Question

I don’t like using Xcode’s console output window when debugging an iPhone app in the Simulator (or on a device for that matter). I’d like to be able to use the Unix toolbox and do things like filter the logging output with grep. But to do this I need to get Xcode to send the logging output for the running iPhone app to the Terminal.

Is there any way to accomplish this?

Couldn’t say how it’d work in the simulator, but redirecting stdout is not terribly difficult. Say you wanted to pipe it into your own view:

#include <unistd.h>

stderr->_write = RedirectOutputToView;
stdout->_write = RedirectOutputToView;

And use the prototype:

int RedirectOutputToView(void *inFD, const char *buffer, int size);
