问题描述

我一直在寻找一个解决方案来解决如何授予用户在 UITextView 中加下划线，斜体和粗体文字的能力，但是还没有能力找到一个坚实的解决方案。我已经意识到我将需要使用 NSAttributedString ，但我不确定如何创建 UI 并格式化字符串，所以我能够将其保存到数据库。如果你能指出我正确的方向，将非常感激。谢谢！

I have been searching for quite a while for a solution as to how to grant users the ability to underline, italicize and bold text in a UITextView but have not been able to find a solid solution. I have realized that I will need to use an NSAttributedString but am not sure as to how to create the UI and format the string so I am able to save it to a database. If you could point me in a proper direction that would be greatly appreciated. Thanks!

推荐答案

UI只是一个普通的可编辑UITextView，其中 allowsEditingTextAttributes 设置为 true 。

The UI is simply an ordinary editable UITextView with allowsEditingTextAttributes set to true.

您如何保存取决于您，但最通用的解决方案可能是取出UITextView的 attributedText ，将其存档到NSData（现在称为Swift中的数据），并将其保存。

How you save is up to you, but the most universal solution is probably to pull out the UITextView's attributedText, archive it into an NSData (now known as Data in Swift), and save it off.
