I have an NSFilePresenter which is watching a directory. When I get notice there's a new file I (on a queue) perform a coordinated read on it using NSFileCoordinator. The read block only gets called after the file has been completely written. Yes I get multiple callbacks on the file presenter as the file grows, but it doesn't matter, it's very easy to figure out I'm waiting for the coordinated read to occur and throw them away. I have no idea what the apple sample DirectoryWatcher uses, I rolled my own, but I'm guessing it uses file coordination. I'm getting much in the habit now of thinking, every single time I do any kind of file operation, whether I should use file coordination on it. _______________________________________________ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.
