NSString memory management question

Subject: NSString memory management question
From: Rick Mann <email@hidden>
Date: Tue, 22 Apr 2008 15:25:35 -0700

I wrote a routine that creates a CFStringRef from some USB calls. I use it like this:

	NSString* s = (NSString*) createStringDescriptor(dev, stringIndex);
	[mSerialNumberDisplay setStringValue: [s lowercaseString]];
	[s release];

Two main questions: am I right to release the bridged NSString* s? and, what happens in -lowercaseString? How does that get released?

TIA,
--
Rick
