Image being loaded before app main method is called

I have an ipad app where I am seeing an image displaying briefly before the app starts (image is part of bundle).

My guess is that this is some wrong wiring of a xib file, but even when I set a breakpoint at the beginning of the 开发者_高级运维main method, the image still appears before this point is reached.

Resetting the simulator does not help, and the scenario occurs on a device too.

Mmmm is the image named Default.png ?

I just don't see an other explanation for this problem ^^

By the way, I just don't use Interface Builder to avoid this kind of strange problems ^^
