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:@"" sex:@"m" age:];
Person *p2 = [Person personWithName:@"Joe" phoneNum:@"" sex:@"m" age:];
Person *p3 = [Person personWithName:@"Kitty" phoneNum:@"" sex:@"n" age:];
Person *p5 = [Person personWithName:@"Andy" phoneNum:@"" sex:@"n" age:]; 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:@""];
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:@"" sex:@"n" age:];
NSLog(@"%d",bb); NSLog(@"%@",a.addressBook); [a showAll];
[a autorelease];
} return ;
}
二、Person.h
#import <Foundation/Foundation.h> @interface Person : NSObject

@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

} // 重写description方法
- (NSString *)description{

}
@end
四、AddressBook.h
#import <Foundation/Foundation.h>
@class Person;
@interface AddressBook : NSObject
@property (nonatomic,retain)NSMutableDictionary *addressBook; // 获取首字母
- (NSString *)firstChar:(NSString *)str; // 添加联系人
- (BOOL)addPerson:(Person *)aPerson; // 按照姓名删除联系人
- (BOOL)deletePersonWithName:(NSString *)aPersonName; // 删除一个分组
- (BOOL)deleteGroup:(NSString *)aGroupName; // 根据电话朝找某个联系人
- (Person *)findPersonWithPhoneNum:(NSString *)aPhoneNum; // 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 *)findPersonWithSex:(NSString *)aSex; // 根据姓名,更改联系人信息
- (BOOL)changPersonWithName:(NSString *)name phoneNum:(NSString *)aNum sex:(NSString *)aSex age:(NSUInteger)aAge; // 展示所有联系人
- (void)showAll;
