在iOS中创建RTF，DOC或DOCX

Question

我想用iOS-App创建以下文件类型之一：RTF，DOC或DOCX。 用户应该能够写文字还有添加图像它。 UI的构建不是问题，只是创建文件。

有没有最佳做法来做到这一点？

第三方框架是一个选项，但我想自己做。

感谢

我可以帮你的docx文件（RTF文件更容易和DOC文件是完全一样的docx但不太良好的组织）

我认为你能做的最好的是开始打开一个docx文件到文本编辑器。您首先要解压缩该文件。

您将有以下文件夹

>_rels 
>customXML 
>docProps 
>word: 
    >_rels: 
     document.xml.rels //this document tells word where the images are situated 
    >media //Here are the images 
    >theme 
    >document.xml //Here is the actual content of the file 
    >header1.xml //Here is the content of your header 
>[Content_Types].xml 

要插入一些文字，看看在document.xml中的文件。

<?xml version="1.0" encoding="UTF-8" standalone="yes"?> 
<w:document mc:Ignorable="w14 wp14" xmlns:m="http://schemas.openxmlformats.org/officeDocument/2006/math" xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006" xmlns:o="urn:schemas-microsoft-com:office:office" xmlns:r="http://schemas.openxmlformats.org/officeDocument/2006/relationships" xmlns:v="urn:schemas-microsoft-com:vml" xmlns:w="http://schemas.openxmlformats.org/wordprocessingml/2006/main" xmlns:w10="urn:schemas-microsoft-com:office:word" xmlns:w14="http://schemas.microsoft.com/office/word/2010/wordml" xmlns:wne="http://schemas.microsoft.com/office/word/2006/wordml" xmlns:wp="http://schemas.openxmlformats.org/drawingml/2006/wordprocessingDrawing" xmlns:wp14="http://schemas.microsoft.com/office/word/2010/wordprocessingDrawing" xmlns:wpc="http://schemas.microsoft.com/office/word/2010/wordprocessingCanvas" xmlns:wpg="http://schemas.microsoft.com/office/word/2010/wordprocessingGroup" xmlns:wpi="http://schemas.microsoft.com/office/word/2010/wordprocessingInk" xmlns:wps="http://schemas.microsoft.com/office/word/2010/wordprocessingShape"> 
<w:body> 
.... 
</w:body> 
</w:document> 

Docx使用<w:p>标签为段落。 它使用<w:r>表示具有一种格式的文本块。 它使用<w:t>的实际文本

这将产生一个简单的Hello World

<w:p w:rsidP="00CA7135" w:rsidR="00137C91" w:rsidRDefault="00137C91"> 
    <w:r> 
     <w:t>Hello world</w:t> 
    </w:r> 
</w:p> 

对于图像，你将不得不把更多的信息：

  <w:p w:rsidP="00CA7135" w:rsidR="00B12C70" w:rsidRDefault="00B12C70"> 
       <w:r> 
        <w:rPr> 
         <w:noProof/> 
         <w:lang w:eastAsia="fr-FR"/> 
        </w:rPr> 
        <w:drawing> 
         <wp:inline distB="0" distL="0" distR="0" distT="0" wp14:anchorId="7CC0BC42" wp14:editId="09031C8D"> 
          <wp:extent cx="866775" cy="1323975"/> 
          <wp:effectExtent b="9525" l="0" r="9525" t="0"/> 
          <wp:docPr id="13" name="Image 13"/> 
          <wp:cNvGraphicFramePr> 
           <a:graphicFrameLocks noChangeAspect="1" xmlns:a="http://schemas.openxmlformats.org/drawingml/2006/main"/> 
          </wp:cNvGraphicFramePr> 
          <a:graphic xmlns:a="http://schemas.openxmlformats.org/drawingml/2006/main"> 
           <a:graphicData uri="http://schemas.openxmlformats.org/drawingml/2006/picture"> 
            <pic:pic xmlns:pic="http://schemas.openxmlformats.org/drawingml/2006/picture"> 
             <pic:nvPicPr> 
              <pic:cNvPr id="0" name=""/> 
              <pic:cNvPicPr/> 
             </pic:nvPicPr> 
             <pic:blipFill> 
              <a:blip r:embed="rId15"/> 
              <a:stretch> 
               <a:fillRect/> 
              </a:stretch> 
             </pic:blipFill> 
             <pic:spPr> 
              <a:xfrm> 
               <a:off x="0" y="0"/> 
               <a:ext cx="866775" cy="1323975"/> 
              </a:xfrm> 
              <a:prstGeom prst="rect"> 
               <a:avLst/> 
              </a:prstGeom> 
             </pic:spPr> 
            </pic:pic> 
           </a:graphicData> 
          </a:graphic> 
         </wp:inline> 
        </w:drawing> 
       </w:r> 
      </w:p> 

的ID（13）内这个标签：<wp:docPr id="13" name="Image 13"/>必须是唯一的。 Word将会查看document.xml.rels以查看图像的存储位置。

Document.xml.rels：

，你可以看到，这个标签，id为13的图像在目标属性locafted。

<Relationship Id="rId13" Target="media/image5.png" Type="http://schemas.openxmlformats.org/officeDocument/2006/relationships/image"/>
