Icon already includes gloss effects
iOS 5 has anew "Icon Files (iOS 5)" key in the Info.plist file. Make sure the "Icon already includes gloss effect" boolean in that dict is set to "YES" too. You may need to clear your build folder before the changes take effect in the simulator. It takes a lot of troubleshooting to get it to work on older projects, so you might try erasing the root level key.
First Settings in a your project info-list set key Icon already inculdes gloss effects to YES Boolean value like below screen shot:
after try project Target settings tick the checkbox in the summary tap in the App Icons sectionlike below screen shot:
it's worked for me!
Welcome in Advance!
It appears this problem is still not fixed in the GM.I set UIPrerenderedIcon to YES, but the rendered icon includes gloss effect.
Sorry, I confirmed that this problem is solved in the GM. If you would like to erase gross effect, set "Icon already includes gross effect" under "Primary Icons" under "Icon files (iOS 5)" to YES.
