iOS之验证手机号、电子邮箱、银行卡和身份证

大多数APP都需要验证手机号、电子邮箱等等，有时候上网找也很快，但是每次都要去找，干脆写一个类来实现这些验证吧！

现附上代码：<a href = "https://github.com/smileKH/HBValidate">HBValidate</a>

demo效果图

1、手机号码验证

//手机号以13， 15，18开头，八个 \d 数字字符
    NSString *phoneRegex = @"^((13[0-9])|(15[^4,\\D])|(18[0,0-9]))\\d{8}$";
    NSPredicate *phoneTest = [NSPredicate predicateWithFormat:@"SELF MATCHES %@",phoneRegex];
    if (![phoneTest evaluateWithObject:mobile]) {
          NSString *message = @"手机号码格式不正确！";
}

2、手机号码的另一种验证

#pragma mark 电话号验证
+ (BOOL)isMobileNumber:(NSString *)mobileNum
{
    /**
     * 手机号码
     * 移动：134[0-8],135,136,137,138,139,150,151,157,158,159,182,187,188
     * 联通：130,131,132,152,155,156,185,186
     * 电信：133,1349,153,180,189
     */
    NSString * MOBILE = @"^1(3[0-9]|5[0-35-9]|8[025-9])\\d{8}$";
    
    /**
     10         * 中国移动：China Mobile
     11         * 134[0-8],135,136,137,138,139,150,151,157,158,159,182,187,188
     12         */
    NSString * CM = @"^1(34[0-8]|(3[5-9]|5[017-9]|8[278])\\d)\\d{7}$";
    
    /**
     15         * 中国联通：China Unicom
     16         * 130,131,132,152,155,156,185,186
     17         */
    NSString * CU = @"^1(3[0-2]|5[256]|8[56])\\d{8}$";
    
    /**
     20         * 中国电信：China Telecom
     21         * 133,1349,153,180,189
     22         */
    NSString * CT = @"^1((33|53|8[09])[0-9]|349)\\d{7}$";
    
    /**
     25         * 大陆地区固话及小灵通
     26         * 区号：010,020,021,022,023,024,025,027,028,029
     27         * 号码：七位或八位
     28         */
    NSString * PHS = @"^0(10|2[0-5789]|\\d{3})\\d{7,8}$";
    
    NSPredicate *regextestmobile = [NSPredicate predicateWithFormat:@"SELF MATCHES %@", MOBILE];
    
    NSPredicate *regextestcm = [NSPredicate predicateWithFormat:@"SELF MATCHES %@", CM];
    
    NSPredicate *regextestcu = [NSPredicate predicateWithFormat:@"SELF MATCHES %@", CU];
    
    NSPredicate *regextestct = [NSPredicate predicateWithFormat:@"SELF MATCHES %@", CT];
    
    NSPredicate *regextestphs = [NSPredicate predicateWithFormat:@"SELF MATCHES %@", PHS];
    
    
    if (([regextestmobile evaluateWithObject:mobileNum] == YES)
        
        || ([regextestcm evaluateWithObject:mobileNum] == YES)
        
        || ([regextestct evaluateWithObject:mobileNum] == YES)
        
        || ([regextestcu evaluateWithObject:mobileNum] == YES)
        
        || ([regextestphs evaluateWithObject:mobileNum] == YES))
        
    {
        return YES;
    }
    else
    {
        return NO;
    }
}

2、电子邮箱的验证

NSString *expression = [NSString stringWithFormat:@"^\\w+([-+.]\\w+)*@\\w+([-.]\\w+)*\\.\\w+([-.]\\w+)*$"];
    NSError *error = NULL;
    NSRegularExpression *regex = [[NSRegularExpression alloc] initWithPattern:expression
                                                                      options:NSRegularExpressionCaseInsensitive
                                                                        error:&error];
    NSTextCheckingResult *match = [regex firstMatchInString:email
                                                    options:0
                                                      range:NSMakeRange(0,[email length])];
    if (!match) {
          //邮箱格式错误!
}else{
          //验证通过
}

3、银行卡验证

NSString *bankNameregex = @"^[\u4e00-\u9fa5]{0,}$";
    NSPredicate *bankNamepredicate = [NSPredicate predicateWithFormat:@"SELF MATCHES %@", bankNameregex];
    BOOL isbankName = [bankNamepredicate evaluateWithObject:card];
    
    if (!isbankName) {
          //银行卡格式不对！
}else{
          //验证通过
}

4、身份证验证
这个代码有点长，就不贴上来了，需要的同学可以下载代码查看。
