ios - 如何获取 NSDocumentDirectory 中的目录列表？

Question

我在 NSDocumentDirectory 中创建了一些目录作为

if (![tbxCreateFolder.text isEqualToString:@""]) {
NSArray  *arrPaths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
NSString *documentsDirectoryStr = [arrPaths objectAtIndex:0]; // Get documents folder
NSString *dataPath = [documentsDirectoryStr stringByAppendingPathComponent:[NSString stringWithFormat:@"/%@",tbxCreateFolder.text]];

if (![[NSFileManager defaultManager] fileExistsAtPath:dataPath]){

    NSError* error;
    if([[NSFileManager defaultManager] createDirectoryAtPath:dataPath withIntermediateDirectories:NO attributes:nil error:&error]){

        NSLog(@"success");
        //Perfrom DB Insertation
    }
    else
    {
        NSLog(@"[%@] ERROR: attempting to write create MyFolder directory", [self class]);
        NSAssert( FALSE, @"Failed to create directory maybe out of disk space?");
    }
}

现在我想获取我在文档文件夹中创建的目录列表，但响应是

NSArray *arrPaths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
NSString *basePathString = ([arrPaths count] > 0) ? [arrPaths objectAtIndex:0] : nil;
NSLog(@"dirContents %@",basePathString);

响应是:

代码如下:

NSString *documentDirPath = [NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES) objectAtIndex:0];
// create directory named "test"
[[NSFileManager defaultManager] createDirectoryAtPath:[documentDirPath stringByAppendingPathComponent:@"test"] withIntermediateDirectories:YES attributes:nil error:nil];
// retrieved all directories
NSLog(@"%@", [[NSFileManager defaultManager] contentsOfDirectoryAtPath:documentDirPath error:nil]);

 NSArray *paths = [[NSFileManager defaultManager] contentsOfDirectoryAtPath:documentDirPath error:nil];
 BOOL isDir = NO;
 for (NSString *path in paths) {
     if ([fileManager fileExistsAtPath:path isDirectory:&isDir] && isDir) {
         // path is directory
     }
}
