ios - NSFileManager 如何返回文件路径的文件夹名称

Question

我有这条路:

/Users/mac/Library/Application Support/iPhone Simulator/7.0.3/Applications/5C6B84DE-2F18-48A8-AC4D-5C4973F19050/tmp/Root/Folder 1/test.pdf

我想提取 /Users/mac/Library/Application Support/iPhone Simulator/7.0.3/Applications/5C6B84DE-2F18-48A8-AC4D-5C4973F19050/tmp/Root/Folder 1/从这个路径。

我可以使用 NSFileManager 获取包含 test.pdf 文件的目录路径，还是我需要自己解析它。

您可以使用 NSString 的 stringByDeletingLastPathComponent 来完成此操作类:

NSString *path = @"/Users/mac/Library/Application Support/iPhone Simulator/7.0.3/Applications/5C6B84DE-2F18-48A8-AC4D-5C4973F19050/tmp/Root/Folder 1/test.pdf";

NSString *folder = [path stringByDeletingLastPathComponent];

Reference :

stringByDeletingLastPathComponent

Returns a new string made by deleting the last path component from the receiver, along with any final path separator.

- (NSString *)stringByDeletingLastPathComponent

Return Value

A new string made by deleting the last path component from the receiver, along with any final path separator. If the receiver represents the root path it is returned unaltered. Discussion

Note that this method only works with file paths (not, for example, string representations of URLs).
