OC-通讯录

要求描述:用OC语言完成简易通讯录(实现增删改查)功能.(注:使用MRC)

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),value值为数组,数组中存放联系人(Person实例).(5分)

2)添加联系人.要求(20分)

a.判断姓名和电话不能为空否则添加失败.

b.判断是否已经存在分组,存在直接存储.不存在创建分组后再存储.(注:不能有 重名).

c.添加成功返回YES,姓名为空或者有重名的添加失败返回NO. d.数据使用Person存储.

e.方法:- (BOOL)addPerson:(Person *)aPerson;

3)按照姓名删除联系人.(15分)

a.方法:- (BOOL)deletePersonWithName:(NSString*)aPersonName; b.删除成功返回YES,否则返回NO;

4)删除一个分组.(10分)

a:方法:- (BOOL)deleteGroup:(NSString *)aGroupName;

b.删除成功返回YES,否则返回NO;

5)根据电话查找某个联系人.(10分)

a:方法:-(Person *)findPersonWithPhoneNum:(NSString *)aPhoneNum;

b:如果找到返回该联系人,否则返回nil.

6)根据性别查找联系人,并将查到的联系人按照姓名排序(15分) a:方法:-(NSArray *)findPersonsWithSex:(NSString *)aSex; b:查找到联系人放入数组,排序的时候使用block.

7)根据姓名,更改联系人信息.(10分)

a:方法:-(BOOL)changePersonWithName:(NSString *)name phoneNum:(NSString *)aNum sex:(NSString *)aSex age:(NSUInteger) aAge; b:找到该联系人并修改该成功返回YES,否则返回NO

8)展示通讯录中的所有联系人(5分)

a:方法:-(void)showAll;

2.使用Person类.(属性:姓名,年龄,性别,电话)

1)重写description方法.(5分)

2)使用便利构造器.(5分)

一、main.m

#import <Foundation/Foundation.h>
#import "Person.h"
#import "AddressBook.h"
int main(int argc, const char * argv[]) {

    @autoreleasepool {
        
    
        Person *p1 = [Person personWithName:@"Mike" phoneNum:@"123" sex:@"m" age:12];
        Person *p2 = [Person personWithName:@"Joe" phoneNum:@"234" sex:@"m" age:13];
        Person *p3 = [Person personWithName:@"Kitty" phoneNum:@"345" sex:@"n" age:15];
        Person *p5 = [Person personWithName:@"Andy" phoneNum:@"456" sex:@"n" age:15];
    
    AddressBook *a = [[AddressBook alloc] init];
    // 添加联系人
    BOOL b1 = [a addPerson:p1];
    BOOL b2 = [a addPerson:p2];
    BOOL b3 = [a addPerson:p3];
    BOOL b6 = [a addPerson:p5];
    NSLog(@"%d %d %d %d",b1,b2,b3,b6);
        [a showAll];
    // 按照姓名删除联系人
    BOOL b4 = [a deletePersonWithName:@"Mike"];
    NSLog(@"%d",b4);
    // 删除一个分组
    BOOL b5 = [a deleteGroup:@"J"];
    NSLog(@"%d",b5);
    // 根据电话查找某个联系人
    Person *p4 = [a findPersonWithPhoneNum:@"345"];
    NSLog(@"%@",p4);
    // 根据性别查找某个联系人,并将查到的联系人按照姓名排序
    NSArray *arr = [a findPersonWithSex:@"n"];
    for (Person *tempPerson in arr) {
        NSLog(@"----%@",tempPerson);
    }
    // 根据姓名,更改联系人信息
    BOOL bb = [a changPersonWithName:@"Kitty" phoneNum:@"123" sex:@"n" age:15];
    NSLog(@"%d",bb);
    
    NSLog(@"%@",a.addressBook);
    
    [a showAll];
    [a autorelease];
    }

    return 0;
}

二、Person.h

#import <Foundation/Foundation.h>

@interface Person : NSObject
@property (nonatomic,copy)NSString *name;
@property (nonatomic,copy)NSString *phoneNum;
@property (nonatomic,copy)NSString *sex;
@property (nonatomic,assign)NSUInteger age;

// 初始化方法
- (instancetype)initWithName:(NSString *)name phoneNum:(NSString *)aNum sex:(NSString *)aSex age:(NSUInteger)aAge;
// 便利构造器
+ (instancetype)personWithName:(NSString *)name phoneNum:(NSString *)aNum sex:(NSString *)aSex age:(NSUInteger)aAge;

@end

三、Person.m

#import "Person.h"

@implementation Person

// 初始化方法
- (instancetype)initWithName:(NSString *)name phoneNum:(NSString *)aNum sex:(NSString *)aSex age:(NSUInteger)aAge{
    
    if (self = [super init]) {
        self.name = name;
        self.phoneNum = aNum;
        self.sex = aSex;
        self.age = aAge;
    }
    return self;
}
// 便利构造器
+ (instancetype)personWithName:(NSString *)name phoneNum:(NSString *)aNum sex:(NSString *)aSex age:(NSUInteger)aAge{
    
    Person *p = [[Person alloc] initWithName:name phoneNum:aNum sex:aSex age:aAge];
    return [p autorelease];
}

// 重写description方法
- (NSString *)description{
    return [NSString stringWithFormat:@"Name:%@ phoneNum:%@ sex:%@ age:%ld",self.name,self.phoneNum,self.sex,self.age];
}
@end
