• Check if NSURL is Local File

  - by golfromeo

  This is a pretty simple question- how can I check if a NSURL is linking to a local file? I know, RTFM, but I checked the documentation and I don't seem to see any methods related to this. The only methods I did find were -isFileReferenceURL and -isFileURL, but I think these only check if the URL directly links to a file. note: I'm making an iPhone app, so by "local file" I mean a .html file stored in the project's resources. Thanks for any help in advance.
