如何静态转储在Cocoa应用程序中调用的所有ObjC方法？ [英] How to statically dump all ObjC methods called in a Cocoa App?

问题描述

假设我有一个基于Cocoa的Mac或iOS应用程序。我想在我的应用程序的源代码 或上运行一个静态分析器来检索所有Objective-C方法的列表 strong>称为。是否有可以执行此操作的工具？

以下几点：

1. 我在寻找一个静态解决方案。我不是在寻找动态解决方案。




2. 可以对二进制或源代码运行的任何东西都是可以接受的。




3. 理想情况下，输出只是一个重复的Objective-C方法列表，如：

    
    ... 
     -  [MyClass foo] 
    ... 
    + [NSMutableString stringWithCapacity：] 
    ... 
     -  [NSString length] 
    ... 
     
   （如果它不是去重的，那么很酷）

4. 我熟悉 class-dump ，但AFAIK会将二进制文件中声明的类转储，而不是二进制文件中的方法。这不是我想要的。如果我错了，您可以使用类别转储执行此操作，请更正我。




5. 这是可行的。所以如果不是，这也是一个很好的答案。 ：）

解决方案

我最清楚的是 otx ，它是 otool 的一个包装，可以在objc_msgSend（）调用站点重建选择器。

Assume I have a Cocoa-based Mac or iOS app. I'd like to run a static analyzer on my app's source code or my app's binary to retrieve a list of all Objective-C methods called therein. Is there a tool that can do this?

A few points:

1. I am looking for a static solution. I am not looking for a dynamic solution.

2. Something which can be run against either a binary or source code is acceptable.

3. Ideally the output would just be a massive de-duped list of Objective-C methods like:

   …
   -[MyClass foo]
   …
   +[NSMutableString stringWithCapacity:]
   …
   -[NSString length]
   …
   

   (If it's not de-duped that's cool)

4. If other types of symbols (C functions, static vars, etc) are present, that is fine.

5. I'm familiar with class-dump, but AFAIK, it dumps the declared Classes in your binary, not the called methods in your binary. That's not what I'm looking for. If I am wrong, and you can do this with class-dump, please correct me.

6. I'm not entirely sure this is feasible. So if it's not, that's a good answer too. :)

解决方案

The closest I'm aware of is otx, which is a wrapper around otool and can reconstruct the selectors at objc_msgSend() call sites.
