iOS 是静态框架还是动态框架？
iOS is it a static or a dynamic framework?
这听起来像是一个愚蠢的问题，但是如果您有一个 thirdParty.framework 文件，您能分辨出它是静态的还是动态的吗？我的意思是，如果你往里面看，它们看起来有什么不同吗？
两者皆可。
但是，只有 iOS8+ 允许在应用程序包中使用动态框架。
找出方法是查看 .framework 并在主文件上使用 file 命令：
$ cd iOS/Crashlytics.framework
$ ls -l
total 9984
-rwxr-xr-x 1 andy staff 4710656 11 Sep 17:11 Crashlytics
drwxr-xr-x 8 andy staff 272 11 Sep 17:11 Headers
-rw-r--r-- 1 andy staff 1553 11 Sep 17:11 Info.plist
drwxr-xr-x 3 andy staff 102 11 Sep 17:11 Modules

$ file Crashlytics
Crashlytics: Mach-O universal binary with 5 architectures
Crashlytics (for architecture armv7): current ar archive random library
Crashlytics (for architecture armv7s): current ar archive random library
Crashlytics (for architecture i386): current ar archive random library
Crashlytics (for architecture x86_64): current ar archive random library
Crashlytics (for architecture arm64): current ar archive random library
其中 ar archive 表示 "static library"。
或者，"dynamic" 框架将如下所示，并明确声明它是动态链接的。
