title: Core Text's Paragraph's space is too huge on iOS
body: <p>I used CoreText to render text as below:  </p>
  
  <blockquote>
    <p>Another very common typesetting operation is drawing a single line of text to use as a label for a user-interface element.<br>
    In Core Text this requires only two lines of code, one to create the line object with an attributed string and another to draw the line into a graphic context.<br>
    but it shows how to create an attributes dictionary and use it to create.</p>
  </blockquote>
  
  <p>obvious there're 3 paragraphs. and I use default <code>CTParagraphStyleSetting</code> so that the <code>ParagraphSpacing</code> and <code>ParagraphSpacingBefore</code> is set to 0 by default.  </p>
  
  <p>But the rendered result shows the space is too HUGE<br>

  <p>Any idea to reduce the paragraph space?</p>
