Using const strings


  • Subject: Using const strings
  • From: Darrin Cardani <email@hidden>

I'm working in Objective-C++, and it occurs to me that something I'm doing might not be a good idea. :-) I've done a few things like this in a header:

const CFStringRef someString = CFSTR ("blah");

Then later I do something like this:

NSArray* anArray = [ NSArray arrayWithObjects:(NSString*)someString, nil ];

or

NSDictionary* aDict = [ NSDictionary dictionaryWithObject:(NSString*)someString
andKey:someOtherString ];

Is this going to cause any problems when I release the array or dictionary? Can a const CFString have a retain count? Or is it marked in some special way that calling release doesn't do anything to it?

Thanks,
Darrin
