查看静态库文件支持的指令集架构的方法

例如现在查看libogg.a支持的指令集

以管理员的身份在终端下进入libogg.a库文件所在目录，执行lipo -info ibogg.a如下

localhost:~ developer$ cd desktop

localhost:desktop developer$ cd SpeexRecord

localhost:SpeexRecord developer$ lipo -info libogg.a

Architectures in the fat file: libogg.a are: i386 armv6 armv7

// 结果 liboog.a支持的指令集架构为 inter 32位 armv6 32位 armv7 32位

还有一种方法

以管理员的身份在终端下，执行file libidn.a所在的路径如下MobbyDevelopers-MacBook-Pro:~ developer$ file /Users/developer/Desktop/XMPP/Vendor/libidn/libidn.a

/Users/developer/Desktop/XMPP/Vendor/libidn/libidn.a: Mach-O universal binary with 5 architectures

/Users/developer/Desktop/XMPP/Vendor/libidn/libidn.a (for architecture x86_64):current ar archive random library

/Users/developer/Desktop/XMPP/Vendor/libidn/libidn.a (for architecture armv7):current ar archive random library

/Users/developer/Desktop/XMPP/Vendor/libidn/libidn.a (for architecture armv7s):current ar archive random library

/Users/developer/Desktop/XMPP/Vendor/libidn/libidn.a (for architecture arm64):current ar archive random library

/Users/developer/Desktop/XMPP/Vendor/libidn/libidn.a (for architecture i386):current ar archive random library
