如何删除Documents目录的内容（而不是Documents目录本身）？ [英] How to delete the contents of the Documents directory (and not the Documents directory itself)?

问题描述

我想删除Documents目录中包含的所有文件和目录。

I want to delete all the files and directories contained in the Documents directory.

我相信使用 [fileManager removeItemAtPath：documentsDirectoryPath error：nil] 方法也会删除文档目录。

I believe using [fileManager removeItemAtPath:documentsDirectoryPath error:nil] method would remove the documents directory as well.

是否有任何方法可以删除目录中的内容并将空目录留在那里？

Is there any method that lets you delete the contents of a directory only and leaving the empty directory there?

推荐答案

试试这个：

NSString *folderPath = [NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES) objectAtIndex:0]; 
NSError *error = nil;
for (NSString *file in [[NSFileManager defaultManager] contentsOfDirectoryAtPath:folderPath error:&error]) {
    [[NSFileManager defaultManager] removeItemAtPath:[folderPath stringByAppendingPathComponent:file] error:&error];
}
