title: UITextView where should I set color and font for for attributed string
body: <p>When I use UITextView in storyboard, I can select text as attributed string and set its attributes like color, font and other attributes. And when I set <code>textView.text = @"my string"</code> in code it show up as I set.</p>
  
  <p>My question is if I want to do this in code, what would be equivalent to this storyboard attributes setting? From document <a href="https://developer.apple.com/library/ios/documentation/UIKit/Reference/UITextView_Class/index.html#//apple_ref/occ/instp/UITextView/text" rel="nofollow">https://developer.apple.com/library/ios/documentation/UIKit/Reference/UITextView_Class/index.html#//apple_ref/occ/instp/UITextView/text</a> I see some property i.e. textColor, font, but lack of some property that I can set like line-height.</p>
