Difference between launch image and splash screen

Question

I was going through iOS Human Interface Guidelines.

It was mentioned as

1. Display a launch image that closely resembles the first sc

Answer 1

In iOS splash screen means when you provide any image named Default.png in the bundle and before executing the mainWindow it is just loading that image in the iPhone screen. So, Default.png image is considered as the Splash Screen in iPhone.

While you load the mainWindow in the iPhone application, you can assign any image that can be viewed in the screen in the specific size as given that is called the launch image.

So, launch image that is one which we provide run time when application launches and starting the main-window. And here launch image can be dynamically changed based on program written while Default.png / splash screen will be fixed for the application.

Please let me know if you still have any question?
