I have audio class that sample the buffer and with NSNotification it calls another class and send a data(int).

I get this warning that runs many many times a second:

class __NSCFNumber autoreleased with no pool in place - just leaking - break on objc_autoreleaseNoPool()

class __NSCFString autoreleased with no pool in place - just leaking - break on objc_autoreleaseNoPool() to debug

what does it means?
yes I have NSNumber in that class and NSString.
they are not allocated.

do I need another thread?
what’s wrong?

    It means that, for whatever thread that code is running on, no autorelease pool has been set up before that code runs. For AppKit- or UIKit-based apps, the framework normally managed one for you on the main thread, but you’ll still need to create them yourself if you’re using other threads. For apps that are not based on AppKit or UIKit, you’ll pretty much always need to make sure there’s an autorelease pool around when you’re running Objective-C code.
