Decompile objective-c using the Class-dump tool

Class-dump is an easy-to-use objective-c anti-compile analysis tool that extracts class definitions from objective-c compiled binaries in the form of objective-c header files.

Class-dump is an open source tool, the official website address is: http://stevenygard.com/projects/class-dump/

the use parameters are :

Examples of use:
Add the Class-dump tool in the current directory, the file to be analyzed is Myapp.app, and in the current directory, to place the exported header file in the Exportheader directory under the current directory, the command is
./class-dump-h Myapp.app-o./exportheader
