Performance is another reason. IIRC, in earlier OS X releases it turned out that there was significant overhead stemming from converting between different types of file references as a call went up and down the stack — NSString/CFString <—>NSURL/CFURL <—> FSRef <—> C strings, etc. (This may sound trivial, but it's the kind of trivial thing that can eat up CPU time inside loops or performance-critical code.) So there's been some effort to standardize on NSURL/CFURL, at least above the POSIX/kernel layer.
So I don't have numbers to back this up, but my understanding is that NSURL-based APIs will be slightly faster than NSString-based ones. Though probably not enough faster to worry about unless your code is performance-sensitive. —Jens _______________________________________________ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.
