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

/**

*
* @return 返回复制的对象
*/
- (id)copyObject;
@end//

@implementation NSObject (ObjectCopy)
- (id)copyObject {
id object = nil;
NSData *data = nil;
if ((data = [FastCoder dataWithRootObject:self])) {
object = [FastCoder objectWithData:data];
}
return object;
}

@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//

#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：

#import "NSObject+ObjectCopy.h"
#import "Model.h"
@interface ViewController ()
@end
@implementation ViewController
- (void)viewDidLoad {
[super viewDidLoad];
// ModelOne
Model *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];
// ModelTwo
Model *model_two = [model_one copyObject];
model_two.name = @"QiuLiang";
model_two.age = @(28);
[model_two info];
}
