我目前正在使用nm -ufm来获取库文件中的导入列表。但是，对于objective-c符号，我似乎只是获取导入的类定义。例如，libGoogleAdMobAds.a中导入的符号的一部分是：
libGoogleAdMobAds.a(GADIdentifierUtilities.o) (for architecture i386):

其中列出了一堆Objective-c类，但我想确切地知道调用哪些方法。
我对Objective-c方法调用的实现细节知之甚少（原谅我，我的意思是“消息传递”），但是因为我也看到导入的_objc_msgSend，这是否意味着调用使用某种反射在运行时通过名称解析？
无论如何，是否可以获得库使用的实际方法列表？
注意：应该可以，因为Apple可以。我正在调查我对使用uniqueIdentifier UIDevice方法的iOS应用程序的拒绝，但按照建议的here做一个简单的grep太过模糊了，字符串可以是任何东西，包括文件中的字符串资源，我想证实我使用grep获得的信息和更实质的报告，例如来自nm的报告。
