pod 'ObjectMapperCacheManager'

Usage

When store something to a device, "key" is the only identifier, just like UserDefaults in Foundation.

UserDefaults.standard.setValue(["name": "James", "age": 16], forKey: "User")

But, the difference between UserDefaults and CacheManager is the directory in sandbox:

UserDefaults: Home/Library/Preference/
CacheManager: Home/Library/Caches

1. Store key-value data

The data could be a dict or an array

let dict: [String: Any] = ["name": "James", "age": 16]
CacheManager.setCache(json: dict, for: "Json")

let dictArray = [[String: Any]] = [dict]
CacheManager.setCache(json: dictArray, for: "JsonArray")

2. Get cached key-value data

// must declare the type
if let dict: [String: Any] = CacheManager.cacheJson(for: "Json") as? [String: Any]{  
  print(dict)
}

if let array: [[String: Any]] = CacheManager.cacheJson(for: "JsonArray") as? [String: Any]{  
  print(array)
}

3. Store an object or an array of ObjectMapper

The only requirement is that the object must conform to ObjectMapper's Mappable protocol.

let user: User = User()
CacheManager.setCache(object: user, for: "Object")

let userList = [user]
CacheManager.setCache(array: userList, for: "ObjectArray")

4. Get cached object of array

if let user: User = CacheManager.cache(for: "Object") {
}

if let array: [User] = CacheManager.cacheArray(for: "ObjectArray") {
}
