如何在我的iPhone应用程序的documents目录内创建目录?

问题描述:

我想将文件存储在documents目录内的特定目录中,这样我就可以遍历所有这些文件并显示给用户选择。

I would like to store files in a specific directory inside the documents directory, so that I can iterate over all these files and show them to the user for selection. Is that possible?

是的,您可以这样做:

NSString *rootString = [NSSearchPathForDirectoriesInDomains(NSDocumentDirectory,NSUserDomainMask,YES) objectAtIndex:0];
    self.root = [rootString stringByAppendingPathComponent:@"DirectoryName"];

    NSFileManager *fileManager = [NSFileManager defaultManager];
    if ([fileManager fileExistsAtPath:root isDirectory:YES] == NO)
    {
        [fileManager createDirectoryAtPath:root attributes:nil];
    }

对于检索,您可以执行以下操作:

And For retrieving you can do this:

NSError *error;

NSArray *files = [fileManager contentsOfDirectoryAtPath:root error:&error];

希望这会有所帮助,
