1、手机号码的验证正则
正则表达式：
^((13[0-9])|(15[^4,\D])|(18[0,0-9]))\d{8}$
详细解释
解释：
•^...$:
^:开始
$:结束
中间为要处理的字串
•(13[0-9]): 以13开头接下来一位为0-9之间的数
13 : 以13开头
[0-9]:分割语法,13后面是0-9之间的数
•| : 或(or), 将前后两个匹配条件进行or运算
• (15[^4\D]) : 以15开头接下来一位是除4之外的0-9数字
15 : 以15开头
[^4\D] : 除了4之外的所有0-9的数字
^:此处为非 ^4 为除4之外的任何字符
D: D为非数字 ``为转义字符
•(18[0,2,5-9]) : 以18开头接下来一位为0或者2或者5-9之间的数
•d{8} : 8个0-9的数字
d:0-9之间的数字
{8} : 匹配8次
正则表达式的使用：
+ (BOOL)isMobileNumber:(NSString *)mobileNumber
{
//手机号以13， 15，18开头，八个 d 数字字符
NSString *phoneRegex = @"^((13[0-9])|(15[^4,\D])|(18[0,0-9]))\d{8}$";
NSPredicate *phoneTest = [NSPredicate predicateWithFormat:@"SELF MATCHES %@",phoneRegex];
return [phoneTest evaluateWithObject:mobileNumber];
}
2、身份证验证
+ (BOOL) validateIdentityCard: (NSString *)identityCard
{
BOOL flag;
if (identityCard.length <= 0) {
flag = NO;
return flag;
}
NSString *regex2 = @"^(\d{14}|\d{17})(\d|[xX])$";
NSPredicate *identityCardPredicate = [NSPredicate predicateWithFormat:@"SELF MATCHES %@",regex2];
return [identityCardPredicate evaluateWithObject:identityCard];
}
+(BOOL)isValidWithIdentityNum:(NSString *)IdentityNum{
//先正则匹配
//......
//计算最后一位余数
NSArray *arrExp = [NSArray arrayWithObjects:@"7", @"9", @"10", @"5", @"8", @"4", @"2", @"1", @"6", @"3", @"7", @"9", @"10", @"5", @"8", @"4", @"2", nil];
NSArray *arrVaild = [NSArray arrayWithObjects:@"1", @"0", @"X", @"9", @"8", @"7", @"6", @"5", @"4", @"3", @"2", nil];
long sum = 0;
for (int i = 0; i < (IdentityNum.length -1); i++) {
NSString * str = [IdentityNum substringWithRange:NSMakeRange(i, 1)];
sum += [str intValue] * [arrExp[i] intValue];
}
int idx = (sum % 11);
if ([arrVaild[idx] isEqualToString:[IdentityNum substringWithRange:NSMakeRange(IdentityNum.length - 1, 1)]]) {
return YES;
}else{
return NO;
}
return YES;
}
3、邮箱验证
+ (BOOL) validateEmail:(NSString *)email
{
NSString *emailRegex = @"[A-Z0-9a-z._%+-]+@[A-Za-z0-9.-]+\.[A-Za-z]{2,4}";
NSPredicate *emailTest = [NSPredicate predicateWithFormat:@"SELF MATCHES %@", emailRegex];
return [emailTest evaluateWithObject:email];
}
4、用户名验证
+ (BOOL) validateUserName:(NSString *)name
{
NSString *userNameRegex = @"^[A-Za-z0-9]{6,20}+$";
NSPredicate *userNamePredicate = [NSPredicate predicateWithFormat:@"SELF MATCHES %@",userNameRegex];
BOOL B = [userNamePredicate evaluateWithObject:name];
return B;
}
5、密码认证
+ (BOOL) validatePassword:(NSString *)passWord
{
NSString *passWordRegex = @"^[a-zA-Z0-9]{6,20}+$";
NSPredicate *passWordPredicate = [NSPredicate predicateWithFormat:@"SELF MATCHES %@",passWordRegex];
return [passWordPredicate evaluateWithObject:passWord];
}
6、验证昵称
+ (BOOL) validateNickname:(NSString *)nickname
{
NSString *nicknameRegex = @"^[u4e00-u9fa5]{4,8}$";
NSPredicate *passWordPredicate = [NSPredicate predicateWithFormat:@"SELF MATCHES %@",nicknameRegex];
return [passWordPredicate evaluateWithObject:nickname];
}
6、4位验证码验证
+ (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];
}
