有没有一种方法可以让iOS的自动更正忽略UITextView中的单个单词或正则表达式? [英] Is there a way to have iOS' autocorrect ignore a single word or regex in a UITextView?

问题描述

我正在构建文本视图来编写状态消息，它的功能之一是在状态消息的文本中包含#hashtags.

I'm building a textview to compose status messages, and one of the functions it has is to include #hashtags within the text of a status message.

但是，这些#hashtags通常不是实际的 words ，因此，一旦输入了井号标签，iOS的自动更正功能会使其带有红色下划线.

However, these #hashtags often aren't actual words, so iOS' autocorrect functionality causes them to appear with a red underline once the hashtag has been typed.

(例如:#seafair2014，#wwdc和其他非单词的标签)

(For example: #seafair2014, #wwdc, and other non-word hashtags)

是否可以将术语临时添加到iOS词典中，以忽略任何#hashtag或@username错字，但仍提供其余UITextView的拼写检查?

Is there a way to temporarily add a term to the iOS dictionary, so as to ignore any #hashtag or @username typos but still provide spell-checking for the rest of the UITextView?

推荐答案

使用+[UITextChecker learnWord:].您可以收听更改事件并动态添加标签词.

Use +[UITextChecker learnWord:]. You can listen to change events and dynamically add hashtag words.
