今天引入了几个png的图片。发现如下错误!
While reading /XXX/XXX/XXX/img1.png pngcrush caught libpng error: Not a PNG filCould not find file: /Users/XXX/Library/Developer/Xcode/DerivedData/CookBookDemo-cnttcobrbmvbddeiesgsxnfwihfe/Build/Products/Debug-iphoneos/CookBookDemo.app/img1.pngCommand /Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/usr/bin/copypng emitted errors but did not return a nonzero exit code to indicate failure
原因,就是引入的png图片,图片内部编码不符合真正的png格式。(很可能就是jpg图片修改了一下后缀名)。
解决方法也很简单了,就是用正宗png。
