命令行进入动态库文件，使用file命令可以看到区别，分别以腾讯分享framwork(静态)和阿里直播framwork（动态）为例展示:
cd TencentOpenAPI.framework
file TencentOpenAPI
输出
TencentOpenAPI: Mach-O universal binary with 4 architectures: [arm_v7:current ar archive] [arm64]
TencentOpenAPI (for architecture armv7): current ar archive
TencentOpenAPI (for architecture i386): current ar archive
TencentOpenAPI (for architecture x86_64): current ar archive
TencentOpenAPI (for architecture arm64): current ar archive
archive表明这是一个静态库
cd AliyunPlayerSDK.framework
file AliyunPlayerSDK
输出
AliyunPlayerSDK: Mach-O universal binary with 4 architectures: [i386:Mach-O dynamically linked shared library i386] [arm64]
AliyunPlayerSDK (for architecture i386): Mach-O dynamically linked shared library i386
AliyunPlayerSDK (for architecture x86_64): Mach-O 64-bit dynamically linked shared library x86_64
AliyunPlayerSDK (for architecture armv7): Mach-O dynamically linked shared library arm_v7
AliyunPlayerSDK (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
