TODO

• add more arg: -b=--enable-restore-objc-symbol, while pass in: "--symbol-list=WhatsApp=" or "--symbol-list=Frameworks/SharedModules.framework/SharedModules=" for no json symbol file
• after shell run IDA export symbol, add to here, then all step can automate do it
• uninstall app in iPhone, then reinstall new ipa to iPhone
