推荐答案

到目前为止，我找到的最好的解决方案（以及最终得到的解决方案）是添加 RegexKitLite 到可以通过NSString类别访问正则表达式的项目。

The best solution I have found so far (and the one I ended up going with) is to add RegexKitLite To the project which gives access to regular expressions via NSString Categories.

添加到项目很容易项目，一旦完成，任何正则表达式电子邮件验证逻辑都将起作用。

It is quite painless to add to the project and once in place, any of the regular expression email validation logic will work.
