title: how to retrieve and handle remote push notification content in iOS app
body: <p>I was trying to fetch remote notification info when the app was not running,so I was told that I can get from :</p>
  
  <pre><code>UILocalNotification *localNotification  = [launchOptions 
                     objectForKey:UIApplicationLaunchOptionsRemoteNotificationKey] 
  </code></pre>
  
  <p>in method:</p>
  
  <pre><code>- (BOOL)application:(UIApplication *)application 
                 didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
  </code></pre>
  
  <p>,but still can't get info.</p>
  
  <p>Then I use alertView to show the info on iPhone(launch without Xcode),still can't get the info.</p>
  
  <p>Any other issue would cause this? Please let me know if you have any ideas.</p>
