-------------------------------------------------------------------------------- /README.md: -------------------------------------------------------------------------------- 1 | # SwiftVTHook（beta） 2 | 3 | ## 介绍 4 | SwiftVTHook 是一种基于Swift的虚函数表的函数hook 方案，目前已经形成demo。不包括Swift msg_send以及静态地址直接调用的方式进行函数调用。 5 | 6 | ## 进展 7 | 目前SwiftVTHook处于理论实验阶段，编译器对Swift的优化影响、泛型、Type结构等还需要进一步完善。 8 | 9 | ## demo 10 | demo 只支持真机arm64架构。建议release模式下进行编译运行。由于相对对OC比较熟悉，因此核心代码采用OC编写。 11 | 12 | ## 风险 13 | 在修改编译选项时，代码可能存在优化，跳表方式的函数调用转为静态地址调用，因此可能失效。 14 | 另外， 15 | demo中可能存在的问题通过 #warning 的方式做了介绍 16 |
