iOS开发常用校验

一、身份证号码校验

 1 + (BOOL)cheakIdentityCard: (NSString *)value
 2 {
 3     value = [value stringByTrimmingCharactersInSet:[NSCharacterSet whitespaceAndNewlineCharacterSet]];
 4     if ([value length] != 18) {
 5         return NO;
 6     }
 7     
 8     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])))";
 9     NSString *leapMmdd = @"0229";
10     NSString *year = @"(19|20)[0-9]{2}";
11     NSString *leapYear = @"(19|20)(0[48]|[2468][048]|[13579][26])";
12     NSString *yearMmdd = [NSString stringWithFormat:@"%@%@", year, mmdd];
13     NSString *leapyearMmdd = [NSString stringWithFormat:@"%@%@", leapYear, leapMmdd];
14     NSString *yyyyMmdd = [NSString stringWithFormat:@"((%@)|(%@)|(%@))", yearMmdd, leapyearMmdd, @"20000229"];
15     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}";
16     NSString *regex = [NSString stringWithFormat:@"%@%@%@", area, yyyyMmdd  , @"[0-9]{3}[0-9Xx]"];
17     NSPredicate *regexTest = [NSPredicate predicateWithFormat:@"SELF MATCHES %@", regex];
18     if (![regexTest evaluateWithObject:value]) {
19         return NO;
20     }
21     
22     int summary = ([value substringWithRange:NSMakeRange(0,1)].intValue +
23     [value substringWithRange:NSMakeRange(10,1)].intValue) *7 +
24     ([value substringWithRange:NSMakeRange(1,1)].intValue +
25     [value substringWithRange:NSMakeRange(11,1)].intValue) *9 +
26     ([value substringWithRange:NSMakeRange(2,1)].intValue +
27     [value substringWithRange:NSMakeRange(12,1)].intValue) *10 +
28     ([value substringWithRange:NSMakeRange(3,1)].intValue +
29     [value substringWithRange:NSMakeRange(13,1)].intValue) *5 +
30     ([value substringWithRange:NSMakeRange(4,1)].intValue +
31     [value substringWithRange:NSMakeRange(14,1)].intValue) *8 +
32     ([value substringWithRange:NSMakeRange(5,1)].intValue +
33     [value substringWithRange:NSMakeRange(15,1)].intValue) *4 +
34     ([value substringWithRange:NSMakeRange(6,1)].intValue +
35     [value substringWithRange:NSMakeRange(16,1)].intValue) *2 +
36     [value substringWithRange:NSMakeRange(7,1)].intValue *1 +
37     [value substringWithRange:NSMakeRange(8,1)].intValue *6 +
38     [value substringWithRange:NSMakeRange(9,1)].intValue *3;
39     
40     NSInteger remainder = summary % 11;
41     NSString *checkBit = @"";
42     NSString *checkString = @"10X98765432";
43     checkBit = [checkString substringWithRange:NSMakeRange(remainder,1)];// 判断校验位
44     return [checkBit isEqualToString:[[value substringWithRange:NSMakeRange(17,1)] uppercaseString]];
45     
46 }

二、手机号校验

1 + (BOOL)checkTelNumber:(NSString *) telNumber
2 {
3     NSString *pattern = @"^1+[3578]+d{9}";
4 
5     NSPredicate *pred = [NSPredicate predicateWithFormat:@"SELF MATCHES %@", pattern];
6     BOOL isMatch = [pred evaluateWithObject:telNumber];
7     return isMatch;
8 }

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)

1 + (BOOL)checkPassword:(NSString *) password
2 {
3     NSString *pattern = @"^(?![0-9]+$)(?![a-zA-Z]+$)[a-zA-Z0-9]{6,18}";
4     NSPredicate *pred = [NSPredicate predicateWithFormat:@"SELF MATCHES %@", pattern];
5     BOOL isMatch = [pred evaluateWithObject:password];
6     return isMatch;
7 }

四、用户姓名校验(20位的中文或英文)

1 + (BOOL)checkUserName : (NSString *) userName
2 {
3     NSString *pattern = @"^[a-zA-Z一-龥]{1,20}";
4     NSPredicate *pred = [NSPredicate predicateWithFormat:@"SELF MATCHES %@", pattern];
5     BOOL isMatch = [pred evaluateWithObject:userName];
6     return isMatch;
7 }

五、用户邮箱校验

1 + (BOOL) checkUserEmail:(NSString *)email
2 {
3     NSString *emailRegex = @"[A-Z0-9a-z._%+-]+@[A-Za-z0-9.-]+\.[A-Za-z]{2,4}";
4     NSPredicate *emailTest = [NSPredicate predicateWithFormat:@"SELF MATCHES %@", emailRegex];
5     return [emailTest evaluateWithObject:email];
6 }
