Ahora que has enumerado las clases y módulos utilizados por la aplicación, es posible que hayas encontrado algunos nombres de clase y método interesantes .
Enganchar todos los métodos de una clase
ios hooking watch class <class_name>: Engancha todos los métodos de una clase, volcando todos los parámetros iniciales y retornos
Copiar ios hooking watch class iGoat_Swift.PlistStorageExerciseViewController Enganchar un solo método
ios hooking watch method "-[<class_name> <method_name>]" --dump-args --dump-return --dump-backtrace: Engancha un método específico de una clase volcando los parámetros, backtraces y retornos del método cada vez que se llama
Copiar ios hooking watch method "-[iGoat_Swift.BinaryCookiesExerciseVC verifyItemPressed]" --dump-args --dump-backtrace --dump-return Cambiar el retorno booleano
