iOS是静态还是动态框架？ [英] iOS is it a static or a dynamic framework?

问题描述

这可能听起来像一个愚蠢的问题但是如果你有一个thirdParty.framework文件，你能告诉它是静态的还是动态的？我的意思是，如果你看里面它们看起来有什么不同吗？

This might sound like a silly question but If you have a thirdParty.framework file, can you tell if it's static or dynamic? I mean, do they look different if you look inside?

推荐答案

它可以是。

但是，只有iOS8 +才允许应用程序包中的动态框架。

Only iOS8+ will allow dynamic frameworks in the app bundle, however.

查找方法是查看 .framework 并在主文件上使用文件命令：

The way to find out is to look in the .framework and use the file command on the main file:

$ 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

其中 ar archive 表示静态库。

或者，动态框架将如下所示，并明确声明它是动态链接的。

Alternatively, a "dynamic" framework will look like this and explicitly state that it's dynamically linked.

$ cd /Library/Frameworks/iTunesLibrary.framework/
$ ls -l
total 40
