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;

									}
