unhook methods needed

[dodikk]

While writing unit tests, I want to set up a hook, run a test and return the system to the previous step. Current implementation with

+ (void)hookInstanceMethodForClass:(Class)targetClass
                      withSelector:(SEL)targetSelector
           prototypeMethodSelector:(SEL)prototypeSelector
                hookMethodSelector:(SEL)hookSelector;

does not work.

See my implementation attempts in : aa06a2e
