请注意，此问题尚未完全解决，但OP似乎已取得良好的开端.希望您可以从讨论中获得一些线索.
Note that the issue is not fully solved there, but it seems the OP got a good head start. Hopefully you can take some clues from the discussion.
这里是一个答案:
NSTextAttachment保存附件的内容；这就是价值 的NSAttachmentAttributeName属性的 属性字符串中的NSAttachmentCharacter.内容是 通常由NSFileWrapper给出，但这不是必需的；你可以 使用零文件包装器创建一个空的NSTextAttachment.
NSTextAttachment holds the contents of an attachment; it is the value of the NSAttachmentAttributeName attribute for the NSAttachmentCharacter in the attributed string. The contents are usually given by an NSFileWrapper, but this is not required; you can create an empty NSTextAttachment with a nil file wrapper.
NSTextAttachmentCell处理以下内容的显示和用户交互: 依恋.默认情况下，NSTextAttachment将创建一个 NSTextAttachmentCell来显示自身，具体取决于 附件;在一般情况下，这将只是一个图像单元 显示图标.
NSTextAttachmentCell handles display and user interaction for the attachment. By default an NSTextAttachment will create an NSTextAttachmentCell to display itself, depending on the contents of the attachment; in the generic case this will just be an image cell displaying an icon.
但是，如果您愿意，可以提供一个自定义NSTextAttachmentCell用于 您的附件.它不必是该类的成员 NSTextAttachmentCell;它只需要符合 NSTextAttachmentCell协议.实际上，即使那不是严格的 必要的;它只需要实现一些基本方法即可 尺寸和绘图.大多数单元已经这样做了.
If you wish, however, you can supply a custom NSTextAttachmentCell for your attachment. It need not be an member of the class NSTextAttachmentCell; it only needs to conform to the NSTextAttachmentCell protocol. Actually, even that is not strictly necessary; it only needs to implement a few of the basic methods for sizing and drawing. Most cells already do this.
但是，您将需要自己处理鼠标事件.这 您可能要实现的方法是 wantToTrackMouseForEvent:inRect:ofView:atCharacterIndex:和 trackMouse:inRect:ofView:atCharacterIndex:.此处的字符索引 应该让您确定文本的哪一部分是相关的.
You will, however, need to deal with mouse events yourself. The methods you'll probably want to implement would be wantsToTrackMouseForEvent:inRect:ofView:atCharacterIndex: and trackMouse:inRect:ofView:atCharacterIndex:. The character index here should let you determine which portion of the text is relevant.
