title: How to Share PDF file in all eligable and appear iOS app?
body: <p>I am using <code>UIActivityViewController</code> for sharing PDF file, I have applied all code successfully to share .Pdf file, and when I see sharing sheet option there I can share or send my PDF file like Facebook, Gmail, Print, Copy etc but in my iPhone there some app also where we can share PDF file like WeChat, Open in iBooks, open in Hike, open in chrome etc but these option not shown on my share list like this image.</p>

  <p>But when I use <code>UIDocumentInteractionController</code> then I saw all sharing option Facebook, Gmail, Wechat, open in iBooks, open in hike etc. All apps which support pdf shown as sharing option when I used <code>UIDocumentInteractionController</code>, show in below image.</p>
  
  <p>But I want to use <code>UIActivityViewController</code>, and want to see all options which support PDF file like Wechat , open in iBooks, open in hike. Like this image....</p>

  <p>So how can I do that using <code>UIActivityViewController</code>, which kind of <code>excludedActivityTypes</code> include in my pdf sharing file because I'm using almost all <code>excludedActivityTypes</code> like <code>UIActivityTypePostToFacebook</code>, <code>UIActivityTypeMessage</code> etc.</p>
