objective-c - 将 NSURL 转换为本地文件路径

Question

我有一个如下所示的 NSURL:

file://localhost/Users/myuser/myfile.txt

是否有标准函数可以将其转换为如下所示的本地文件路径:

/Users/myuser/myfile.txt

Answer 1

使用-[NSURL路径]方法:

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

来自文档:

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.

请注意，您可以使用 +[NSURL fileURLWithPath:] 创建这样的 URL。
