title: Find out if an NSDate is today, yesterday, tomorrow
body: <p>With the iOS SDK I need to find an easy and secure way to see if an NSDate is today, yesterday, tomorrow. What I'm looking for is something like this in pseudo code:</p>
  
  <pre><code>NSDate *myDate = someDate;
  if ([myDate isTomorrow]) {
      NSLog("Tomorrow"); 
  }
  </code></pre>
  
  <p>How would you solve it?</p>
