title: How to pass text to 3rd party app in iOS
body: <p>My app generates some sort of text information.</p>
  
  <p>User presses button like "Share" in my app and after that pops up a windows with a list of installed applications or only apps which can recieve string parameter. After that, user selects, for example, "Mail" app and then it is opened with the new email message and with a given text from my app. Or user selects Skype app and then it is opened with a given text.</p>
  
  <p>How could those scenarios be implemented in iOS?</p>
  
  <p>PS: I already saw similar behavior in Android app (via <code>Intent</code> extras).</p>
  
  <p>UPDATE: I posted the answer below that works for me (via UIActivityViewController) exactly how I need.</p>
