你必须通过Quartz2d来开发它。换句话说，你可以通过处理UIView的CGContext。请参阅 Quartz2d 编程指南。例如，您可以通过提供粗体字体
You have to develop it through Quartz2d.In otherwords ,you can through handling CGContext of UIView. see the Quartz2d programming guide.for example you can give bold font through
文本编辑器专业版似乎具有这些功能。不过相当昂贵： http://itunes.apple.com /dk/app/text-editor-pro/id316815447?mt=8
Text Editor Pro seems to have those features. Pretty expensive though: http://itunes.apple.com/dk/app/text-editor-pro/id316815447?mt=8
Oliver Drobnik（又名 Cocoanetics）正在开发 iOS 的富文本编辑器。
不幸的是，它不会是免费的。然而，他在这里发布了相当大的代码块，作为他的富编辑器的基础： https://github.com/Cocoanetics/NSAttributedString-Additions-for-HTML
它采用 HTML 并将其转换为核心文本。那里有很多艰苦的工作。
它本身并不是一个丰富的编辑器，但正如我所说，它是一个丰富的编辑器的基础。如果你不想在奥利弗完成后付钱给他，你可以用它来写你自己的。您可以在这里查看 Oliver 一直在做什么： http:// /www.cocoanetics.com/2011/01/rich-text-editing-on-ios/
Oliver Drobnik (aka Cocoanetics) is working on a rich text editor for iOS.
It won't be free, unfortunately. However, he has released a sizeable chunk of code that serves as the foundation of his rich editor here: https://github.com/Cocoanetics/NSAttributedString-Additions-for-HTML
It takes HTML and turns it into core text. A lot of hard work right there.
That, on its own, is not a rich editor, but like I said, it serves as the foundation of one. You could use it to write your own, if you don't want to pay up for Oliver's when he's finished. You can see what Oliver has been working on here: http://www.cocoanetics.com/2011/01/rich-text-editing-on-ios/
