title: How to set bold to a label without disturbing the font size and family names?
body: <p>I want to set the selected label to appear bold without implementing the font family-bold version.
  Ex:-
  the default way to set bold is as follows</p>
  
  <pre><code>UIFont *myFont = [UIFont fontWithName:@"Helvetica-BoldOblique" 
                                   size:[UIFont systemFontSize]];
  </code></pre>
  
  <p>But i want to change the font weight(i.e BOld, Italic or Underline) only. without calling the "fontWithName".</p>
  
  <p>Thanks in advance</p>
