-(id)initwithcoder:(nscoder *)coder;

-(void)encodewithcoder:(nscoder *)coder;

//

caretaker : nsobject


@property(nonatomic,strong) memo *memo;


@end
caretaker.m

//


// caretaker.m


// memodemo


//// created by zhanggui on 15/8/8.


//#import "caretaker.h"


@implementation


caretaker


@end
上面這個是看管人。

memo.h

//


// memo.h


// memodemo


//// created by zhanggui on 15/8/8.


//#import 


@inte***ce


memo : nsobject


-(memo *)initwithname:(nsstring *)name andwithaddress:(nsstring *)address;


-(nsstring *)getname;


-(nsstring *)getaddress;


@end
memo.m

//


// memo.m


// memodemo


//// created by zhanggui on 15/8/8.


//#import "memo.h"


@implementation


memo


-(memo *)initwithname:(nsstring *)name andwithaddress:(nsstring *)address


-(nsstring *)getaddress


-(nsstring *)getname


@end
上面這個是備忘錄。

student.h

//


// student.h


// memodemo


//// created by zhanggui on 15/8/8.


//#import 


@class


memo; @inte***ce


student : nsobject


@property(nonatomic,strong)nsstring *myname;


@property(nonatomic,strong)nsstring *address;


-(memo *)creatememo;


-(void)setmemo:(memo *)memo;


-(void)display;


@end
student.m

//


// student.m


// memodemo


//// created by zhanggui on 15/8/8.


//#import "student.h"


#import "memo.h"


@implementation


student


-(memo *)creatememo 


-(void)setmemo:(memo *)memo


-(void)display


@end
上面這個是student。然後看一下具體的呼叫：

//


// viewcontroller.m


// memodemo


//// created by zhanggui on 15/8/8.


//#import "viewcontroller.h"


#import "memo.h"


#import "caretaker.h"


#import "student.h"


@inte***ce


viewcontroller () @end


@implementation


viewcontroller


- (void)viewdidload 


@end
也就是把zhangsan原來的姓名和位址先儲存到備忘錄中，可是過了一段時間zhangsan不行用自己的新名字和位址了,所有就通過備忘錄來還原自己的姓名和位址。
