I want to decompile a .a objective-c iOS library. I search to Google and the site and find a few post. Most useful one was below post:
https://stackoverflow.com/a/2336679/1939409
According to the post, I use below command in my mac os terminal:
otool -tV mylibrary.a
It is working. Actually it prints the codes of .o files in my terminal. Part of the printed text is:
Archive : mylibrary.a (architecture armv7)
mylibrary.a(LIConnection.o) (architecture armv7):

Now the question is that, is there any tools for convert above codes (I do not know, what is the language of the code) to a high level .m files with objective-c language?
