iOS如何区分framework是静态库还是动态库

众所周知，framework是可以做动态库也可以做静态库的，那么我们手头上有个framework，如何区分它的类型呢？

方法：命令行进入动态库文件，使用file命令查看输出内容可以看到区别。以静态库文件-MAMapKit.framework与动态库文件-AFNetworking.framework为例。

1. 静态库文件-MAMapKit.framework

cd /Users/***/Desktop/Framework/MAMapKit.framework
file MAMapKit

输出

MAMapKit: Mach-O universal binary with 4 architectures: [arm_v7:current ar archive random library] [arm64]
MAMapKit (for architecture armv7):  current ar archive random library
MAMapKit (for architecture i386):   current ar archive random library
MAMapKit (for architecture x86_64): current ar archive random library
MAMapKit (for architecture arm64):  current ar archive random library

archive表明这是一个静态库

2. 动态库文件-AFNetworking.framework

cd /Users/***/Desktop/Framework/AFNetworking.framework
file AFNetworking

输出

AFNetworking: Mach-O universal binary with 2 architectures: [arm_v7:Mach-O dynamically linked shared library arm_v7] [arm64:Mach-O 64-bit dynamically linked shared library arm64]
AFNetworking (for architecture armv7):  Mach-O dynamically linked shared library arm_v7
AFNetworking (for architecture arm64):  Mach-O 64-bit dynamically linked shared library arm64

dynamically linked shared library表明这是一个动态库
