Can't save file to disk, no clue why

Question

I'm trying to write a string to disk:

return [fileContent writeToFile:path atomically:YES encoding:NSUnicodeStringEncoding error:error];

But it always fails with the following error:

Error Domain=NSCocoaErrorDomain Code=4 "The folder “ddd.csv” doesn’t exist." UserInfo=0xc4a08b0 {NSUnderlyingError=0xc49ba60 "The operation couldn’t be completed. No such file or directory", NSFilePath=file://<path to file>, NSUserStringVariant=Folder}

The path to the file seems to be valid (I've obscured it here) and the string (NSMutableString) is definitely not 0 length. This code used to work before Mountain Lion. Can anyone help shed a light on what could be going on?

Edit: The value of path is: file://localhost/Users/cocoaster/Downloads/ddd.csv

Answer 1

Since you're using a save panel the result comes back as a URL, so if you need a path, convert the result to a path with the path command: [url path].

Alternately, you can use writeToURL:atomically: if that version is available for whatever class fileContent is.
