UnauthorizedAccessException: Access to the path is denies Ios

Question

I know this has come up some time but I am not able to solve the error with any of the solutions I tried.

I just started testing my application - to save a screenshot to ios device Code is -

string GetiPhoneDocumentsPath()
{
    string path = Application.dataPath.Substring(0, Application.dataPath.Length - 5);
    path = path.Substring(0, path.LastIndexOf("/"));
    return path + "/Documents/";
}

string CreateImagesDirectory(string documentsPath) {
    //System.IO.File.SetAttributes (documentsPath, FileAttributes.Normal);
    string imagePath = documentsPath +"magicimages/";
    if (Directory.Exists(imagePath)) {return imagePath;}
    DirectoryInfo t = new DirectoryInfo(documentsPath);
    //Directory.CreateDirectory(imagePath);
    t.CreateSubdirectory("magicimages");
    System.IO.File.SetAttributes (imagePath, FileAttributes.Normal);

    return imagePath;
}

To wite the file

    Debug.Log("Do nothing actually as we need to save to persistent data path");
        string documentsPathIphone = GetiPhoneDocumentsPath();
        Debug.Log ("document path" + documentsPathIphone);
        string imagePath = CreateImagesDirectory (documentsPathIphone);
        //Path = imagePath + fileName;
        Debug.Log ("path iphone" + Path);
        Debug.Log("Appllicarion data path -->" + Application.dataPath);
        //string savepath = Application.dataPath.Replace ("game.app/Data", "/Documents/");
        System.IO.File.WriteAllBytes (System.IO.Path.Combine(Path , fileName), screenshot);

Assuming screenshot is bytes[]

I get the exception that as in subject. I am using Unity.

Error that I get is -

UnauthorizedAccessException: Access to the path "/var/containers/Bundle/Application/9DA2D489-2037-451E-87D1-FA7354ECD0D1/Documents" is denied.

Solution

You save with Application.persistentDataPath not Application.dataPath. Note that you must create a folder and save inside that folder instead of saving directly to this path.

So the final path you save to should be:

Application.persistentDataPath+"Yourfolder/YourFileNale.extension".

or

Application.persistentDataPath+"Documents/YourFileNale.extension".

Always use Path.Combine to Combine paths instead of "+" I used above.

Before I can create the directory I get the error in CreateImagesDirectory() so even the folder creation is not happening

What do you expect me to do if you get an error and don't post it? ............ if (!Directory.Exists(Path.GetDirectoryName(yourPath))) { Directory.CreateDirectory(Path.GetDirectoryName(yourPath)); }...... then ....... File.WriteAllBytes(yourPath, yourData);

ok, I updated the methods with the code and error that I am getting. the exists option is available in CreateImagesDirectory method. Can you please check now?

[Programmer]

You also need to add Edit and add the new code ans also mention the line of coed that's causing that error.

I solved it actually now. The issue was with datapath vs persistentdata path. using persistent one resolved the issue. Thanks anyways

This is what I said in my answer. I said you should use Application.persistentDataPath not Application.dataPath. I don't know what you have been using since then.
