title: Unable pass NSString into NSMutableAttributedString?
body: <p>I want to create a display that shows a heading, sub-headings, an embedded image, and regular text (somewhat similar to a wikipedia style page). I have my heading, sub-headings, image, and regular text all in strings.  I understand an AttributedString is the best way to achieve my desired formatting.  What I cannot figure out is how to create the AttributedString from my pre-existing strings.</p>
  
  <pre><code>displayText = [[NSMutableAttributedString alloc] initWithAttributedString:@"%@ \n %d - %@", self.currentInstance.name, self.currentInstance.number, self.currentInstance.image];
  textView.attributedText = displayText;
  </code></pre>
  
  <p>I'm new so I'm sure it's something basic I am doing wrong.  I appreciate any help.</p>
