Find out where NSLogs are coming from?

In my app I am receiving 3 NSLogs below:

AudioStreamBasicDescription:  2 ch,  44100 Hz, 'lpcm' (0x00000C2C) 8.24-bit little-endian signed integer, deinterleaved
2012-06-01 17:05:43.397 App[1579:707] authenticateWithCompletionHandler: enter
2012-06-01 17:05:43.399 App[1579:707] authenticateWithCompletionHandler: exit

However, I do not know where these NSLogs are coming from. Is there any way to find out without going through every single class in my project?

These logs are really bugging me and makes it more difficult to actual see real console output.

Any advice would be appreciated!

Thanks!

Solution

Yes, in Xcode go to the little search bar on left (See the picture), and search for the right keywords.

Note: I'm guessing you imported some Game Center stuff to your project, that's where they're probably coming from
