当C++遇到IOS应用开发---LRUCache缓存(6)

        HashKey hash_key; 
        hash_key.key = key; 
        clu_cache->set(hash_key, value); 
        rwlock_wunlock(lock); 
    } 
    
    id get(NSString* key){ 
        HashKey hash_key; 
        hash_key.key = key; 
        HashValue* value = clu_cache->get(hash_key); 
        if(value == NULL){ 
            return nil; 
        } 
        else{ 
            return value->value_; 
        } 
    } 
}; 
 
#endif 

 

    最后看一下如何使用：
[cpp]
void testLRUCache(){ 
    //指针方式 
    DZCache::instance()->set(@"name", @"daizhj");//设置 
    NSString* name = (NSString*)DZCache::instance()->get(@"name");//获取 
    std::cout<<[name UTF8String]<<endl; 
    
    NSNumber * age=[NSNumber numberWithInt:123123]; 
    DZCache::instance()->set(@"age", age); 
    age = (NSNumber*)DZCache::instance()->get(@"age"); 
 
    //对象方式 
    DZCache::getInstance().set(@"name", @"daizhenjun"); 
    name = (NSString*)DZCache::getInstance().get(@"name"); 
    std::cout<<[name UTF8String]<<endl; 
    
    age = [NSNumber numberWithInt:123456]; 
    DZCache::getInstance().set(@"age", age); 
    age = (NSNumber*)DZCache::getInstance().get(@"age"); 
}
