经过两天的低迷，状态在慢慢的回归了，生活还要继续，人生还需奋斗！

祝：好人一生平安！！！

========================================================================

题目描述：

1.创建AddressBook类. 1)使?用字典作为容器,字典的Key值为分组名(姓名?首字?母,?大写),value值为数组,数组

姓名:Linda 性别:?女 电话:000 年龄:21 3).调?用添加联系?人?方法,将四个联系?人添加到通讯录中.? 4).根据电话查找联系?人,并打印(查找电话:456); 5).根据性别查找联系?人,并将查到的联系?人按照年龄升序排序,并打印(查找性别:?女) 6).根据姓名,更改联系?人信息.(修改Linda的信息: 性别:?女 电话:012 年龄:25); 7).按照姓名删除联系?人,并展?示通信录中所有?人信息.(删除联系?人:Baby) 8).删除?一个分组,并展?示通信录中所有?人信息.(删除L组)

</span></span>

我定义的分类是NSString+firstCapitalLetter，把这个类目当做模板来用，别的工程把该类目考入能直接用。

NSString+firstCapitalLetter.h中实现

<span style="font-size:18px;">#import <Foundation/Foundation.h>
#define ALPHA	@"ABCDEFGHIJKLMNOPQRSTUVWXYZ#"
char pinyinFirstLetter(unsigned short hanzi);
@interface NSString (firstCapitalLetter)
// 提供首字母大写
- (NSString *) uppercasePinYinFirstLetter;
- (NSString *) lowercasePinYinFirstLetter;
@end</span>

#import "NSString+firstCapitalLetter.h"

#define HANZI_START 19968
#define HANZI_COUNT 20902
static char firstLetterArray[HANZI_COUNT] =
"ydkqsxnwzssxjbymgcczqpssqbycdscdqldylybssjgyqzjjfgcclzznwdwzjljpfyynnjjtmynzwzhflzppqhgccyynmjqyxxgd"；

char pinyinFirstLetter(unsigned short hanzi)
{
	int index = hanzi - HANZI_START;
	if (index >= 0 && index <= HANZI_COUNT)
	{
		return firstLetterArray[index];
	}
	else
	{
		return hanzi;
	}
}

@implementation NSString(firstCapitalLetter)

- (NSString *) uppercasePinYinFirstLetter
{
    unichar firstLetter = [self characterAtIndex:0];
    char cFirstLetter = pinyinFirstLetter(firstLetter);
    return [[NSString stringWithFormat:@"%c",cFirstLetter] uppercaseString];
}
- (NSString *) lowercasePinYinFirstLetter
{
    unichar firstLetter = [self characterAtIndex:0];
    char cFirstLetter = pinyinFirstLetter(firstLetter);
    return [[NSString stringWithFormat:@"%c",cFirstLetter] lowercaseString];
}

@end

模板用就行

<span style="font-size:14px;">@property(nonatomic,copy)NSString * name;
@property(nonatomic,assign)NSInteger age;
@property(nonatomic,copy) NSString * sex;
@property(nonatomic,copy)NSString * phone;
@property(nonatomic,copy)NSString * group;

// person的便利构造器
+ (instancetype)personWithName:(NSString *)name
                           age:(NSInteger)age
                           sex:(NSString *)sex
                         phone:(NSString *)phone;

- (instancetype)initWithName:(NSString *)name age:(NSInteger)age sex:(NSString *)sex phone:(NSString *)phone;</span>

Person.m

- (void)setName:(NSString *)name
{
    if (_name != name) {
        [_name release];
        _name = [name copy];
    }
    self.group = [name uppercasePinYinFirstLetter];

}

- (NSString *)description
{
    return [NSString stringWithFormat:@"name=%@,age=%ld,sex=%@,phone=%@",_name,_age,_sex,_phone];
}
//
+ (instancetype)personWithName:(NSString *)name
                           age:(NSInteger)age
                           sex:(NSString *)sex
                         phone:(NSString *)phone
{
    Person * per = [[Person alloc]initWithName:name age:age sex:sex phone:phone];
    return [per autorelease];
    
}

//
- (instancetype)initWithName:(NSString *)name age:(NSInteger)age sex:(NSString *)sex phone:(NSString *)phone
{
    if (self = [super init]) {
        self.name  = name;
        self.age   = age;
        self.sex   = sex;
        self.phone = phone;
        //=================
        self.group = [name uppercasePinYinFirstLetter];
    }
    return self;
    
}

// 此句只能给AddressBook中的dic分配了一个指针的空间大小
    AddressBook * addressBook = [[AddressBook alloc]init];
    // 单独给NSMutableDictionary类型的dic分配空间
    // 如果不使用AddressBook.m的init方法则用这一句就可以替代它
    addressBook.dic = [[NSMutableDictionary alloc] init];
   
    
    Person * per1 = [Person personWithName:@"Lucy" age:21 sex:@"女" phone:@"123"];
    Person * per2 = [Person personWithName:@"Joe" age:17 sex:@"男" phone:@"456"];

    Person * per3 = [Person personWithName:@"Baby" age:27 sex:@"女" phone:@"789"];
    
    Person * per4 = [Person personWithName:@"Linda" age:21 sex:@"女" phone:@"000"];
    //========================
    [addressBook addPerson:per1];
    [addressBook addPerson:per2];
    [addressBook addPerson:per3];
    [addressBook addPerson:per4];
    [addressBook showAll];
    //========================
    Person * p = [addressBook findPersonWithPhoneNum:@"456"];
    if (!p) {
        NSLog(@"NULL!");
    }
    else{
    NSLog(@"%@",p);
    }
     //========================
    
    NSArray * arr = [addressBook findPersonsWithSex:@"女"];
    NSLog(@"%@",arr);
    //========================
    [addressBook changePersonWithName:@"Linda" phone:@"012" sex:@"女" age:25];
    NSLog(@"%@",[addressBook selectPersonWithName:@"Linda"]);
    //========================
    [addressBook deletePersonWithName:@"Baby"];
    [addressBook showAll];
//    //========================
    [addressBook deleteGroup:@"L"];
    [addressBook showAll];[addressBook showAll];

人活在世，不仅仅为了自己，更多的是不要让那些关心你的人失望！！！！
