This way the views come up quicker. (Is this the right way? I found that having the viewcontroller load up the model objects would cause a large delay in the showing of the view?) So, even after having the models initialize in the appdelegate there is a delay in the first viewcontroller showing. So I guess I need a loading view/screen.
So the question is: how do I get the loading screen to come up without delay?
I've tried putting code into the applicationDidFinishLaunching as he first thing - figuring after everything got loaded it would hit the "[window addSubview:tabBarController.view];". Still had the delay - and never saw the splash screen come up.
Next I tried putting in the awakefromnib on the first viewcontroller - while it did seem to hit the viewdidload of the splash screen, nothing again came up.
So where do you put it?
Thanks!

All you have to do id add an image named Default.png to your project (this will be the picture of the loading screen, prefferrably 320 x 480). Then add (1); to your appdelegate.m in the applicationDidFinishLaunching function:
- (void)applicationDidFinishLaunching
UIApplication *)application {
(1); ///This tells XCode that you have a loading screen
// Add the tab bar controller's current view as a subview of the window
[window addSubview:tabBarController.view];
[window makeKeyAndVisible];
}
