how to change the background of an iphone app when it launches?

Question

Everything is in the title but I have to make myself clear :

I don't mean : how to automatically change the background of the app once it has finished launching.

What I mean is : when you first launch the app, before the first view is loaded by the iphone there is a black screen. Is it possible to change this black screen which I get when waiting for the first view to appear? I'd like to put a picture instead.

Thanks!
John

You need to set a Default.png and a Default@2x.png (for retina) and all the work is done for you. Or if you have payed to be a developer, download xcode 4 gm, and you can double click on the loading screen area and you can have it named what ever you wanted.

You must specify Launch image http://developer.apple.com/library/ios/#documentation/General/Reference/InfoPlistKeyReference/Articles/iPhoneOSKeys.html%23//apple_ref/doc/uid/TP40009252-SW9

Answer 4

You can add Default.png and it's variations to your project. This image will be displayed as splash screen during application startup (before the first view is loaded).

Just add a picture called "Default.png" to the project (size of the iPhone screen) and it'll automatically appear.
