title: How can I use iOS's standard red number badges within my app?
body: <p>I know that it's trivial to add a red number badge to an app's icon on the home screen. What's the best way to get a badge that looks like this within my app? There are some classes I've found online that can do this, such as <a href="http://www.claireware.com/blog_files/iphone_badge_view.html" rel="noreferrer">MKNumberBadgeView</a>, but none that I've found look completely right. Facebook, for example, implements red badges within the app perfectly as far as I can see. Did they just build their own badges by trial and error? Any suggestions would be appreciated.</p>
  
  <p>Thanks,</p>
