Objective-C Workflow

This is the Objective-C plugin that ships with Binary Ninja. It provides additional support for analyzing Objective-C binaries.

Some of the main features offered by this plugin are:

• Function Call Cleanup. When using the Objective-C workflow, calls to objc_msgSend can be replaced with direct calls to the relevant function's implementation.

• Name and Type Recovery. Using runtime information embedded in the binary, Binary Ninja can automatically apply names and type information to Objective-C functions.

• Structure Markup. Data variables are automatically created for Objective-C structures such as classes and method lists to enable easy navigation.

• Data Renderers. Formatting of Objective-C types such as tagged and/or (image-)relative pointers is improved via custom data renderers.

• CFString Handling. Data variables are automatically created for all CFString instances present in the binary.

For more details and usage instructions, see the user guide.

Building

This plugin can be built and installed separately from Binary Ninja via the following commands:

git clone https://github.com/Vector35/workflow_objc.git && cd workflow_objc
git submodule update --init --recursive
cmake -S . -B build -GNinja
cmake --build build -t install
