推荐答案

首先将RegexKit添加到您的项目中. 将RegexKitLite.h导入要检查格式的类

First add RegexKit to your project. Import RegexKitLite.h to the class where you want to check the format

NSString *emailMatchstring=@"\\b([a-zA-Z0-9%_.+\\-]+)@([a-zA-Z0-9.\\-]+?\\.[a-zA-Z]{2,6})\\b";

将此字符串与UITextField的文本进行比较.

compare this string to UITextField's text.
