iOS中的富文本编辑器
我正在寻找一个示例项目，该项目应具有基本的富文本编辑功能（粗体，斜体，下划线，对齐，附加图像）。
I am looking for a sample project which should have basic rich text editing features (Bold,Italic,Underline,Alignment,Attaching images).
我浏览了Google搜索结果有几个编辑器可用于 iOS 但这些都是使用 UIWebView 与一起开发的HTML 。我正在寻找使用 UITextView 开发的那个以及 iOS 6 和 7 （ NSAttributedString ， NSTextattAchment ）
I went through Google search results there are several editors available for iOS but those all are developed by using UIWebView with HTML. I am looking for the one which developed by using UITextView along with new features in iOS 6 and 7(NSAttributedString, NSTextattAchment)
如果你知道任何开源代码或教程，请指导我吗？
Can please guide me if you know any open source code or tutorial?
提前致谢！
在iOS开发网站上没有可用于富文本的示例项目，但是如果您喜欢UITextView实现，那么几乎没有源代码替代品，如iOS-Rich-Text-Editor和FastTextView。
There no sample project for rich text that available on iOS Dev website, However if you like a UITextView implementation there few open-source alternatives such as iOS-Rich-Text-Editor and FastTextView.
iOS-Rich-Text-Editor
RichTextEditor for iPhone& iPad支持额外的加载，如粗体，斜体，下划线，StrikeThrough，字体，段落缩进/突出等。检查示例它使用UITExtview。
