首先在UITextField代理中
- (void)textFieldDidEndEditing:(UITextField *)textField方法里設(shè)置
- (void)textFieldDidEndEditing:(UITextField *)textField;{
if (self.IDCardNoField == textField) {
NSCharacterSet *setToRemove = [[ NSCharacterSet characterSetWithCharactersInString:@"0123456789X"]
invertedSet ];
self.IDCardNoField.text = [[self.IDCardNoField.text componentsSeparatedByCharactersInSet:setToRemove] componentsJoinedByString:@""];
}
}
這會(huì)讓你在編輯結(jié)束后將非省份證號(hào)包含的字符消除掉
判斷身份證號(hào)是否合法
百度上搜到的方法是,但判斷強(qiáng)度很雞肋
- (BOOL)isCorrect:(NSString *)IDNumber
{
NSMutableArray *IDArray = [NSMutableArray array];
// 遍歷身份證字符串,存入數(shù)組中
for (int i = 0; i < 18; i++) {
NSRange range = NSMakeRange(i, 1);
NSString *subString = [IDNumber substringWithRange:range];
[IDArray addObject:subString];
}
// 系數(shù)數(shù)組
NSArray *coefficientArray = [NSArray arrayWithObjects:@"7", @"9", @"10", @"5", @"8", @"4", @"2", @"1", @"6", @"3", @"7", @"9", @"10", @"5", @"8", @"4", @"2", nil];
// 余數(shù)數(shù)組
NSArray *remainderArray = [NSArray arrayWithObjects:@"1", @"0", @"X", @"9", @"8", @"7", @"6", @"5", @"4", @"3", @"2", nil];
// 每一位身份證號(hào)碼和對(duì)應(yīng)系數(shù)相乘之后相加所得的和
int sum = 0;
for (int i = 0; i < 17; i++) {
int coefficient = [coefficientArray[i] intValue];
int ID = [IDArray[i] intValue];
sum += coefficient * ID;
}
// 這個(gè)和除以11的余數(shù)對(duì)應(yīng)的數(shù)
NSString *str = remainderArray[(sum % 11)];
// 身份證號(hào)碼最后一位
NSString *string = [IDNumber substringFromIndex:17];
// 如果這個(gè)數(shù)字和身份證最后一位相同,則符合國家標(biāo)準(zhǔn),返回YES
if ([str isEqualToString:string]) {
return YES;
} else {
return NO;
}
}
下面附上我的方法(在原有的基礎(chǔ)上加了)
- (BOOL)isCorrect:(NSString *)IDNumber
{
if (IDNumber.length<18) {
return NO;
}
NSMutableArray *IDArray = [NSMutableArray array];
// 遍歷身份證字符串,存入數(shù)組中
for (int i = 0; i < 18; i++) {
NSRange range = NSMakeRange(i, 1);
NSString *subString = [IDNumber substringWithRange:range];
[IDArray addObject:subString];
}
// 系數(shù)數(shù)組
NSArray *coefficientArray = [NSArray arrayWithObjects:@"7", @"9", @"10", @"5", @"8", @"4", @"2", @"1", @"6", @"3", @"7", @"9", @"10", @"5", @"8", @"4", @"2", nil];
// 余數(shù)數(shù)組
NSArray *remainderArray = [NSArray arrayWithObjects:@"1", @"0", @"X", @"9", @"8", @"7", @"6", @"5", @"4", @"3", @"2", nil];
// 每一位身份證號(hào)碼和對(duì)應(yīng)系數(shù)相乘之后相加所得的和
int sum = 0;
for (int i = 0; i < 17; i++) {
int coefficient = [coefficientArray[i] intValue];
int ID = [IDArray[i] intValue];
sum += coefficient * ID;
}
// 這個(gè)和除以11的余數(shù)對(duì)應(yīng)的數(shù)
NSString *str = remainderArray[(sum % 11)];
// 身份證號(hào)碼最后一位
NSString *string = [IDNumber substringFromIndex:17];
// 如果這個(gè)數(shù)字和身份證最后一位相同,則符合國家標(biāo)準(zhǔn),返回YES
if ([str isEqualToString:string]) {
NSString *birthdayYer = [IDNumber substringWithRange:NSMakeRange(6, 4)];
NSString *birthdayMan = [IDNumber substringWithRange:NSMakeRange(10, 2)];
NSString *birthdayDay = [IDNumber substringWithRange:NSMakeRange(12, 2)];
if ([birthdayYer intValue]<1900||[birthdayMan intValue]==0||[birthdayMan intValue]>12||[birthdayDay intValue]==1||[birthdayDay intValue]>31) {
return NO;
}
return YES;
} else {
return NO;
}
}
秸脱！注意！注意！注意杨蛋！注意（正確返回YES）
如果提交表單時(shí)檢驗(yàn) 帖下面代碼
if (![self checkCardNo:self.IDCardNoField.text]) {
[self showHudStringAlert:@"請(qǐng)輸入正確銀行卡號(hào)"];
return;
}
謝謝倍靡！
