使用Unity将XML文件写入iOS（使用C＃） [英] Writing a XML file to iOS with Unity (Using C#)

问题描述

我正在尝试在iOS上写入XML，但这似乎是不可能的。试过几个不同的但是没有用过。

I am trying to write to a XML on iOS, but it seems to be impossible. Tried several different this but none have worked.

我已经读过iOS只对它/ Documents文件夹有写访问权限，所以我试图设置一个应用程序。 dataPath到Documents文件夹。但我在Xcode中收到此错误：

I have read that iOS only have write access to it´s /Documents folder, so I have tried to set a Application.dataPath to the Documents folder. But I get this error in Xcode :

DirectoryNotFoundException: Could not find a part of the path "/Users/mariusmathisen/Library/Application Support/iPhone       Simulator/7.1/Applications/6AE4AF70-EFDF-46F0-9947-5C0936F3AD27/DaXml.app/Data/Documents/gamexmldata.txt".

这是我写入XML的代码：

This is my code to write to XML :

lic void WriteToXml()
{
   Debug.Log ("Du nådde metoden");
   //string filepath = Application.dataPath + @"/Data/gamexmldata.xml";

   XmlDocument xmlDoc = new XmlDocument();


   GameControl.control.outputXml = "Du nådde WriteXML";
   if(File.Exists(Application.dataPath + "/Documents/gamexmldata.txt"))
   {
     Debug.Log("Filen Fantes");
     GameControl.control.outputXml = "DU ER I Writetoxml og filen fantes";



     xmlDoc.Load(Application.dataPath + "/Documents/gamexmldata.txt");
     //xmlDoc.Load(filepath);

     XmlElement elmRoot = xmlDoc.DocumentElement;

     // elmRoot.RemoveAll(); // remove all inside the transforms node.

     XmlElement elmNew = xmlDoc.CreateElement("rotation"); // create the rotation node.

     XmlElement rotation_X = xmlDoc.CreateElement("x"); // create the x node.
     rotation_X.InnerText = x; // apply to the node text the values of the variable.

     XmlElement rotation_Y = xmlDoc.CreateElement("y"); // create the y node.
     rotation_Y.InnerText = y; // apply to the node text the values of the variable.

     XmlElement rotation_Z = xmlDoc.CreateElement("z"); // create the z node.
     rotation_Z.InnerText = z; // apply to the node text the values of the variable.
     XmlElement navnElement = xmlDoc.CreateElement("name");
     navnElement.InnerText = navn;

     GameControl.control.inputXml = navnElement.InnerText;

     elmNew.AppendChild(rotation_X); // make the rotation node the parent.
     elmNew.AppendChild(rotation_Y); // make the rotation node the parent.
     elmNew.AppendChild(rotation_Z); // make the rotation node the parent.
     elmNew.AppendChild(navnElement);
     elmRoot.AppendChild(elmNew); // make the transform node the parent.

     xmlDoc.Save(Application.dataPath + "/Documents/gamexmldata.txt"); // save file.
     Debug.Log("Filen er lagret");
   }else{

     xmlDoc.Save(Application.dataPath + "/Documents/gamexmldata.txt");
   }
}

有什么建议我为什么不能得到要写入iOS及其文件夹的XML？我做错了什么？

Are there any suggestion to why I can´t get the XML to write to iOS and it´s folder? What am I doing wrong?

推荐答案

我认为问题在于你的路径不完全正确。

I think that the problem lies in the fact that your path is not completely correct.

根据Apple的说法，您需要将文件写入：

According to Apple you are required to write the file into:

/Documents/gamexmldata.txt

/Documents/gamexmldata.txt

而不是你把它写成：

/ [AppName] .app / Documents / gamexmldata.txt

/[AppName].app/Documents/gamexmldata.txt

要解决此问题，您可以使用以下内容：

To solve this you can use the following:

fileSaveLocation = Application.dataPath.Replace（/ [AppName] .app /数据，/文档/ gamexmldata.txt）;

fileSaveLocation = Application.dataPath.Replace( "/[AppName].app/Data", "/Documents/gamexmldata.txt" );

并确保 - [AppName]这里是您在构建应用程序时选择的开发应用ID名称（不是应用程序的名称，但它是Apple的ID名称。）

And to make sure - [AppName] here is the development app Id name you selected when you build the application (not the 'name' of the application, but it's Id name with Apple).

有关Apple所需位置的文档，请访问：

Documentation about the required location by Apple can be found here:
