如何查看库信息与合并库

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/DemoFramework
10 Architectures in the fat file: /Users/***/Desktop/Release/DemoFramework are: i386 x86_64 armv7 arm64 

3.注意：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；最后找到newpath下生成的库替换之前的库文件就行。
