body: <p>I want to remove Gmail from my UIActivityViewController. Here is my following code:</p>
  
  <pre><code>ActivityViewController *activityVC = [[ActivityViewController alloc] initWithActivityItems:objectsToShare applicationActivities:nil];
  activityVC.completionWithItemsHandler = ^(NSString *activityType, BOOL completed, NSArray *returnedItems, NSError *activityError) {
      NSLog(@"%@", activityType);
  };
  
  NSArray *excludeActivities = @[@"com.google.Gmail.ShareExtension"];
  
  activityVC.excludedActivityTypes = excludeActivities;
  
  [self presentViewController:activityVC animated:YES completion:nil];
  </code></pre>
