title: Data passing between view controllers not working
body: <p>Property in my AppDelegate.h: <code>@property (retain, nonatomic) NSString *bmiShared;</code>.
  <em>(It is synthesized in my <code>AppDelegate.m</code>.)</em></p>
  
  <p>I have <code>AppDelegate.h</code> imported in both View Controller header files. I also have <code>AppDelegate *appDelegate</code> in each header.</p>
  
  <p>In both implementation files <em>(<code>ViewController.m</code> and <code>TipsViewController.m</code>)</em> I have:</p>
  
  <pre><code>appDelegate.bmiShared = bmiView.text;
  appDelegate = [[UIApplication sharedApplication] delegate];
  </code></pre>
  
  <p>I have no idea what I'm doing wrong when passing the data over. I want the <code>floatValue</code> of <code>bmiView.text</code> to be available for use in my <code>TipsViewController</code> so that if the <code>floatValue</code> of <code>bmiView.text</code> is a certain amount, it will show the correct information in my <code>TipsViewController view</code>. I am using Storyboards if that makes any difference.</p>
