【越狱-逆向】基于Cycript实现的一些实用函数
A Cycript utility library for iOS reverse engineering and jailbreak research. It wraps common runtime introspection tasks — finding the frontmost view controller, listing methods on a class with regex filtering — into convenient functions you import into a live Cycript session over SSH. Aimed at developers doing iOS app analysis on jailbroken devices.
The method-listing function with regex support is genuinely useful — grepping Objective-C runtime methods interactively saves a lot of time during analysis. Single-file library means zero setup friction beyond copying one file. The frontmost view controller helper is a staple that everyone reimplements; having it ready is practical. 730 stars suggests it resonated with the iOS reverse engineering community during its active window.
Dead since June 2018 — Cycript itself is effectively abandoned, its author stopped maintaining it, and it does not work on modern iOS versions (post-12 support is spotty at best). No documentation beyond screenshots in a README, all in Chinese with no English translation. The entire value proposition depends on a jailbroken device and a working Cycript installation, which is increasingly difficult to achieve. Frida has largely replaced this workflow with active maintenance and broader platform support.
