XML Decentralization无法在Windows中运行的Unity iOS构建中运行

标签： ios xml unity3d serialization xml-deserialization

我正在获取有关通过放置在构建的自定义文件夹中的XML设置UI和消息的详细信息。它可以在Windows版本中正常运行，而不是在iOS中。我要附加使用的脚本。

XML操作

using System.IO;
using System.Xml.Serialization;
using UnityEngine;
using System.Xml;

public class XMLOperations
{
    public static void Serialize(object item, string path)
    {
        XmlSerializer serializer = new XmlSerializer(item.GetType());
        StreamWriter writer = new StreamWriter(path);
        serializer.Serialize(writer.BaseStream, item);
        writer.Close();
    }

    public static T Deserialize<T>(string path)
    {
        XmlSerializer serializer = new XmlSerializer(typeof(T));
        StreamReader reader = new StreamReader(path);
        T deserialized = (T)serializer.Deserialize(reader.BaseStream);
        reader.Close();
        Debug.Log(deserialized);
        return deserialized;
    }
}

提取XML的详细信息

using System.Xml.Serialization;
using System.IO;
using System.Text;

[XmlRoot("WelcomePage")]
public class WelcomePage
{
    [XmlElement("Background")]
    public GenericDetails background;
    [XmlElement("MotionBand")]
    public GenericDetails motionBand;
    [XmlElement("DefaultLogo")]
    public GenericDetails defaultLogo;
    [XmlElement("WelcomeMessage")]
    public GenericDetails welcomeMessage;
    [XmlElement("VisitName")]
    public GenericDetails visitName;
    [XmlElement("VisitorName")]
    public GenericDetails[] visitorName;
    [XmlElement("Date")]
    public GenericDetails date;
    [XmlElement("Location")]
    public GenericDetails location;
    [XmlElement("CustomerLogo")]
    public GenericDetails customerLogo;
}

public class GenericDetails
{
    [XmlElement("ImagePath")]
    public string path;
    [XmlElement("Rect")]
    public string rect;
    [XmlElement("BGColor")]
    public string bgColor;
    [XmlElement("TextAlignment")]
    public string alignment;
    [XmlElement("TextColor")]
    public string textColor;
    [XmlElement("BGTransparency")]
    public float bgTransparency;
    [XmlElement("MaxFontSize")]
    public int maxFontSize;
}

public class WelcomePageSetup
{
    public WelcomePageSetup(string url)
    {
        if (!File.Exists(url))
        {
            if (!Directory.Exists(Path.GetDirectoryName(url)))
                Directory.CreateDirectory(Path.GetDirectoryName(url));

            File.WriteAllText(url, WelcomeLayout._main.welcomePageDetails, Encoding.UTF8);
        }
    }
}

带有详细信息的XML文件

请务必检查脚本并帮助我解决问题。它可以在独立版本中正常工作，我可以编辑XML详细信息，以反映UI。在iOS版本中，它不进行反序列化，由于未对细节进行反序列化和检索，带有XML详细信息的函数出错。

iOS中显示的异常-Xcode

2 个答案:

答案 0 :(得分：1)

您在Unity用于AOT平台（如iOS）的.NET配置文件实现中遇到了限制。在Unity 2018.3和更高版本（尚未发布）中，我们已纠正了此问题，因此Unity中的任何Api兼容性级别选项都将使用AOT友好的类库实现。

在Unity 2018.2和更早版本中，您需要根据确定使用.NET Standard 2.0 Api兼容性级别。

通常，.NET Standard 2.0 Api兼容性级别是正确的选择。它包含大多数Unity项目中使用的大多数API，并且它将生成比.NET 4.x Api兼容级别小的代码。

答案 1 :(得分：0)

我已经将API兼容性级别从4.x切换到了.NET Standard 2.0，
