超简易复制Model对象（为后续备忘录设计模式博文做铺垫）

复制整个Model需要实现NSCopy协议，可以想象是非常麻烦的一件事情，今天我跟大家分享一个不需要你做任何操作的复制Model对象的方法，不过，首先你得先去下载开源代码FastCoder辅助才行。

源码如下：

NSObject+ObjectCopy.h 与 NSObject+ObjectCopy.m

// // NSObject+ObjectCopy.h // FastCoder // // Created by YouXianMing on 15/1/3. // Copyright (c) 2015年 YouXianMing. All rights reserved. // #import <Foundation/Foundation.h>@interface NSObject (ObjectCopy)/*** 复制对象** @return 返回复制的对象*/ - (id)copyObject;@end // // NSObject+ObjectCopy.m // FastCoder // // Created by YouXianMing on 15/1/3. // Copyright (c) 2015年 YouXianMing. All rights reserved. // #import "NSObject+ObjectCopy.h" #import "FastCoder.h"@implementation NSObject (ObjectCopy)- (id)copyObject {id object = nil;NSData *data = nil;if ((data = [FastCoder dataWithRootObject:self])) {object = [FastCoder objectWithData:data];}return object; }@end

Model.h 与 Model.m

// // Model.h // FastCoder // // Created by YouXianMing on 15/1/3. // Copyright (c) 2015年 YouXianMing. All rights reserved. // #import <Foundation/Foundation.h>@interface Model : NSObject@property (nonatomic, strong) NSString *name; // 姓名 @property (nonatomic, strong) NSNumber *age; // 年龄 @property (nonatomic, strong) NSDate *birthDate; // 出身日期 @property (nonatomic, strong) NSArray *subInfo; // 子信息 @property (nonatomic, strong) NSDictionary *address; // 地址- (void)info;@end // // Model.m // FastCoder // // Created by YouXianMing on 15/1/3. // Copyright (c) 2015年 YouXianMing. All rights reserved. // #import "Model.h"@implementation Model- (void)info {NSLog(@"[%@]", self);NSLog(@"name %@", self.name);NSLog(@"age %@", self.age);NSLog(@"birthDate %@", self.birthDate);NSLog(@"subInfo %@", self.subInfo);NSLog(@"address %@", self.address);NSLog(@""); }@end

控制器源码：

// // ViewController.m // http://home.cnblogs.com/u/YouXianMing/ // // Created by YouXianMing on 15/1/3. // Copyright (c) 2015年 YouXianMing. All rights reserved. // #import "ViewController.h" #import "NSObject+ObjectCopy.h" #import "Model.h"@interface ViewController ()@end@implementation ViewController- (void)viewDidLoad {[super viewDidLoad];// ModelOneModel *model_one = [Model new];model_one.name = @"YouXianMing";model_one.age = @(27);model_one.birthDate = [NSDate date];model_one.subInfo = @[@"iOS", @"C++"];model_one.address = @{@"BeiJing": @"TongZhou"};[model_one info];// ModelTwoModel *model_two = [model_one copyObject];model_two.name = @"QiuLiang";model_two.age = @(28);[model_two info]; }@end
