SwiftlyCache

Swiftlycache is a thread safe IOS general cache library written with swift 5.

Features

• Support all data types complying with the codable protocol
• Objects can be evicted with least-recently-used algorithm
• It can be configured to automatically recycle objects or manually recycle objects when receiving memory warnings or when the application enters the background
• Using subscript can make reading and writing data more convenient
• Support reading data using sequence generator

Installation

CocoaPods

1.Add pod 'SwiftlyCache' to your Podfile
2.Run pod install or pod update
3.import SwiftlyCache

Manually

1.Download all the files in the SwiftlyCache subdirectory
2.Add the source files to your Xcode project

Example:

Cache a struct complying with the codable protocol

struct Student:Codable {
     var name:String
     var age:Int
     
     init(name:String,age:Int) {
         self.name = name
         self.age = age
     }
 }

let cache = MultiCache<Student>()

let shirley = Student(name: "shirley", age: 30)

Set key and value to be cached

cache.set(forKey: "shirley10", value: shirley)

Query the corresponding value according to the given key

if let object = cache.object(forKey: "shirley1"){
    print("当前Student是:\(object)")
}

Query whether the corresponding value exists in the cache according to key

let isExists = cache.isExistsObjectForKey(forKey: "shirley20")

中文介绍

SwiftlyCache是用 Swift 5编写的一个线程安全的iOS通用缓存库。

特性:

• 支持所有遵守 Codable协议的数据类型
• 支持LRU淘汰算法
• 当收到内存警告或者App进入后台时,内存缓存可以配置为自动清空或者手动清空
• 支持使用 Subscript，使读写数据更加方便
• 提供了 MultiCacheGennerator、 MemoryCacheGenerator、 DiskCacheGenerator用于支持 for..in、 compactMap、 map、 filter等方法

使用方法:

CocoaPods:

1.在Podfile中添加 pod 'SwiftlyCache'
2.执行 pod install或者 pod update
3.导入 SwiftlyCache

手动导入:

1.下载 SwiftlyCache文件夹内所有内容
2.将 SwiftlyCache内的源文件添加到你的工程

示例:

将一个遵守Codable协议的struct进行缓存

struct Student:Codable {
     var name:String
     var age:Int
     
     init(name:String,age:Int) {
         self.name = name
         self.age = age
     }
 }

let cache = MultiCache<Student>()

let shirley = Student(name: "shirley", age: 30)

设置需要缓存的Key和Value

cache.set(forKey: "shirley10", value: shirley)

根据给定的Key查询对应的Value

if let object = cache.object(forKey: "shirley1"){
    print("当前Student是:\(object)")
}

根据Key查询缓存中是否存在对应的Value

let isExists = cache.isExistsObjectForKey(forKey: "shirley20")
