I have developed an application with the new LaunchImage.xib feature of Xcode 6. This LaunchImage is simply a blank view with the color of the upcoming rootViewController. This works really fine for normal application startup.
The application can also be started with the Open In... option when tapping on a file in other applications (such as dropbox, or a mail attachment) and the given file is then processed in AppDelegate.didFinishLaunchingWithOptions. This may take some time depending on the size of the file. For that kind of application start I would like to show an alternate LaunchImage which informs the user that the file is being processed.
What I have seen so far is that I can only have one LaunchImage.xib and there is no way to work with a custom class to execute some code in appDelegate such as simply showing/hiding some labels on that screen.
Are there any ideas on how I can accomplish this?
