title: UITextView ruled line background but wrong line height
body: <p>I have a UITextView where the user can create notes and save into a plist file.
  I want to be able to show lines just like a normal notebook. The problem I have is
  that the text won't align properly.</p>
  
  <p>The image below explains the problem quite well.</p>

  <p>This is the background I use to create the lines like the Notes.app
  <img src="https://i.stack.imgur.com/zNFlt.png" alt="enter image description here"></p>
  
  <p>This is my code for creating the background for my <code>UITextView</code>:</p>
  
  <pre><code>textView.font            = [UIFont fontWithName:@"MarkerFelt-Thin" size:19.0]; 
  textView.backgroundColor = [UIColor colorWithPatternImage: [UIImage imageNamed: @"Notes.png"]];
  </code></pre>
  
  <p>I know that the <code>UIFont.lineHeight</code> property is only available in > iOS 4.x.</p>
  
  <p>So I wonder if there is another solution to my problem?</p>
