Ora che hai enumerato le classi e i moduli utilizzati dall'applicazione, potresti aver trovato alcuni nomi di classi e metodi interessanti .
Hook di tutti i metodi di una classe

Copy ios hooking watch class iGoat_Swift.PlistStorageExerciseViewController Hook di un singolo metodo
ios hooking watch method "-[<class_name> <method_name>]" --dump-args --dump-return --dump-backtrace: Hook di un metodo specifico di una classe dumpando i parametri, i backtrace e i ritorni del metodo ogni volta che viene chiamato
Copy ios hooking watch method "-[iGoat_Swift.BinaryCookiesExerciseVC verifyItemPressed]" --dump-args --dump-backtrace --dump-return Cambiare il ritorno booleano
