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 iTextSharp.text;

//数据结构

	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]]);
