缓存结构对象 [英] Caching the struct Object

问题描述

如何在Objective-C中为结构指针对象创建缓存？是否有任何第三方组件可以像Java和.NET一样缓存对象？

How do I create a cache for a struct pointer object in Objective-C? Is there any third party component for caching objects as Java and .NET have?

我具有以下结构：

typedef struct _news {
  references
  char *headline;
  char *story_url;
} news;

在接口类中，我有一个以上结构的双指针。我想使用Objective-C将其缓存一段时间。

I have a double pointer for the above struct in an interface class. I would like to cache it for some time using Objective-C.

// save
NSMutableData *data = [[NSMutableData alloc] init];
[data appendBytes:&p length:sizeof(news)];

// read
struct news *begin = (struct news *)[data bytes];
