IOS开发之由身份证号码提取性别的实现代码

一，代码。

- (void)viewdidload
{
[super viewdidload];
// do any additional setup after loading the view.
nsstring *sex=[self sexstrfromidentitycard:@"139876456767892345"];
nslog(@"--sex--%@",sex);
}
//由身份证号返回为性别
-(nsstring *)sexstrfromidentitycard:(nsstring *)numberstr{
nsstring *result = nil;
bool isallnumber = yes;
if([numberstr length]<17)
return result;
//**截取第17为性别识别符
nsstring *fontnumer = [numberstr substringwithrange:nsmakerange(16, 1)];
//**检测是否是数字;
const char *str = [fontnumer utf8string];
const char *p = str;
while (*p!='\0') {
if(!(*p>='0'&&*p<='9'))
isallnumber = no;
p++;
}
if(!isallnumber)
return result;
int sexnumber = [fontnumer integervalue];
if(sexnumber%2==1)
result = @"男";
///result = @"m";
else if (sexnumber%2==0)
result = @"女";
//result = @"f";
return result;
}

二，输出。
