iOS正则表达式(亲测,持续更新)

先来说说判断方法,书写不简介但是好理解:

-(BOOL)isRealNmaeString:(NSString *)str{NSString *pattern = @"填写正则表达式";NSPredicate *pred = [NSPredicate predicateWithFormat:@"SELF MATCHES %@", pattern];BOOL isMatch = [pred evaluateWithObject:str];if (str.length==0){return NO;}else if (!isMatch){return NO;}else{return YES;}
}

1,只能输入中文:^[\u4e00-\u9fa5]+$

2,输入价格,如33.33 :^(([0-9]+\\.[0-9]*[1-9][0-9]*)|([0-9]*[1-9][0-9]*\\.[0-9]+)|([0-9]*[1-9][0-9]*))$

3,验证手机号:1[3578][0-9]{9}$

持续更新中...
