Sometimes when looking at someone else’s large Objective-C program, it is hard to know where to begin.
In such situations, I think it would be helpful to log every call to every non-Apple method.
Is there a way to do that? Basically, make one change in some central place, and log every method that is called. Preferably limited to non-Apple methods.
You can set the environment variable NSObjCMessageLoggingEnabled to YES. This will write a log of all message sends in the folder /tmp/msgSends-xxx.
