1、验证身份证号
+(BOOL)verifyIDnumber:(NSString *)IDnumber{
if (IDnumber.length != 18) return NO;
// 正则表达式判断基本 身份证号是否满足格式
NSString *regex2 = @"^(^[1-9]\\d{7}((0\\d)|(1[0-2]))(([0|1|2]\\d)|3[0-1])\\d{3}$)|(^[1-9]\\d{5}[1-9]\\d{3}((0\\d)|(1[0-2]))(([0|1|2]\\d)|3[0-1])((\\d{4})|\\d{3}[Xx])$)$";
NSPredicate *identityStringPredicate = [NSPredicate predicateWithFormat:@"SELF MATCHES %@",regex2];
//如果通过该验证，说明身份证格式正确，但准确性还需计算
if(![identityStringPredicate evaluateWithObject:IDnumber]) return NO;
//** 开始进行校验 *//
//将前17位加权因子保存在数组里
NSArray *idCardWiArray = @[@"7", @"9", @"10", @"5", @"8", @"4", @"2", @"1", @"6", @"3", @"7", @"9", @"10", @"5", @"8", @"4", @"2"];
//这是除以11后，可能产生的11位余数、验证码，也保存成数组
NSArray *idCardYArray = @[@"1", @"0", @"10", @"9", @"8", @"7", @"6", @"5", @"4", @"3", @"2"];
//用来保存前17位各自乖以加权因子后的总和
NSInteger idCardWiSum = 0;
for(int i = 0;i < 17;i++) {
NSInteger subStrIndex = [[IDnumber substringWithRange:NSMakeRange(i, 1)] integerValue];
NSInteger idCardWiIndex = [[idCardWiArray objectAtIndex:i] integerValue];
idCardWiSum+= subStrIndex * idCardWiIndex;
}
//计算出校验码所在数组的位置
NSInteger idCardMod=idCardWiSum%11;
//得到最后一位身份证号码
NSString *idCardLast= [IDnumber substringWithRange:NSMakeRange(17, 1)];
//如果等于2，则说明校验码是10，身份证号码最后一位应该是X
if(idCardMod==2) {
if(![idCardLast isEqualToString:@"X"]||[idCardLast isEqualToString:@"x"]) {
return NO;
}
}
else{
//用计算出的验证码与最后一位身份证号码匹配，如果一致，说明通过，否则是无效的身份证号码
if(![idCardLast isEqualToString: [idCardYArray objectAtIndex:idCardMod]]) {
return NO;
}
}
return YES;
}
2、验证手机号
+ (BOOL)valiMobile:(NSString *)mobile{
mobile = [mobile stringByReplacingOccurrencesOfString:@" " withString:@""];
if (mobile.length != 11)
{
return NO;
}else{
/**
* 移动号段正则表达式
*/
NSString *CM_NUM = @"^((13[4-9])|(147)|(15[0-2,7-9])|(178)|(18[2-4,7-8]))\\d{8}|(1705)\\d{7}$";
/**
* 联通号段正则表达式
*/
NSString *CU_NUM = @"^((13[0-2])|(145)|(15[5-6])|(176)|(18[5,6]))\\d{8}|(1709)\\d{7}$";
/**
* 电信号段正则表达式
*/
NSString *CT_NUM = @"^((133)|(153)|(177)|(18[0,1,9]))\\d{8}$";
NSPredicate *pred1 = [NSPredicate predicateWithFormat:@"SELF MATCHES %@", CM_NUM];
BOOL isMatch1 = [pred1 evaluateWithObject:mobile];
NSPredicate *pred2 = [NSPredicate predicateWithFormat:@"SELF MATCHES %@", CU_NUM];
BOOL isMatch2 = [pred2 evaluateWithObject:mobile];
NSPredicate *pred3 = [NSPredicate predicateWithFormat:@"SELF MATCHES %@", CT_NUM];
BOOL isMatch3 = [pred3 evaluateWithObject:mobile];
if (isMatch1 || isMatch2 || isMatch3) {
return YES;
}else{
return NO;
}
}
}
3、根据银行卡号返回银行卡名称
- (NSString *)returnBankName:(NSString*) idCard{
NSString *plistPath = [[NSBundle mainBundle] pathForResource:@"bank" ofType:@"plist"];
NSDictionary* resultDic = [NSDictionary dictionaryWithContentsOfFile:plistPath];
NSArray *bankName = [resultDic objectForKey:@"bankName"];
NSArray *bankBin = [resultDic objectForKey:@"bankBin"];
int index = -1;
if(idCard==nil || idCard.length<16 || idCard.length>19){
return @"";
}
//6位Bin号
NSString* cardbin_6 = [idCard substringWithRange:NSMakeRange(0, 6)];
for (int i = 0; i < bankBin.count; i++) {
if ([cardbin_6 isEqualToString:bankBin[i]]) {
index = i;
}
}
if (index != -1) {
return bankName[index];
}
//8位Bin号
NSString* cardbin_8 = [idCard substringWithRange:NSMakeRange(0, 8)];
for (int i = 0; i < bankBin.count; i++) {
if ([cardbin_8 isEqualToString:bankBin[i]]) {
index = i;
}
}
if (index != -1) {
return bankName[index];
}
return @"";
}
