CachyKit

Description

Nice threadsafe expirable cache management that can cache any object. Supports fetching from server, single object expire date, UIImageView loading etc.

Installation

Cocoapods

CachyKit is available through CocoaPods. To install it, simply add the following line to your Podfile:

pod 'CachyKit'

then run

$ pod repo update

$ pod install

Features

Usage

import CachyKit

If you want to download and cache a file(JSON, ZIP, UIImage or any type) then simply call with a url

 let cachy = CachyLoader()

 cachy.loadWithURL(URL(string: "http://your_url_here")!) { [weak self] data, _ in
    // Do whatever you need with the data object
 }

You can also cache with URLRequest

let cachy = CachyLoader()

let request = URLRequest(url: URL(string: "http://your_url_here")!)
cachy.loadWithURLRequest(request) { [weak self] data, _ in
    // Do whatever you need with the data object
 }

if you want set expiry date for each object

let cachy = CachyLoader()

//(optional) if isRefresh = true it will forcefully refresh data from remote server
//(optional) you can set **expirationDate** according to your need

cachy.loadWithURL(URL(string: "http://your_url_here")!,isRefresh = false,expirationDate = ExpiryDate.everyDay.expiryDate()) { [weak self] data, _ in
     // Do whatever you need with the data object
  }

Clear all cache

CachyLoaderManager.shared.clear()

CachyLoader has also UIImageView extension.

//(optional) if isShowLoading is true it will show a loading indicator
imageView.cachyImageLoad("your URL", isShowLoading: true, completionBlock: { _, _ in })

It will download, cache and load UIImage into your UIImageView CachyLoader is also configurable, by calling function CachyLoaderManager.shared.configure()

// All the parametre is optional
// Here if you want set how much much memory/disk should use set memoryCapacity, diskCapacity
// To cache only on memory set isOnlyInMemory which is true by default
// You may set expiry date for all the cache object by setting expiryDate
// Your objects may not be conforming to `NSSecureCoding`, set this variable to `false`

CachyLoaderManager.shared.configure(
     memoryCapacity: 1020,
     maxConcurrentOperationCount: 10,
     timeoutIntervalForRequest: 3,
     expiryDate: ExpiryDate.everyWeek,
     isOnlyInMemory: true,
     isSupportingSecureCodingSaving: false
)

expiryDate parametre takes

.never to never expire the cache object
.everyDay to expire at the end of the day
.everyWeek to expiry after a week
.everyMonth to set the expiry date each month
.seconds to set the expiry after some seconds

Without CachyLoader

To cache using CachyLoader is the easiest way to do, but if you want manage your caching, sycning and threading CachyKit also supports that.

Configuration

Here is how you can setup some configuration options

Cachy.countLimit = 1000 // setup total count of elements saved into the cache

Cachy.totalCostLimit = 1024 * 1024 // setup the cost limit of the cache

Cachy.shared.expiration = .everyDay // setup expiration date of each object in the cache

Cachy.shared.isOnlyInMemory = false // will be cached on Memory only or both

Adding/Fetching objects

If you want to add or fetch an object you just follow these simple steps:

//1. Create a CachyObject
let object = CachyObject(value: "HEllo, Worlds", key: "key")

// A given expiry date will be applied to the item
let object2 = CachyObject(value: "HEllo, Worlds", key: "key",expirationDate: ExpiryDate.everyDay.expiryDate())

//2. Add it to the cache
Cachy.shared.add(object: object)

//3. Fetch an object from the cache
let string: String? = Cachy.shared.get(forKey: "key")
