Answer 1

I think this is within Apple's lib, it seems that there is no direct way of switching it off - I would submit a "bug" ticket ...

I'm pretty sure, that it is not possible to overload/overwrite the NSLog method in order to avoid those logs.

May I ask whether there is a specific need for switching this off?
