Uygulamamı Xcode 4 ile oluşturduğumda her zaman şu hata mesajını gösteriyor:
CopyPNGFile /Users/michaelchen/Library/Developer/Xcode/DerivedData/iMusicBox-boeawugacmhacbdtyymnprzfobyq/ArchiveIntermediates/iMusicBox/InstallationBuildProductsLocation/Applications/iMusicBox.app/list_cell.png Images/list_cell.png
cd /Volumes/WORK/Works/iMusicBox
setenv PATH "/Developer/Platforms/iPhoneOS.platform/Developer/usr/bin:/Developer/usr/bin:/usr/bin:/bin:/usr/sbin:/sbin"

/Volumes/WORK/Works/iMusicBox/Images/list_cell.png içindeki alfaları kontrol ederken pngcrush libpng hatasını yakaladı: Yeterli resim verisi yok
ama Xcode 3.2 ile sorun yok - neden?
