ios使用常用正则表达式验证密码身份证手机号

在项目中,我们在验证用户的输入,最简单的方法就是使用正则表达式了,ios系统也提供很方便的方法,让我们可以轻松的来验证用户名,密码,身份证好 ,手机号等;

下面附上我在项目中用到的正则表达式的验证方法,

由于比较常用,大家最好封装成+静态的方法,便于使用:

我把常用的方法,使用静态方法封装到一个 Utils类里面,直接使用类名调用即可:

原文地址:

使用方法示例:

if ([Utils checkTelNumber:@"18801112020"]) //匹配结果,为YES{NSLog(@"手机号格式正确");}else//匹配结果为NO{NSLog(@"手机号格式错误");}
