Introduction
Welcome to the documentation for the PersistentObject framework! This framework is designed to simplify the process of working with persistent data objects in iOS applications. With PersistentObject, you can easily manage the storage and retrieval of data objects, making it easier to implement features such as data persistence, caching, and data synchronization.
Installation
To start using PersistentObject in your project, you can install it using CocoaPods. Simply add the following line to your Podfile:
pod 'PersistentObject'
Quick Start Guide
If you are new to PersistentObject, this quick start guide will help you get started with the basic setup and usage. Follow these steps:
Step 1: Import the framework
In your project file, ensure that you import the PersistentObject framework:
import PersistentObject
Step 2: Create your data object
Create a Swift class that represents your data object. For example, let’s say we want to create a “Person” object with properties such as name and age:
class Person: PersistentObject {
var name: String
var age: Int
init(name: String, age: Int) {
self.name = name
self.age = age
}
}
Step 3: Save and retrieve data
Now, you can easily save and retrieve instances of your data object using the save()
and retrieve()
methods provided by PersistentObject:
let person = Person(name: "John", age: 30)
person.save()
let retrievedPerson = Person.retrieve() // Retrieves the previously saved person
Advanced Usage
Once you’ve familiarized yourself with the basics, you can explore the advanced features and capabilities of PersistentObject. Here are some areas to explore:
Custom Storage Directory
By default, PersistentObject saves data to the user’s document directory. However, you can specify a custom storage directory by setting the storageDirectoryURL
property of your PersistentObject subclass. This allows you to control where the data is stored.
Data Synchronization
PersistentObject provides mechanisms to synchronize your data with a remote server or other data sources. You can override the upload()
and download()
methods to implement your own synchronization logic.
Caching
PersistentObject includes built-in caching functionality. By default, objects are retrieved from cache if available, and only loaded from disk if necessary. You can customize the caching behavior by implementing the shouldLoadFromDisk()
and shouldSaveToDisk()
methods.
