如何在Objective-C for iOS中创建和保存.rtf，.doc，.docx [英] How to create and save a .rtf, .doc, .docx in Objective-C for iOS

问题描述

我希望在iPad（iOS）上创建并保存rtf，doc或docx文件。

I am looking to create and save either a rtf, doc or docx file on an iPad (iOS).

情节是我们想帮助用户在他们的iPad上创建内容，然后让他们通过电子邮件发送这个可编辑的文档跨平台（OS X， WIN）。

The scenario is that we'd like to assist a user in creating content on their iPad and then let them email this as an editable document cross-platform (OS X, WIN).

我对除rtf，doc或docx文件格式之外的其他解决方案持开放态度。

I am open to other solutions besides the rtf, doc or docx file format.

谢谢，

James

推荐答案

RTF将是最简单的，因为它是纯文本格式。它有点像HTML，但没有关闭标签。 这里是一个用于编写RTF的类，但它需要很多依赖项来自框架中的其他地方。

RTF is going to be the easiest, because it's a plain text format. It's kind of like HTML, but without closing tags. Here is a class for writing an RTF, but it requires a lot of dependencies from elsewhere in the framework.

DOCX相当困难。它实际上是一个zip文件，包含一些XML文件。您可以通过将.docx扩展名更改为.zip并解压缩来自行检查格式。但即使XML是一种相当容易编写的格式，文本属性的组织方式仍然相当复杂。此外，我记得它必须以非常具体的方式进行拉链才能正确读取。

DOCX would be rather difficult. It's actually a zip file, containing a few XML files. You can examine the format yourself by changing the .docx extension to .zip and unzipping it. But even though XML is a fairly easy to write format, the way the text attributes are organized is still rather complicated. Also, I recall that it has to be zipped in a very specific way to be read properly.

至于DOC，这将是非常困难的，因为它是如此复杂的格式。您可以查看一些开源项目，例如 Abiword 或 Word2x 。请小心使用他们的代码，因为许可证可能与App Store规则不一致。

As for DOC, it will be very difficult because it's such a complex format. You could look into some open source projects, like Abiword or Word2x. Be careful using their code because the licenses may not agree with the App Store rules.
