Unity教程之-Unity3d导出pdf文件

 

本篇unity3d教程,我们来学习一个开发技巧–在Unity3d导出pdf文件,下面开始,unity生成pdf格式,首先需要导入iTextSharp.dll ,下面是我写的一些方法,可以直接用。废话不说,直接贴代码!


using UnityEngine;
using System.Collections;
using System.Collections.Generic;
using System.IO;
using iTextSharp.text.pdf;
using iTextSharp.text;

//需要用到的数据结构
public class PdfUserInformation
{
public string goodsName;
public string youzhanType;
public string cvsLevel;
public string writeTime;
public string creater;
public string creatTime;
};
//数据结构
public  class PdfInformation
{
public string mID;
public string mName;
public string mReserve;
//  ....
};

public class PDFMakerManager  {

public static PDFMakerManager PDFInstance;
public static PDFMakerManager createPDFMakerManager()
{
if(PDFInstance==null)
{
PDFInstance = new PDFMakerManager ();
}

return PDFInstance;
}

//获取物品的子物体名字 通过子物体的名字获取物体  返回物体的链表
public List<PdfInformation> getObjChildsName(Transform mParentObj)
{

if(mParentObj!=null)
{

List<PdfInformation> mInfoList = new List<PdfInformation>();
foreach (Transform mChildTransform in mParentObj)
{
mChildObjs.Add(mChildTransform.gameObject.name);
Debug.Log(mChildTransform.gameObject.name);
}
//获取  数据库  信息
getPdfDatasFromDB();
//通过子物体的名字 获取物体信息
for (int i = 0; i < mChildObjs.Count; i++)
{
mInfoList.Add(mDirectoryData[mChildObjs[i]]);
}
return mInfoList;
}
return null;
}
