Today App Extension Widget Tap To Open Containing App

Question

I\'ve implemented a Today widget for my application +Quotes which displays the day\'s quote within the notification center with the help of these Apple Docs. What I\'d like

The answer by @sunseeker is the good one but it is "hidden" in the comments. And as the accepted answer says that this isn't possible, it may mislead visitors.

this code works:

- (IBAction)launchHostingApp:(id)sender
{
  NSURL *pjURL = [NSURL URLWithString:@"hostingapp://home"];
  [self.extensionContext openURL:pjURL completionHandler:nil];
}

I'm using Xcode 6.0 (6A215l) with Yosemite Beta 1.

And like Apple says in Handling Commons Scenarios :

An extension doesn’t directly tell its containing app to open; instead, it uses the openURL:completionHandler: method of NSExtensionContext to tell the system to open its containing app. When an extension uses this method to open a URL, the system validates the request before fulfilling it.
