SAMCache

Simple in memory and on disk cache. It's backed by an NSCache in memory, so it automatically purges itself when memory gets low. Purged memory keys will automatically be loaded from disk the next time the are requested.

Usage

The API is simple.

- (id)objectForKey:(NSString *)key;
- (void)objectForKey:(NSString *)key usingBlock:(void (^)(id <NSCopying> object))block;
- (void)setObject:(id <NSCopying>)object forKey:(NSString *)key;

You can also use subscripts:

SAMCache *cache = [SAMCache sharedCache];
cache[@"answer"] = @42;
NSLog(@"The answer is %@", cache[@"answer"]);

See SAMCache.h for the full list of methods.

Adding to Your Project

Simply add SAMCache.h and SAMCache.m to your project or if you're using CocoaPods, simply add 'SAMCache' to your Podfile.
