实现简单通讯录操作。 1、定义联系人类AddressPerson。实例变量：姓名、性别、电话号码、住址、分组名称。方法：自定义初始化方法（姓名、电话号码）、显示联系人信息 2、在main.m中定义可变

(在 .h文件中声明)
#import 

@interface AddressPerson : NSObject
{
    NSString *_name;//姓名
    NSString *_gender;//性别
    NSString *_number;//电话号码
    NSString *_address;//地址
    NSString *_croupName;//分组名
}
//自定义初始化
- (id)initWithName:(NSString*)name gender:(NSString*)gender number:(NSString*)number address:(NSString*)address croupName:(NSString*)croupName;
//显示联系人信息
- (void)theContactInformation;
//setter方法
- (void)setName:(NSString*)name;
//设置姓名
- (void)setGender:(NSString*)gender;
//设置性别
- (void)setNumber:(NSString*)number;
//设置电话号码
- (void)setAddress:(NSString*)address;
//设置地址
- (void)setCroupName:(NSString*)croupName;
//设置分组名

//getter方法
- (NSString*)name;
- (NSString*)gender;
- (NSString*)number;
- (NSString*)address;
- (NSString*)croupName;
@end

(在 .m 文件中 实现)
#import "AddressPerson.h"

@implementation AddressPerson
//自定义初始化
- (id)initWithName:(NSString*)name gender:(NSString*)gender number:(NSString*)number address:(NSString*)address croupName:(NSString*)croupName
{
    self = [super init];
    if (self != nil) {
        _name = name;
        _gender = gender;
        _number = number;
        _address = address;
        _croupName = croupName;
    }
    return self;
}
//显示联系人信息
- (void)theContactInformation
{
    NSLog(@"name:%@,gender:%@,number:%@,address:%@,%@",_name, _gender, _number, _address, _croupName);
}


//setter方法
- (void)setName:(NSString*)name
{
    _name = name;
}
//设置姓名
- (void)setGender:(NSString*)gender
{
    _gender = gender;
}
//设置性别
- (void)setNumber:(NSString*)number
{
    _number = number;
}
//设置电话号码
- (void)setAddress:(NSString*)address
{
    _address = address;
}
//设置地址
- (void)setCroupName:(NSString*)croupName
{
    _croupName = croupName;
}
//设置分组名

//getter方法
- (NSString*)name
{
    return _name;
}
- (NSString*)gender
{
    return _gender;
}
- (NSString*)number
{
    return _number;
}
- (NSString*)address
{
    return _address;
}
- (NSString*)croupName
{
    return _croupName;
}
