title: How to share to Facebook (iOS)
body: <p>I'm trying to share a photo to Facebook using the Open Graph API. I was unsure of how to share a photo so I'm starting off with code to just post a like. So far I have the following code:</p>
  
  <pre><code>        // Create an object
          NSDictionary *properties = @{
                                       @"og:type": @"myObject",
                                       @"og:title": @"title",
                                       @"og:description": @"description",
                                       };
          FBSDKShareOpenGraphObject *object = [FBSDKShareOpenGraphObject objectWithProperties:properties];
  
  
          // Create an action
          FBSDKShareOpenGraphAction *action = [[FBSDKShareOpenGraphAction alloc] init];
          action.actionType = @"og.likes";
          [action setObject:object forKey:@"myObject"];
  
          // Create the content
          FBSDKShareOpenGraphContent *content = [[FBSDKShareOpenGraphContent alloc] init];
          content.action = action;
          content.previewPropertyName = @"myObject";
  
  
          [FBSDKShareDialog showFromViewController:self
                                       withContent:content
                                          delegate:nil];
  </code></pre>
  
  <p>I created a <strong>custom</strong> graph object on Facebook "myObject" and am trying to share or like this publicly on Facebook. I would love any help on this, when this code runs nothing shows up. Ideally I would like to add a photo to this object and be able to share it with a callback link to either my site (and eventually the app)!</p>
