title: Apple Watch and openParentApplication in background
body: <p>I am implementing a apple watch. In my extension of the Watchkit i use the method to communicate to the "main app".</p>
  
  <pre><code>    [WKInterfaceController openParentApplication:applicationData reply:^(NSDictionary *replyInfo, NSError *error) {}];
  </code></pre>
  
  <p>According to apple <a href="https://developer.apple.com/library/prerelease/ios/documentation/General/Conceptual/WatchKitProgrammingGuide/DesigningaWatchKitApp.html#//apple_ref/doc/uid/TP40014969-CH3-SW1">documentation</a>, the app can handle the request in background.</p>
  
  <pre><code>When you call the openParentApplication:reply: method, iOS launches or 
  wakes up the parent app in the background and calls the
  application:handleWatchKitExtensionRequest:reply:method of its app delegate.
  </code></pre>
  
  <p>However my app always became active, even if i have no code inside the method, <strong>handleWatchKitExtensionRequest</strong></p>
  
  <p>Any tips if it´s possible?</p>
  
  <p>Thanks in advance</p>
