iOS开发常用校验

一、身份证号码校验

 + (BOOL)cheakIdentityCard: (NSString *)value
 {
     value = [value stringByTrimmingCharactersInSet:[NSCharacterSet whitespaceAndNewlineCharacterSet]];
     if ([value length] != ) {
         return NO;
     }

     NSString *mmdd = @"(((0[13578]|1[02])(0[1-9]|[12][0-9]|3[01]))|((0[469]|11)(0[1-9]|[12][0-9]|30))|(02(0[1-9]|[1][0-9]|2[0-8])))";
     NSString *leapMmdd = @"";
     NSString *year = @"(19|20)[0-9]{2}";
     NSString *leapYear = @"(19|20)(0[48]|[2468][048]|[13579][26])";
     NSString *yearMmdd = [NSString stringWithFormat:@"%@%@", year, mmdd];
     NSString *leapyearMmdd = [NSString stringWithFormat:@"%@%@", leapYear, leapMmdd];
     NSString *yyyyMmdd = [NSString stringWithFormat:@"((%@)|(%@)|(%@))", yearMmdd, leapyearMmdd, @""];
     NSString *area = @"(1[1-5]|2[1-3]|3[1-7]|4[1-6]|5[0-4]|6[1-5]|82|[7-9]1)[0-9]{4}";
     NSString *regex = [NSString stringWithFormat:@"%@%@%@", area, yyyyMmdd  , @"[0-9]{3}[0-9Xx]"];
     NSPredicate *regexTest = [NSPredicate predicateWithFormat:@"SELF MATCHES %@", regex];
     if (![regexTest evaluateWithObject:value]) {
         return NO;
     }

     int summary = ([value substringWithRange:NSMakeRange(,)].intValue +
     [value substringWithRange:NSMakeRange(,)].intValue) * +
     ([value substringWithRange:NSMakeRange(,)].intValue +
     [value substringWithRange:NSMakeRange(,)].intValue) * +
     ([value substringWithRange:NSMakeRange(,)].intValue +
     [value substringWithRange:NSMakeRange(,)].intValue) * +
     ([value substringWithRange:NSMakeRange(,)].intValue +
     [value substringWithRange:NSMakeRange(,)].intValue) * +
     ([value substringWithRange:NSMakeRange(,)].intValue +
     [value substringWithRange:NSMakeRange(,)].intValue) * +
     ([value substringWithRange:NSMakeRange(,)].intValue +
     [value substringWithRange:NSMakeRange(,)].intValue) * +
     ([value substringWithRange:NSMakeRange(,)].intValue +
     [value substringWithRange:NSMakeRange(,)].intValue) * +
     [value substringWithRange:NSMakeRange(,)].intValue * +
     [value substringWithRange:NSMakeRange(,)].intValue * +
     [value substringWithRange:NSMakeRange(,)].intValue *;

     NSInteger remainder = summary % ;
     NSString *checkBit = @"";
     NSString *checkString = @"10X98765432";
     checkBit = [checkString substringWithRange:NSMakeRange(remainder,)];// 判断校验位
     return [checkBit isEqualToString:[[value substringWithRange:NSMakeRange(,)] uppercaseString]];

 }

二、手机号校验

 + (BOOL)checkTelNumber:(NSString *) telNumber
 {
     NSString *pattern = @"^1+[3578]+\d{9}";

     NSPredicate *pred = [NSPredicate predicateWithFormat:@"SELF MATCHES %@", pattern];
     BOOL isMatch = [pred evaluateWithObject:telNumber];
     return isMatch;
 }

三、简单密码校验(6-18位数字和字母组合，第一位不能是数字开头)

 + (BOOL)checkPassword:(NSString *) password
 {
     NSString *pattern = @"^(?![0-9]+$)(?![a-zA-Z]+$)[a-zA-Z0-9]{6,18}";
     NSPredicate *pred = [NSPredicate predicateWithFormat:@"SELF MATCHES %@", pattern];
     BOOL isMatch = [pred evaluateWithObject:password];
     return isMatch;
 }

四、用户姓名校验(20位的中文或英文)

 + (BOOL)checkUserName : (NSString *) userName
 {
     NSString *pattern = @"^[a-zA-Z一-龥]{1,20}";
     NSPredicate *pred = [NSPredicate predicateWithFormat:@"SELF MATCHES %@", pattern];
     BOOL isMatch = [pred evaluateWithObject:userName];
     return isMatch;
 }

五、用户邮箱校验

 + (BOOL) checkUserEmail:(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];
 }
