How to check if iOS can open a specified binary filetype?
<p>I need to create an iPhone app that will connect to an Amazon S3 bucket, where it will download potentially <em>any</em> type of binary file.  I am assuming that I could easily handle images, videos, web pages, and pdfs right from the app (or safari).  But is there a way to see if there are other apps that can support the downloaded file content-type?</p>

<p>And if iPhone has that application, then I could hand off the viewing to that other app.  Is such a scenario possible?  </p>

<p>Thank you.</p>
