使用Xcode 4构建应用-它始终显示有关PNG图像的错误
当我使用Xcode 4构建应用程序时,它始终显示以下错误消息: 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" "/Developer/Platforms/iPhoneOS.platform/Developer/Library/Xcode/PrivatePlugIns/iPhoneOS Build System Support.xcplugin/Contents/Resources/copypng" -compress "" /Volumes/WORK/Works/iMusicBox/Images/list_cell.png /Users/michaelchen/Library/Developer/Xcode/DerivedData/iMusicBox-boeawugacmhacbdtyymnprzfobyq/ArchiveIntermediates/iMusicBox/InstallationBuildProductsLocation/Applications/iMusicBox.app/list_cell.png 在/Volumes/WORK/Works/iMusicBox/Images/list_cell.png pngcrush中检查alpha时发现libpng错误:图像数据不足 但是Xcode 3.2可以-为什么?
