先建立AddressContact类,在AddressContact类的.h文件中,写如下代码:
@interface AddressContact : NSObject
{
    NSString *_name;//姓名
    NSString *_gender;//性别
    NSInteger _age;//年龄
    NSString * _number;//电话号码
    NSString *_address;//地址
    NSString *_namePacket;//分组名称
}
//自定义初始化方法
- (id) initWithName:(NSString *)name gender:(NSString *)gender  age:(NSInteger)age number:(NSString *)number address:(NSString *)address namePacket:(NSString *)namePacket;
//setter
- (void)setName:(NSString *)name;
- (void)setGender:(NSString *)gender;
- (void)setAge:(NSInteger)age;
- (void)setNumber:(NSString *)number;
- (void)setAddress:(NSString *)address;
- (void)setNamePacket:(NSString *)namePacket;
//getter
- (NSString *)name;
- (NSString *)gender;
- (NSInteger)age;
- (NSString *)number;
- (NSString *)address;
- (NSString *)namePacket;
//重写从父类继承过来的description方法(显示联系人信息)
- (NSString *)description;
//按姓名升序排序
- (NSComparisonResult)sortName:(AddressContact *)aName;
//按年龄降序排序
- (NSComparisonResult)sortAge:(AddressContact *)aAge;
@end

在AddressContact类的.m文件中写如下代码:

@implementation AddressContact
//自定义初始化方法
- (id) initWithName:(NSString *)name gender:(NSString *)gender age:(NSInteger)age number:(NSString *)number address:(NSString *)address namePacket:(NSString *)namePacket
{
    self = [super init];
    if (self != nil) {
        _name = name;
        _gender = gender;
        _age = age;
        _number = number;
        _address = address;
        _namePacket = namePacket;
    }
    return self;
}
//setter
- (void)setName:(NSString *)name
{
    _name = name;
}
- (void)setGender:(NSString *)gender
{
    _gender = gender;
}
- (void)setAge:(NSInteger)age
{
    _age = age;
}
- (void)setNumber:(NSString *)number
{
    _number = number;
}
- (void)setAddress:(NSString *)address
{
    _address = address;
}
- (void)setNamePacket:(NSString *)namePacket
{
    _namePacket = namePacket;
}
//getter
- (NSString *)name
{
    return _name;
}
- (NSString *)gender
{
    return _gender;
}
- (NSInteger)age
{
    return _age;
}
- (NSString *)number
{
    return  _number;
}
- (NSString *)address
{
    return  _address;
}
- (NSString *)namePacket
{
    return _namePacket;
}
//重写从父类继承过来的description方法(显示联系人信息)
- (NSString *)description
{
    return [NSString stringWithFormat:@"%@   %@   %ld   %@   %@   %@ ",_name,_gender,_age,_number,_address,_namePacket];
}
//按姓名升序排序
- (NSComparisonResult)sortName:(AddressContact *)aName
{
    return [[self name] compare:[aName name]];
}
//按年龄降序排序
- (NSComparisonResult)sortAge:(AddressContact *)aAge
{
    if ([self age] > [aAge age]) {
        return NSOrderedAscending;
    }else if ([self age] == [aAge age]){
        return NSOrderedSame;
    }else{
        return NSOrderedDescending;
    }
    
}
@end
在main.m的文件中创建对象,并写如下代码:

        //创建对象
        AddressContact *person1 = [[AddressContact alloc] initWithName:@"Xiaoxiao" gender:@"m" age:21 number:@"18536968954" address:@"河南郑州" namePacket:@"X"];
        AddressContact *person2 = [[AddressContact alloc] initWithName:@"Daxiao" gender:@"m" age:29 number:@"18536969954" address:@"河南郑州" namePacket:@"D"];
        AddressContact *person3 = [[AddressContact alloc] initWithName:@"Wangda" gender:@"f" age:23 number:@"18536964554" address:@"北京市" namePacket:@"W"];
        AddressContact *person4 = [[AddressContact alloc] initWithName:@"Xiaoyu" gender:@"f" age:12 number:@"18126968954" address:@"河南郑州" namePacket:@"X"];
        AddressContact *person5 = [[AddressContact alloc] initWithName:@"Wanyu" gender:@"m" age:32 number:@"18536961234" address:@"上海市" namePacket:@"W"];
        AddressContact *person6 = [[AddressContact alloc] initWithName:@"Dangho" gender:@"f" age:16 number:@"18536968954" address:@"河南郑州" namePacket:@"D"];

        AddressContact *person8 = [[AddressContact alloc] initWithName:@"Wangxiao" gender:@"m" age:36 number:@"18536965436" address:@"郑州" namePacket:@"W"];
        AddressContact *person9 = [[AddressContact alloc] initWithName:@"Aoxiao" gender:@"m" age:23 number:@"23536968954" address:@"河南郑州" namePacket:@"A"];
        AddressContact *person10 = [[AddressContact alloc] initWithName:@"Aanda" gender:@"f" age:25 number:@"18565768954" address:@"河南郑州" namePacket:@"A"];
        NSMutableArray *arr1 = [NSMutableArray arrayWithObjects:person1,person4, nil];
        NSMutableArray *arr2 = [NSMutableArray arrayWithObjects:person2,person6, nil];
        NSMutableArray *arr3 = [NSMutableArray arrayWithObjects:person3,person5,person8, nil];
        NSMutableArray *arr4 = [NSMutableArray arrayWithObjects:person7,person9,person10, nil];
        NSMutableDictionary *dic = [NSMutableDictionary dictionaryWithObjectsAndKeys:arr1,@"X",arr2,@"D",arr3,@"W",arr4,@"A", nil];
        
//添加联系人
        AddressContact *person11 = [[AddressContact alloc] initWithName:@"Bada" gender:@"f" age:39 number:@"18565766544" address:@"河南郑州" namePacket:@"A"];
        NSMutableArray *Arr = [[NSMutableArray alloc] init];
        if ([[person11 name] isEqualToString:@"" ]||[[person11 number] isEqualToString:@""] ) {
            NSLog(@"添加失败");
        }else{
            NSString *str = [[person11 name] substringWithRange:NSMakeRange(0, 1)];//获取联系人姓名首字母
      for (NSString *key in dic) {
            if ([key isEqualToString:str]) {
                [[dic objectForKey:key] addObject:person11];
