title: UITextView with custom autocorrect
body: <p>I want to implement a UITextView with a custom source for autocorrect values.
  What I exactly want to do, is to provide the user a autocorrect value for hash tags, so as soon as the user enters "#" and some letters, the autocorrect should provide some of the famous hash tags as autocorrect value.</p>
  
  <p>BUT: <strong><em>I don't want to implement this for UITextField</em></strong>. I found some tutorials and blogs about a custom autocorrect for UITextField, but I want/must use a UITextView because the user should be able to enter multiline text. Also, the tutorials only provide some sort of autocorrect for single word values, like e-mail addresses and so on..</p>
  
  <p>The autocorrect should work like the buildin autocorrect just like you know from the SMS app, but with my own set of autocorrect values.</p>
  
  <p>Does somebody know a component or something like that which could me provide such a feature?</p>
  
  <p>Thx in advance!</p>
