tiny object cache for iOS

cacheableobject

1. setup:

   #import "CacheableObject.h"
   
   /* In your ApplicationDelegate: */
   \- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
     // ...
     [ObjectCache cacheWithStoreType:ObjectCacheStoreTypeMemory];
     //...
   }

2. usage:

   @interface Fruit : NSObject
   
   @end
   
   @implementation Fruit
   
   -(NSString *)id {
     /* This is the 200th apple, but obviously this is intended to be dynamic */
     return @"apple-200"; 
   }
   
   @end
   
   
   [myObject cache];
   [ObjectCache cachedObjectWithID:@"apple-200"];

Yay!

You can also cache objects until a certain time:

[myObject cacheUntil:(NSDate*)theCowsComeHome];

or for a certain number of seconds:

[myObject cacheUntil:3600];

don't forget to clean up when your users say bye-bye.

/* In your ApplicationDelegate: */
- (void)applicationDidEnterBackground:(UIApplication *)application {
  int count = [ObjectCache removeExpired];
  NSLog(@"Purged %d naughty, expired objects.", count);
}

backing stores

• memory
• disk
• sqlite3 (coming later)
