How to skip blank window during loading while UIPageViewController loads its first VC?

Question

My app load cycle shows the LaunchScreen.StoryBoard VC, but then for a second or two it displays the blank window before it displays the first VC in my UIPageViewController which is ugly UI. Is there a way I can show the LaunchScreen over the window (i.e. is there a method on window I can set in my appDelegate) so it seemly transitions from Launchscreen to the first VC?

Answer 1

A friend helped me with this...because the content that I was displaying in my UIPageViewController's VC's was derived via an asynchronous thread (NSXMLParser)...this delay time was what was interrupting my UI and displaying the window prior to the first VC.

I simply copied and pasted my LaunchScreen.StoryBoard into my Storyboard as a separate VC (and subclassed and added a storyboard ID), then in my UIPageViewController I loaded this new VC in viewDidLoad until my async call from NSXMLParser came back and displayed my first VC.
