校驗工具類

• 最近總結了一下在iOS開發中用到校驗工具類，包含[網址驗證]、[郵箱驗證]、[身份證驗證]、[手機號 || 固定電話號驗證(包含400和800電話)]。
  
  
• 直接上代碼吧！

1. 網址驗證

/** 網址驗證 */
+ (BOOL)validateUrlWithUrlStr:(NSString *)urlStr {
    NSString *urlRegex = @"((http[s]{0,1}|ftp)://[a-zA-Z0-9\\.\\-]+\\.([a-zA-Z]{2,4})(:\\d+)?(/[a-zA-Z0-9\\.\\-~!@#$%^&*+?:_/=<>]*)?)|(www.[a-zA-Z0-9\\.\\-]+\\.([a-zA-Z]{2,4})(:\\d+)?(/[a-zA-Z0-9\\.\\-~!@#$%^&*+?:_/=<>]*)?)";
    NSPredicate *urlPredicate = [NSPredicate predicateWithFormat:@"SELF MATCHES %@", urlRegex];
    
    return [urlPredicate evaluateWithObject:urlStr];
}

2. 郵箱驗證

/** 郵箱驗證 */
+ (BOOL)validateEmailWithEmailStr:(NSString *)emailStr {
    NSString *emailRegex = @"[A-Z0-9a-z._%+-]+@[A-Za-z0-9.-]+\\.[A-Za-z]{2,4}";
    NSPredicate *emailPredicate = [NSPredicate predicateWithFormat:@"SELF MATCHES %@", emailRegex];
    return [emailPredicate evaluateWithObject:emailStr];
}

3. 身份證驗證

/** 身份證驗證 */
+ (BOOL)validateIdentityCardNoWithCardNoStr:(NSString *)cardNoStr {
    if (cardNoStr.length != 18) {
        return  NO;
    }
    NSArray *codeArray = [NSArray arrayWithObjects:@"7", @"9", @"10", @"5", @"8", @"4", @"2", @"1", @"6", @"3", @"7", @"9", @"10", @"5", @"8", @"4", @"2", nil];
    NSDictionary *checkCodeDic = [NSDictionary dictionaryWithObjects:[NSArray arrayWithObjects:@"1", @"0", @"X", @"9", @"8", @"7", @"6", @"5", @"4", @"3", @"2", nil] forKeys:[NSArray arrayWithObjects:@"0", @"1", @"2", @"3", @"4", @"5", @"6", @"7", @"8", @"9", @"10", nil]];
    
    NSScanner *scan = [NSScanner scannerWithString:[cardNoStr substringToIndex:17]];
    
    int val;
    BOOL isNum = [scan scanInt:&val] && [scan isAtEnd];
    if (!isNum) {
        return NO;
    }
    int sumValue = 0;
    
    for (NSInteger i = 0; i < 17; i ++) {
        sumValue += [[cardNoStr substringWithRange:NSMakeRange(i, 1)] intValue] * [[codeArray objectAtIndex:i] intValue];
    }
    
    NSString *strlast = [checkCodeDic objectForKey:[NSString stringWithFormat:@"%d", sumValue % 11]];
    
    if ([strlast isEqualToString:[[cardNoStr substringWithRange:NSMakeRange(17, 1)] uppercaseString]]) {
        return YES;
    }
    return  NO;
}

4. 手機號 || 固定電話號驗證(包含400和800電話)，這個校驗方法寫的比較開放，使用者可以根據自己需求自行修改正則表達式。

/** 手機號 || 固定電話號驗證(包含400和800電話) */
+ (BOOL)validatePhoneNumberWithPhoneNumStr:(NSString *)phoneNumStr {
    NSString *phoneRegex = @"\\d{3,4}-*\\d{7,8}|\\d{7,8}|(4|8)00-*(\\d{3})-*(\\d{4})|1\\d{10}";
    NSPredicate *predicate = [NSPredicate predicateWithFormat:@"SELF MATCHES %@", phoneRegex];
    return [predicate evaluateWithObject:phoneNumStr];
}
