1. Verification regularity of mobile phone number
Regular expression:
^((13[0-9])|(15[^4,\\D])|(18[0,0-9]))\\d{8}$
Detailed explanation
Explanation:
•^…$: ^: Start
$: End
In the middle is the string to be processed
(13 [0-9]): The number starting with 13 and the next digit is between 0 and 9 13: Start with 13
[0-9]: Partition syntax, 13 followed by a number between 0-9
Or (or), or operation is performed on the two matching conditions before and after
• (15 [^ 4\\ D]): Beginning with 15, the next digit is 0-9 except 4 15: Start with 15
[^ 4\\ D]: All numbers from 0 to 9 except 4
^: Non-^ 4 here is any character except 4
\ D:\ D is not a number `\ ` is an escape character
• (18 [0, 2, 5-9]): A number that begins with 18 and the next 1 bit is 0 or 2 or between 5-9
•\ d {8}: 8 digits from 0 to 9 \ d: Numbers between 0 and 9
{8}: Match 8 times
Use of regular expressions:
+ (BOOL)isMobileNumber:(NSString *)mobileNumber
{
// Mobile phone number to 13 , 15 , 18 At the beginning, 8 A \d Numeric character
NSString *phoneRegex = @"^((13[0-9])|(15[^4,\\D])|(18[0,0-9]))\\d{8}$";
NSPredicate *phoneTest = [NSPredicate predicateWithFormat:@"SELF MATCHES %@",phoneRegex];
return [phoneTest evaluateWithObject:mobileNumber];
}2. ID card verification
/**
* ID number
* @param NSString ID number string
* @return Whether it is an ID number
* d{14} 14 Bit number
*/
+ (BOOL) validateIdentityCard: (NSString *)identityCard
{
BOOL flag;
if (identityCard.length <= 0) {
flag = NO;
return flag;
}
NSString *regex2 = @"^(\\d{14}|\\d{17})(\\d|[xX])$";
NSPredicate *identityCardPredicate = [NSPredicate predicateWithFormat:@"SELF MATCHES %@",regex2];
return [identityCardPredicate evaluateWithObject:identityCard];
}/**
* Accurately verify the ID number
* @param IdentityNum ID number
* @return Is it an ID number
*/
+(BOOL)isValidWithIdentityNum:(NSString *)IdentityNum{
// Preregular matching
//......
// Calculate the last 1 Bit remainder
NSArray *arrExp = [NSArray arrayWithObjects:@"7", @"9", @"10", @"5", @"8", @"4", @"2", @"1", @"6", @"3", @"7", @"9", @"10", @"5", @"8", @"4", @"2", nil];
NSArray *arrVaild = [NSArray arrayWithObjects:@"1", @"0", @"X", @"9", @"8", @"7", @"6", @"5", @"4", @"3", @"2", nil];
long sum = 0;
for (int i = 0; i < (IdentityNum.length -1); i++) {
NSString * str = [IdentityNum substringWithRange:NSMakeRange(i, 1)];
sum += [str intValue] * [arrExp[i] intValue];
}
int idx = (sum % 11);
if ([arrVaild[idx] isEqualToString:[IdentityNum substringWithRange:NSMakeRange(IdentityNum.length - 1, 1)]]) {
return YES;
}else{
return NO;
}
return YES;
}3. Mailbox Verification
/**
* Verify mailbox
*
* @param email Mailbox string
*
* @return Mailbox or not
*
* [A-Z0-9a-z] Denote A-Z And 0-9 And a-z Arbitrary 1 A
* {2,4} Denote Character bits greater than 2 A, less than 4 A
*/
+ (BOOL) validateEmail:(NSString *)email
{
NSString *emailRegex = @"[A-Z0-9a-z._%+-]+@[A-Za-z0-9.-]+\\.[A-Za-z]{2,4}";
NSPredicate *emailTest = [NSPredicate predicateWithFormat:@"SELF MATCHES %@", emailRegex];
return [emailTest evaluateWithObject:email];
}4. User name verification
/**
* User name authentication
*
* @param NSString User name string
*
* @return User name or not
* {6,20} 6 To 20 Bit
*/
+ (BOOL) validateUserName:(NSString *)name
{
NSString *userNameRegex = @"^[A-Za-z0-9]{6,20}+$";
NSPredicate *userNamePredicate = [NSPredicate predicateWithFormat:@"SELF MATCHES %@",userNameRegex];
BOOL B = [userNamePredicate evaluateWithObject:name];
return B;
}5. Password authentication
/**
* Password authentication
*
* @param NSString Password string
*
* @return Password or not
* {6,20} 6 To 20 Bit
*/
+ (BOOL) validatePassword:(NSString *)passWord
{
NSString *passWordRegex = @"^[a-zA-Z0-9]{6,20}+$";
NSPredicate *passWordPredicate = [NSPredicate predicateWithFormat:@"SELF MATCHES %@",passWordRegex];
return [passWordPredicate evaluateWithObject:passWord];
}6. Verify the nickname
/**
* Validate nicknames
*
* @param NSString Nickname string
*
* @return Nickname or not
* {4,8} 4 To 8 Bit
*/
+ (BOOL) validateNickname:(NSString *)nickname
{
NSString *nicknameRegex = @"^[\u4e00-\u9fa5]{4,8}$";
NSPredicate *passWordPredicate = [NSPredicate predicateWithFormat:@"SELF MATCHES %@",nicknameRegex];
return [passWordPredicate evaluateWithObject:nickname];
}6, 4-bit verification code verification
/**
* 4 Bit verification code
*
* @param verifyCode Verification code
*
* @return Is it a verification code
*/
+ (BOOL) validateVerifyCode:(NSString *)verifyCode
{
BOOL flag;
if (verifyCode.length <= 0) {
flag = NO;
return flag;
}
NSString *regex2 = @"^(\\d{4})$";
NSPredicate *verifyCodePredicate = [NSPredicate predicateWithFormat:@"SELF MATCHES %@",regex2];
return [verifyCodePredicate evaluateWithObject:verifyCode];
}
