Strange. I filed <rdar://9453805> last year about the docs for that method: ------------- 17-May-2011 02:25 PM Sean McBride: The developer documentation for NSFileManager's createDirectoryAtPath:withIntermediateDirectories:attributes:error: says: Parameters path The path at which to create the new directory. The directory to be created must not yet exist. ... Return Value YES if the operation was successful or already exists, otherwise NO. I believe the sentence "The directory to be created must not yet exist." should be stricken. It conflicts with what's implied by the return value. Also, in practice, passing an existent path works as expected (YES is returned). 09-Mar-2012 02:31 PM Sean McBride: This is fixed in Xcode 4F90's built-in docs. This issue has been verified as resolved and can be closed. ------------- Note that in my experience YES is returned if the directory exists. Do you require 10.7? If so, try the URL version: createDirectoryAtURL:withIntermediateDirectories:attributes:error:. Cheers, -- ____________________________________________________________ Sean McBride, B.
