title: What is the default line spacing in UITextView
body: <p>I want to increase the default line spacing in <code>UITextView</code> by 10 units.</p>
  
  <p>Here's how I am doing:</p>
  
  <pre><code>NSDictionary *attributesDictionary;
  NSMutableParagraphStyle *paragraphStyle = [[NSMutableParagraphStyle alloc] init];
  paragraphStyle.lineSpacing = 30;
  
  attributesDictionary = @{NSParagraphStyleAttributeName : paragraphStyle , NSFontAttributeName: cellFont};
  
  [str addAttributes:attributesDictionary range:NSMakeRange(0, str.length)];
  bodyTextView.attributedText = str;
  </code></pre>
  
  <p>So what is the default value that I should add 10 with and set it the linespacing?</p>
