NGUI的多语言处理

（当前NGUI 版本为3.5.8）

先看几个SCRIPT文件：

Localization.cs （静态类）:: 从text asset中读取本地化的文本文件，并解析出相关的字符串信息。所得的KEY/VALUE数据存储在 Dictionary<string, string> mOldDictionary结构中。

UILocalize.cs:: 用于对UIWidget进行本地化。

关键代码在：

void Start ()
	{
#if UNITY_EDITOR
		if (!Application.isPlaying) return;
#endif
		mStarted = true;
		OnLocalize();
	}

	/// <summary>
	/// This function is called by the Localization manager via a broadcast SendMessage.
	/// </summary>

	void OnLocalize ()
	{
		// If no localization key has been specified, use the label's text as the key
		if (string.IsNullOrEmpty(key))
		{
			UILabel lbl = GetComponent<UILabel>();
			if (lbl != null) key = lbl.text;
		}

		// If we still don't have a key, leave the value as blank
		if (!string.IsNullOrEmpty(key)) <span style="color:#ff0000;">value = Localization.Get(key)</span>;
	}
           

一般在每个UILABEL控件中都要添加一个 UILocalize.cs的SCRIPT文件。
