Existe el problema de que LLDB importe Xia0lLDB en los últimos macOS Catalina, porque el LLDB LLDB de los últimos macOS usa Python3. Aquí hay una forma de cambiarlo a Python2
defaults write com.apple.dt.lldb DefaultPythonVersion 2
Bienvenido a XIA0LLDB - Edición Python3
¡Muchas gracias @lakr por portarlo a Python3!
Simplemente abra terminal y ejecute el comando a continuación
git clone https://github.com/4ch12dy/xia0LLDB.git && cd xia0LLDB && ./install.sh
A continuación se muestra CMD, solo use alias en cmd.txt
mLoad [dylib_in_the_iphone_device_path]
Cargar un dylib en el proceso de corriente
RR
Avanzar a algunos regisores importantes
pwindow
Llave de corriente de impresión windown
xi [code_address]
solo muestre la dirección desassmble +/- 8
DFUC [ADDR_OF_FUNC]

RE Import XIA0LLDB de LLDBINIT
El reemplazo de bt , puede restaurar el símbolo OC de marco en StackFrame. Si desea restaurar el símbolo de bloque, puede usar el script Ida Python proporcionado para obtener el archivo JSON del símbolo de bloque. Luego ingrese sbt -f block_json_file_path en LLDB. Además de él, puede mostrar más información: dirección MEM, dirección de archivo
// also you can spcail -f block_json_file to restore block symbol
