JMCache 0.1

You want to add pod 'JMCache', '~> 0.1' similar to the following to your Podfile:

target 'MyApp' do
  pod 'JMCache', '~> 0.1'
end

Then run a pod install inside your terminal, or from CocoaPods.app.

Alternatively to give it a test run, run the command:

pod try JMCache

JMCache 0.1

JMCache is a key/value store designed for persisting temporary objects fully based on GCD. It is composed of a cache disk and a memory cache (JMCacheMemory).

JMCache is cool because :

it can store object not compliant with NSCoding protocols, you can implement JMcoding protocol or use FastCoding implementation,
you can configure the cache to be "memory then disk", "only memory", "only disk",
you can use a ValueTransformer to increase security of your encoded object, you can zip it, crypt it with your own algorithms.

Cache parameters

Cache path type -> auto path to the save directory

typedef NS_ENUM(NSUInteger, JMCacheType) {
    JMCacheTypePublic,
    JMCacheTypePrivate,
    JMCacheTypeOffline
};

Cache type -> memory, disk

typedef NS_OPTIONS(NSUInteger, JMCacheType) {
    JMCacheTypeInMemory = 1,
    JMCacheTypeOnDisk   = 1 << 1,
    JMCacheTypeInMemoryThenOnDisk   = (JMCacheTypeInMemory | JMCacheTypeOnDisk)
};

ValueTransformer

You can write your own valueTransformer to increase security of your encoded data. For example, see minimalist implemtation of JMCacheReverseDataValueTransformer class.

@property (strong, nonatomic) JMCacheValueTransformer *valueTransformer;
