.fromViewController = self;
      [dialog show];
  </code></pre>
  
  <p>Another Way:</p>
  
  <pre><code>   FBSDKShareLinkContent *content = [[FBSDKShareLinkContent alloc] init];
  
      content.contentURL = [NSURL URLWithString:@"https://developers.facebook.com"];
      content.contentTitle=@"TestSHare";
  
      FBSDKShareDialog *dialog = [[FBSDKShareDialog alloc] init];
  
      if ([[UIApplication sharedApplication] canOpenURL:[NSURL URLWithString:@"fbauth2://"]]){
          dialog.mode = FBSDKShareDialogModeNative;
      }
      else {
          dialog.mode = FBSDKShareDialogModeBrowser; //or FBSDKShareDialogModeAutomatic
      }
      dialog.shareContent = content;
      dialog.delegate = self;
      dialog.fromViewController = self;
      [dialog show];
  </code></pre>
  
  <p>Facebook is opening the app center page. But not my app. </p>
  
  <p>Does the deeplink works only when app is pubished ?</p>
  
  <p>Any reasons ?</p>
