Show a splash screen while loading a view controller from another view controller

I have an app that opens with a splash screen (Default.png), then loads the first view (ViewController1) in a navigation controller. Straight away, an instance of ViewController2 (VC2) is created, and pushed onto the navigation controller:

[self.navigationController pushViewController:VC2 animated:NO];

So when I run the app, the default image is displayed, then the view of ViewController1 is briefly displayed until ViewController2 is loaded (and then displayed).

How can I stop the brief display of ViewController1? Can I extend the display of Default.png until VC2 is displayed, or cover ViewController1 with the Default.png image until VC2 shows?

Thanks so much.

you can add a UIImageView with splash image on [window addSubview:splashImage]; just before executing the code [self.navigationController pushViewController:VC2 animated:YES]; and then remove it in VC2's viewDiDAppear - Saurabh Passolia

If the only thing you want to do is to show VC2 without showing VC1, in the viewDidLoad method of your VC1 you can do self.view.hidden = YES; then push the VC2 without animation

I think in your case, you want VC2 to be your starting point with VC1 as your ad-hoc splash screen. The default.png images should be a way to mirror the look of your app to give the impression your app is starting and working faster than it may appear. (This is taken from Apple's HIG)

You may want to consider making VC1 your new splashscreen/loading screen. You could make it into a simple waiting or loading page then load VC2 once everything in your app has been taken care of. Default.png could be an image of the loading screen and would give the impression your app is loading right away.

There are many differing opinions of how to approach this issue. You will ultimately have to decide which method is best for you and your application.

One final thought, you could load directly to VC2 and just present a loading progress view. I have used MBProgressHUD to lock the user out while I load information or perform tasks they need to wait for. This could be another option. Hope this information helps.

You can add a UIImageView to VC1 with Default.png, then remove it in viewDidDisappear:.

I don't think you can modify the Default.png behaviour. I would suggest you create an UIImageView in ViewController1 with Default.png as its image. Give it the exact same size as the screen and add it as a subview that completetely covers it. That way you will see Deafult.png twice and after it will go to ViewController2
