Convert NSURL to local file path

I have an NSURL that looks like this:

file://localhost/Users/myuse开发者_Go百科r/myfile.txt

Is there a standard function to convert it to a local file path looking like this:

/Users/myuser/myfile.txt

Use the -[NSURL path] method:

NSLog(@"%@", myUrl.path);

From the documentation:

The path of the URL, unescaped with the stringByReplacingPercentEscapesUsingEncoding: method. If the receiver does not conform to RFC 1808, returns nil.

If this URL object contains a file URL (as determined with isFileURL), the return value of this method is suitable for input into methods of NSFileManager or NSPathUtilities. If the path has a trailing slash it is stripped.

Per RFC 3986, the leading slash after the authority (host name and port) portion is treated as part of the path.

Note that you can create such a URL with +[NSURL fileURLWithPath:].

Swift 4:

absoluteURL.path 

or

yourUrl.path
