1.打开终端，执行如下命令：

　　$ lipo -info path

　　$ lipo -create path path -output newpath

2.示例：

1 $ lipo -info /Users/***/Desktop/Release-iphoneos/DemoFramework.framework/DemoFramework 2 Architectures in the fat file: /Users/***/Desktop/Release-iphoneos/DemoFramework.framework/DemoFramework are: armv7 arm64 3  4 $ lipo -info /Users/***/Desktop/Release-iphonesimulator/DemoFramework.framework/DemoFramework 5 Architectures in the fat file: /Users/***/Desktop/Release-iphonesimulator/DemoFramework.framework/DemoFramework are: i386 x86_64 6  7 $ lipo -create /Users/***/Desktop/Release-iphoneos/DemoFramework.framework/DemoFramework /Users/***/Desktop/Release-iphonesimulator/DemoFramework.framework/DemoFramework -output /Users/***/Desktop/Release/DemoFramework 8  9 $ lipo -info /Users/***/Desktop/Release/DemoFramework10 Architectures in the fat file: /Users/***/Desktop/Release/DemoFramework are: i386 x86_64 armv7 arm64 

3.注意：

　　a) path可以通过把文件拖入终端中获得；

　　b) 如果是.a文件，path就是.a的路径；如果是.framework，path是framework里面的那个路径；

　　c) 最后找到newpath下生成的库替换之前的库文件就行。
