Objective-C：从路径字符串中提取文件名 [英] Objective-C: Extract filename from path string

问题描述

当我有 NSString 和 /Users/user/Projects/thefile.ext 我想提取<$

When I have NSString with /Users/user/Projects/thefile.ext I want to extract thefile with Objective-C methods.

这是最简单的方法是什么？

What is the easiest way to do that?

推荐答案

取自 NSString参考，可以使用：

NSString *theFileName = [[string lastPathComponent] stringByDeletingPathExtension];

lastPathComponent 调用将返回 thefile.ext ， stringByDeletingPathExtension 将从末尾删除扩展名。

The lastPathComponent call will return thefile.ext, and the stringByDeletingPathExtension will remove the extension suffic from the end.
