当我使用Xcode 4构建我的应用程序时,它总是显示以下错误消息:
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"

检查/Volumes/WORK/Works/iMusicBox/Images/list_cell.png pngcrush中的alphas时检测到libpng错误:图像数据不够
但Xcode 3.2没关系 - 为什么？
