The next step is to figure out how to move the pieces into their final positions smoothly. Running in the simulator, you should now see the pseudo-screen fade away after briefly appearing on screen. Tagging and selecting views like this allows you to construct a launch screen nib and manipulate it after launch, and the possibilities for how you animate it are endless! Note the viewWithTag() call - this is the main trick behind the entire illusion. ![]() Animate parts of this pseudo launch screen away, and remove the view.When the app finishes launching, paint an identical-looking view - a pseudo launch screen - over the app.Display the static launch screen while launching.In order to "animate" a launch screen, we'll create a three-step illusion: Tasks like adding borders, rounding corners, etc that you would usually place in view code are unavailable here - we must construct this screen entirely in Interface Builder. When using a storyboard or nib, note that you can't write any view code to accompany it. Due to this restriction, you're only allowed to use three types of file for a launch screen: A image, storyboard, or a nib (*.xib) file These screens are completely static for a reason: Apple doesn't want you running code or performing any CPU-intensive tasks while the app boots. Once the app loads, the screen fades out, revealing your app UI. A launch screen is a very simple visual that iOS displays while loading an app. ![]()
