Introduction
Welcome to the WHC Model documentation! Here, you will find comprehensive information about the WHC Model, its features, and how to use it in your projects. WHC Model is a powerful framework designed to simplify data modeling and storage in iOS applications. Whether you are a beginner or an experienced developer, this documentation will guide you through the setup process and provide examples for a better understanding of the framework’s capabilities.
Installation
Before you start using the WHC Model framework, you need to install it in your project. Here’s how you can do that:
- Open Terminal and navigate to your project’s folder.
- Run the following command to install WHC Model using CocoaPods:
“`bash
pod ‘WHC_Model’
“`
Make sure to import the WHCModel header file in your project’s files where you want to use it.
Getting Started
Once you have installed the WHC Model framework, you’re ready to get started. This section will provide you with the necessary steps to begin using the framework effectively.
1. Creating a Model Class
The foundation of the WHC Model framework is based on creating model classes for data entities. A model class represents a specific entity or object in your application. Here’s how you can create a model class:
– Open Xcode and create a new Swift/Objective-C file.
– Name the file based on your entity (e.g., “UserModel.swift”).
– Inherit from the WHC_BaseModel class and define properties for your model.
“`swift
import WHC_Model
class UserModel: WHC_BaseModel {
var id: String?
var name: String?
var email: String?
// Additional properties and methods
}
“`
Remember to replace “UserModel” with the appropriate name for your entity. You can add more properties and methods as per your requirements.
2. Mapping Properties
Mapping properties allows you to define the relationship between your model class properties and the corresponding data fields in your database or API response. To map properties, you need to implement the WHC_Mapper protocol in your model class. Here’s an example of property mapping:
“`swift
import WHC_Model
class UserModel: WHC_BaseModel, WHC_Mapper {
var id: String?
var name: String?
var email: String?
required init() {
super.init()
// Set mapping for each property
id ??= “userId”
name ??= “userName”
email ??= “userEmail”
}
}
“`
In the above example, the properties “id,” “name,” and “email” are mapped to the respective fields in the database or API response. By using this mapping, WHC Model automatically populates these properties when mapping data.
3. Saving and Retrieving Data
With your model class ready, you can now save and retrieve data using the WHC Model framework. Here’s an example of saving data:
“`swift
let user = UserModel()
user.id = “123”
user.name = “John Doe”
user.email = “john.doe@example.com”
do {
try user.save() // Save the user model
} catch let error {
print(“Error: \(error.localizedDescription)”)
}
“`
In the above example, a new user model instance is created, and properties are assigned values. The save() method persists the data in the underlying data store. If any error occurs during the save process, an error message will be printed.
To retrieve data, you can use the following code snippet:
“`swift
do {
let users: [UserModel] = try UserModel.all() // Retrieve all user models
for user in users {
print(“User: \(user.name ?? “”) – Email: \(user.email ?? “”)”)
}
} catch let error {
print(“Error: \(error.localizedDescription)”)
}
“`
In this example, the all() method retrieves all user models that have been previously saved. The retrieved data is stored in an array of UserModel objects, which can be used as desired.
Conclusion
Congratulations! You’ve successfully learned the basics of using the WHC Model framework in your iOS projects. This documentation covered important steps, including installation, creating model classes, mapping properties, and saving/retrieving data. You are now equipped with the necessary knowledge to build robust data models and manage data efficiently in your applications using WHC Model.
