Há um problema que o LLDB Import Xia0lldb na Last MacOS Catalina, porque o último LLDB do MacOS usa o Python3. Aqui está uma maneira de mudar para Python2
defaults write com.apple.dt.lldb DefaultPythonVersion 2
Bem -vindo ao xia0lldb - edição python3
Obrigado @lakr por portá -lo para Python3!
Basta abrir o terminal e correr abaixo do comando
git clone https://github.com/4ch12dy/xia0LLDB.git && cd xia0LLDB && ./install.sh
Abaixo está o CMDS, basta usar o alias em cmd.txt
mload [dylib_in_the_iphone_device_path]
Carregue um dylib no processo atual
rr
Mostrar rápido alguns regitores importantes
pwindow
Imprima a chave atual Wincown
xi [code_address]
Basta mostrar o endereço Disassmble +/- 8
DFUC [addr_of_func]
Mostre a função toda desmonte pelo endereço determinado
pclass [oc_object]
Imprima o nome da classe de objeto OC
PBCOPY
Obtenha string do dispositivo de dispositivo iOS
pbPaste [string]
colar string to iOS Pastaboard
Data [object_of_nsdata]
Imprima o objeto nsdata
PCC
É apenas alias do process connect connect://127.0.0.1:1234
WPC
Escreva o registro de PC para controlar o processo exe
Vá para o Env que pode executar o script OC. Este CMD é sempre usado quando o aplicativo Luanch de depuração da backboard, o Debuger apenas atingi.
Imprima todos os adars of OC Object (apenas iOS) e a versão MacOS chegará em breve!

Re importar xia0lldb do lldbinit
A substituição do bt , ele pode restaurar o símbolo OC do quadro no StackFrame. Se você deseja restaurar o símbolo de bloco, pode usar o script IDA Python fornecido para obter o arquivo JSON do símbolo do bloco. Em seguida, entrada sbt -f block_json_file_path no LLDB. Além disso, pode mostrar mais informações: endereço do MEM, endereço do arquivo
// also you can spcail -f block_json_file to restore block symbol
