NSItemReplacementDirectory isn’t what you want either; that’s supposed to be used for implementing a safe save feature, IIRC.
Probably your best bet is [NSURL fileURLWithPath:NSTemporaryDirectory()]. It’s not ideal, but I think it’s the best we’ve got at the moment. I actually still use the FSFindFolder() API and then use CFURLCreateFromFSRef() to get a URL, but that’s looking less and less like a good solution these days. I actually filed a radar report on this last week (rdar://11142974); there are actually quite a lot of directories that are not available via -URLForDirectory:inDomain:bla:bla:bla: that were available via the older FSFindFolder() API, many of which were quite useful. A few of them are:
And a whole lot more. Feel free to file a radar report yourself if you agree that -URLForDirectory:etc:etc:etc:etc: needs to be beefed up; Apple uses duplicate radar reports to prioritize fixes.
