title: Reload application data when the app comes into foreground?
body: <p>I'm new to iPhone development. I'm building an app that loads data from a local sqlite3 DB in</p>
  <pre><code>-   (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {   
  </code></pre>
  <p>When I tap the iPhone button and put it in the background and then I recall it I see (as normal) the app in the same way I left it. What I would like to do is, when it comes in the foreground, to reload data as if it was called from scratch.</p>
  <p>Which is the correct way to do it?<br />
  Thanks in advance.</p>
