iphone - NSDirectoryEnumerator 和子文件夹

Question

我有一个 iPhone 应用程序，可以搜索文件夹、整理所有音频文件的数组，然后播放它们。问题是，如果我正在搜索的文件夹中有子文件夹，它只会跳过它/不进入其内容。

我的代码如下:

 NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
 NSString *documentsDirectory = [paths objectAtIndex:0];
 NSDirectoryEnumerator *direnum = [[NSFileManager defaultManager] enumeratorAtPath:documentsDirectory];

 NSString *pname;

 while (pname = [direnum nextObject])
{
      [musicArray addObject:[pname stringByDeletingPathExtension]];
}

我想做的是继续搜索其子文件夹，我该怎么做？

Answer 1

它会自动执行。 From the documentation :

An enumeration is recursive, including the files of all subdirectories, and crosses device boundaries. An enumeration does not resolve symbolic links, or attempt to traverse symbolic links that point to directories.
