如何隐藏在ios中的文档目录中创建的文件夹？ [英] How to hide folders created in Document Directory in ios?

问题描述

我已经以编程方式创建了一些PDF文件，我使用以下代码将其存储到设备内存中>>>>

I have created some PDF files programatically, which i am storing into the devices memory using the following code >>>>

    NSString *fileName = [NSString stringWithFormat:@"SampleTextFile.pdf",strFinalString];

    NSArray *path = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
    NSString *saveDirectory = [path objectAtIndex:0];
    NSString *saveFileName = fileName;
    NSString *documentPath = [saveDirectory stringByAppendingPathComponent:saveFileName];

我可以在Devices Document文件夹中看到该文件。

I can see the file in the Devices Document folder.

我想隐藏这些文件，以便用户看不到或删除它。

I want to hide these files so that the user can not see or delete it.

任何人都可以帮我解决这个问题。

Can anyone help me out to do this.

推荐答案

存储私人数据的好地方是〜/ Library / Application Support / ，这是Mac上用于此目的的文件夹。

A good place to store private data is in ~/Library/Application Support/, which is the folder used on the Mac for this purpose.

您可以使用以下命令生成此文件夹的路径：

You can generate a path to this folder using:

NSString *appSupportDir = [NSSearchPathForDirectoriesInDomains(NSApplicationSupportDirectory, NSUserDomainMask, YES) firstObject];

你必须在第一次使用时自己创建文件夹，你可以用它来做：

You'll have to create the folder yourself the first time you use it, which you can do with:

if (![[NSFileManager defaultManager] fileExistsAtPath:appSupportDir])
{
    [[NSFileManager defaultManager] createDirectoryAtPath:appSupportDir withIntermediateDirectories:YES attributes:nil error:NULL];
}

我写了一个简单的库，使这个和所有其他有用的iOS文件夹可用NSFileManager上的方法： https://github.com/nicklockwood/StandardPaths

I wrote a simple library that makes this and all other useful iOS folders available as methods on NSFileManager: https://github.com/nicklockwood/StandardPaths
