实际上，这只是一个警告。但你可以修复它。

facebook插件调用的地方有好几个

FBBuildVersionAttribute.GetVersionAttributeOfType(typeof(AbstractFacebook));

所以首先，您需要将FBBuildVersionAttribute 修改为：

// we are going to apply this attribute to Class
// instead of Assembly
// also make it inheritable for all implementations
[AttributeUsage(AttributeTargets.Class, Inherited = true)]
public class FBBuildVersionAttribute : Attribute
{
    private DateTime buildDate;
    private string buildHash;
    private string buildVersion;

    private string sdkVersion;

    public DateTime Date { get { return buildDate; } }
    public string Hash { get { return buildHash; } }
    public string SdkVersion { get { return sdkVersion; } }
    public string BuildVersion { get { return buildVersion; } }

    public FBBuildVersionAttribute(string sdkVersion, string buildVersion)
    {
        this.buildVersion = buildVersion;
        var parts = buildVersion.Split('.');
        buildDate = DateTime.ParseExact(parts[0], "yyMMdd", System.Globalization.CultureInfo.InvariantCulture);
        buildHash = parts[1];

        this.sdkVersion = sdkVersion;
    }

    public override string ToString()
    {
        return buildVersion;
    }

    public static FBBuildVersionAttribute GetVersionAttributeOfType(Type type)
    {
        foreach (FBBuildVersionAttribute attribute in getAttributes(type))
        {
            return attribute;
        }
        return null;
    }

    private static FBBuildVersionAttribute[] getAttributes(Type type)
    {
        if (type == null)
            throw new ArgumentNullException("type");

        // we want to get attributes from type instead of assmebly
        return (FBBuildVersionAttribute[])(type.GetCustomAttributes(typeof(FBBuildVersionAttribute), false));
    }
}

不，您只需将此属性添加到AbstractFacebook：

[FBBuildVersionAttribute("7.0.1", "150604.98558e55096475c")]
public abstract class AbstractFacebook : MonoBehaviour
{
    // ...
}

请注意，98558e55096475c 部分是垃圾字符串。这不是实际的构建哈希，因为我没有。

获取最新版本的 FB Unity SDK。更改日志说它现在已修复。
