UIPrerenderedIcon glossy problem

i have a problem. When I want to undo the glossy stile of the App Icon, the Apple Documentation http:开发者_如何学编程//developer.apple.com/library/ios/#documentation/general/Reference/InfoPlistKeyReference/Articles/iPhoneOSKeys.html#//apple_ref/doc/uid/TP40009252-SW1 says, that there is a UIKit Key for that.

I tried to find this Key (UIPrerenderedIcon) in the Info.plist file of my Application, but I couldn't find it anywhere.

I use XCode 3.2.1 and iOS 3.0.

I guess that this key can only be used in an higher SDK, am I right?

Thank you in advanced for your response

If you are having this problem in iOS 5, as per Alex Stone's Answer, you have too edit the plist it in 2 places.

No, that key is available on all OS so you must be able to set it. In editor that key is named "Icon already includes gloss effects" - try finding it.

P.S. If I remember correctly Apple requires newly submitted apps to be built with sdk version at least 4.0 and it is generally a good idea to use the latest sdk version to build you app

For those using Xcode 4.2 or later, it will add this key automatically within the 'Icon files' group when you add a new icon. To fix, simply remove the key you added, expand the 'Icon files' group and set the flag to YES in there instead.
