@mikeabdullah Q: If NSBundle pathForResource deprecates, how'd you get the path to a file in the bundle? fileURLWithPath relative path?
Mike Abdullah ‏@mikeabdullah 12 Apr 2013

@benclayton -[NSURL path]. In theory we shouldn't ever have to deal with paths for local files these days, though!
Cédric Luthi ‏@0xced 12 Apr 2013

@mikeabdullah @benclayton In theory! -fileExistsAtPath: -isReadableFileAtPath: and co don’t have xxxAtURL: equivalent. :-(
Mike Abdullah ‏@mikeabdullah 12 Apr 2013

@0xced @benclayton yes they do -checkResourceIsReachableAndReturnError: NSURLIsReadableKey
Michael Tsai ‏@mjtsai 12 Apr 2013

@mikeabdullah @0xced @benclayton I tried those a while ago and found them much slower than the path variants.
Mike Abdullah ‏@mikeabdullah 12 Apr 2013

@mjtsai @0xced @benclayton that's interesting to know. Ideally, code should avoid doing that sort of check, mind!
Michael Tsai ‏@mjtsai 12 Apr 2013

@mikeabdullah @0xced @benclayton Also note that NSURLIsReadableKey and the other keys could give you a stale value due to the cache.
Mike Abdullah ‏@mikeabdullah 12 Apr 2013

@mjtsai @0xced @benclayton clear the cache first then?
Michael Tsai ‏@mjtsai 12 Apr 2013

@mikeabdullah @0xced @benclayton You could, but I don’t really see the advantage compared with the path methods or stat().
Mike Abdullah ‏@mikeabdullah 12 Apr 2013

@mjtsai @0xced @benclayton in theory (I haven't tried it) it can give your users an idea of *why* the file's not accessible. That's about it

@mikeabdullah Anyway, I would standardize all calls to a category on NSURL. Then you can change the implementation as best practices change.
