这可能听起来像一个愚蠢的问题，但如果您有第三方 Party.framework 文件，您能判断它是静态还是动态吗？我的意思是，如果你往里面看，它们看起来有什么不同吗？
两者都可以。
然而，只有 iOS8+ 才允许应用程序包中使用动态框架。
找出答案的方法是查看.framework并使用file主文件上的命令：
$ 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
-rwxr-xr-x 1 andy staff 146164 11 Sep 17:11 run
-rwxr-xr-x 1 andy staff 241688 11 Sep 17:11 submit
$ 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
Where ar archive意思是“静态库”。
或者，“动态”框架将如下所示并明确声明它是动态链接的。
