问题描述

我有一个/ Documents / Images文件夹,在那个文件夹中有几个名为多年的文件夹,在那些文件夹中我有图像。我要删除图像文件夹中的所有内容(包括文件夹和这些文件夹中的图像)。

I have a /Documents/Images folder , in that folder are several other folders named after years , in those folders i have images. I want to delete everything from the images folder ( including the folders and the images in these folders).

我尝试了几个代码片段,但没有删除文件夹

I tried several code snippets but none delete the folders

我的方法:

- (void) clearCache:(NSString *) folderName{
NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
NSString *documentsDirectoryPath = [paths objectAtIndex:0];
NSFileManager *fm = [NSFileManager defaultManager];
NSString *directory = [documentsDirectoryPath stringByAppendingPathComponent:folderName];
NSLog(@"Removing items at path: %@",directory);
    NSError *error = nil;
BOOL succes = [fm removeItemAtPath:directory error:&error];

/*for (NSString *file in [fm contentsOfDirectoryAtPath:directory error:&error]) {
    //BOOL success = [fm removeItemAtPath:[NSString stringWithFormat:@"%@%@", directory, file] error:&error];
    BOOL success = [fm removeItemAtPath:[directory stringByAppendingPathComponent:file] error:&error];
    if (!success || error) {
        // it failed.
    }
}*/

}

推荐答案

您的代码( [fm removeItemAtPath:directory error:& error]; )应该这样做。如果没有,检查它返回的错误。如果没有错误,但您仍然看到文件/子文件夹 - 提交错误报告!

Your code ([fm removeItemAtPath:directory error:&error];) should do it. If it doesn't, inspect the error it returns. If there's no error, but you still see files/subfolders - file a bug report!
