三、添加导出字体设置信息菜单

using UnityEngine;
using UnityEditor;
using System.Collections;
using System.Collections.Generic;
using System;
using System.IO;
 
static public class UIToolsEditor 
{
    #region UILabel 导出字体样式设置
    [MenuItem("NGUI/Label Setting/Output Setting")]
    static void LabelOutputSetting() {
        GameObject[] gameObjects = Selection.gameObjects;
        if (null == gameObjects)
            return;
 
        StringBuilder sb = new StringBuilder();
        for (int i = 0; i < gameObjects.Length; i++) {
            GameObject go = gameObjects[i];
            UILabel label = go.GetComponent<UILabel>();
            if (null == label)
                continue;
 
            CommonFontStyleJson cfs = new CommonFontStyleJson();
            cfs.fontSize = label.fontSize;
            cfs.applyGradient = label.applyGradient;
            cfs.gradientTop = new CommonFontStyleColor(label.gradientTop.r, label.gradientTop.g, label.gradientTop.b, label.gradientTop.a);
            cfs.gradientBottom = new CommonFontStyleColor(label.gradientBottom.r, label.gradientBottom.g, label.gradientBottom.b, label.gradientBottom.a);
            cfs.color = new CommonFontStyleColor(label.color.r, label.color.g, label.color.b, label.color.a);
            cfs.effectStyle = label.effectStyle.ToString();
            cfs.effectColor = new CommonFontStyleColor(label.effectColor.r, label.effectColor.g, label.effectColor.b, label.effectColor.a);
            Debug.Log(LitJson.JsonMapper.ToJson(cfs, true));
 
            sb.AppendLine(LitJson.JsonMapper.ToJson(cfs, true));
        }
 
        if (sb.Length > 0)
        {
            string font_str = sb.ToString();
            byte[] font_bytes = Encoding.UTF8.GetBytes(font_str.ToCharArray());
 
            string font_file = Application.dataPath + "/NGUI/fontstyle_tmp.txt";
            FileStream fs = File.OpenWrite(font_file);
            fs.Write(font_bytes, 0, font_bytes.Length);
            fs.Flush();
            AssetDatabase.Refresh();
            Debug.Log("Output: "+font_file);
        }
    }
	
	[MenuItem("NGUI/Label Setting/Reload fontstyle.txt")]
    static void ReloadFontStyleConfig() {
        UILabel.LoadFontStyleConfig();
    }
 
    public class CommonFontStyleJson {
        public int fontSize;
        public bool applyGradient;
        public CommonFontStyleColor gradientTop;
        public CommonFontStyleColor gradientBottom;
        public CommonFontStyleColor color;
        public string effectStyle;
        public CommonFontStyleColor effectColor;
        public string description = "描述信息";
    }
 
    public class CommonFontStyleColor {
        //LitJson不支持float
        public double r;
        public double g;
        public double b;
        public double a;
 
        public CommonFontStyleColor(float r, float g, float b, float a) {
            this.r = r;
            this.g = g;
            this.b = b;
            this.a = a;
        }
    }
    #endregion
}
