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.直接贴代码,
using UnityEngine;using System.Collections;using System.Collections.Generic;using System.IO;using iTextSharp.text.pdf;using iTextSharp.text;using System.Text.RegularExpressions;using System.Data.OracleClient;using System;//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<string> mChildObjs = new List<string>(); 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; } //每行五个 还有问题,由于需求以及时间关系,没时间去管了 谁看到了可以帮忙解决下,.thanks List<PdfInformation> mGoodsInfoList = new List<PdfInformation>();
