When I finally bothered to search for an alternative, and ended up with CCLog, A Variation on NSLog().
CCLog shows much more information, quoting the developer:
My preferred output would be capable of doing this:
- Show on which thread CCLog() was called from.
- Show from which sourcecode file CCLog() was called from.
- Show the linenumber in the sourcecode file CCLog was called from.
I’ve been using it for some time now, and recommend it without reservation!
