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...
