dark screen on iPhone 3GS

Question

I'm having problem with my application on iPhone 3GS. I've created a little game, that's working fine on iPhone 3G. But apple rejected it. They've told me, that the screen is too dark and everything's hard to see because of it. Do you have any ideas what could cause that? Thanks for every reply.

I'm sorry but I'm not allowed to post images here directly, it's there.

Looks like something might be changing your opacity on your view. And as your opacity goes down, your window or underlying view's black background shows through.

Of course, it could also be a view on top that is black and has its opacity changed so it doesn't display the view below.

I could go on and on with different scenarios that could cause this. You have the code and you need to map out your view hierarchy, including the MainWindow, and determine which one has a black or dark background (or foreground) and then see how that is bleeding through.

Once you know that, it will be a lot easier to figure out why it has a problem on some devices/Simulator but not on your iPhone.
