title: What is the best way to check if user can upload files?
body: <p>Im wondering what the best way to check if the input type="field" field is available to the user?</p>
  
  <p>At least iPhones and iPads does not allow the user to upload files, but rather than checking the user agent with backend code i'd like to hear what you think is the most minimalist solution?</p>
  
  <p>The purpose is to check if file upoads is available, if not, set display:none; for the whole div containing the form.</p>
  
  <p>Can this be done with only css? jQuery?</p>
  
  <p>I'd prefer a solution which not explicitely does not check if(iOS) but rather does a more generic check.</p>
  
  <p>Thank you in advance!</p>
