Today App Extension Widget Tap To Open Containing App

EDIT: Ok, just a little correction here. I got it working with placing a button over the label just like suggested above and the following code:

- (IBAction) goToApp: (id)sender { 
    NSURL *url = [NSURL URLWithString:@"floblog://"];
    [self.extensionContext openURL:url completionHandler:nil]; 
  }

I linked it to a “Touch Up Inside” event. However, this also causes the app to launch when the user scrolls the Today view.

=======================================

I ran into the same issue. However, it seems that there is no solution for now since the release notes for the first beta of iOS 8 mention:

Known Issues: openURL does not work from an extension.

So I guess we will at least have to wait until beta 2.
