UnauthorizedAccessException：访问路径拒绝Ios [英] UnauthorizedAccessException: Access to the path is denies Ios

问题描述

我知道这已经出现了一些时间，但我无法用我尝试的任何解决方案解决错误。

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

我刚刚开始测试我的应用程序 - 将屏幕截图保存到ios设备代码是 -

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;
}

要文件

    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);

假设屏幕截图是字节[]

Assuming screenshot is bytes[]

我得到了例外的主题。我正在使用Unity。

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

我得到的错误是 -

Error that I get is -

UnauthorizedAccessException：访问路径
/ var / containers / Bundle / Application / 9DA2D489-2037-451E-87D1-FA7354ECD0D1 / Documents
被拒绝。

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

推荐答案

使用保存Application.persistentDataPath 不 Application.dataPath 。请注意，您必须创建一个文件夹并保存在该文件夹中，而不是直接保存到此路径。

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.

因此，您保存的最终路径应为：

So the final path you save to should be:

Application.persistentDataPath +Yourfolder / YourFileNale.extension。

或

Application.persistentDataPath +Documents / YourFileNale.extension。

始终使用 Path.Combine 来组合路径而不是+我在上面使用过。

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