校验工具类

最近总结了一下在iOS开发中用到校验工具类，包含网址验证、邮箱验证、身份证验证、手机号 || 固定电话号验证(包含400和800电话)。 直接上代码吧！

1. 网址验证

/** 网址验证 */ + (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. 邮箱验证

/** 邮箱验证 */ + (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. 身份证验证

/** 身份证验证 */ + (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. 手机号 || 固定电话号验证(包含400和800电话)，这个校验方法写的比较开放，使用者可以根据自己需求自行修改正则表达式。

/** 手机号 || 固定电话号验证(包含400和800电话) */ + (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]; }
