title: Change font color of UITextView
body: <p>I have a UITextView where the user can input text. Say the user has already inputted a value. How can I change the font color of that already typed text and future typed text to a different one with the click of a button?</p>
  
  <p>I already have it set up where I can change the color of the text but it only works if I choose a color BEFORE I start typing. After I start typing and I attempt to change the color, it doesn't do anything. </p>
  
  <p>I have this:</p>
  
  <pre><code>-(IBAction)changeInkColor:(id)sender
  {
      [inkTextField setTextColor:[UIColor greenColor]]; 
      inkTextField.text=@"text";
  }
  </code></pre>
  
  <p>and that actually works and displays "text" in green only if there is no text already in the view. However if I type something in and then hit this button, nothing happens.</p>
