Introduction
Welcome to the complete documentation for the GenericDataSources framework. This framework provides a set of powerful data source classes that can be used in various iOS projects to greatly simplify data loading and management. Whether you are working with local data, remote APIs, or databases, GenericDataSources has got you covered.
Installation
To install the GenericDataSources framework into your project, follow these steps:
- Open your project in Xcode.
- Go to the “File” menu and select “Swift Packages” and then “Add Package Dependency”.
- In the search field, enter “GenericDataSources”.
- Select the most recent version of the framework and click “Next”.
- Choose the target where you want to add the framework and click “Finish”.
Usage
The GenericDataSources framework provides various data source classes that can be used in conjunction with UITableView, UICollectionView, or any other custom view that requires dynamic data.
LocalDataSources
The LocalDataSources module provides classes for handling local data, such as arrays or dictionaries.
DataSourceArray
The DataSourceArray class allows you to load an array of data into a table or collection view. It automatically takes care of data restructuring and pagination.
// Example usage
let dataSource = DataSourceArray<String>()
dataSource.data = ["Item 1", "Item 2", "Item 3"]
dataSource.configureCell = { (item, cell) in
// Configure your cell with the item data
}
tableView.dataSource = dataSource
DataSourceDictionary
The DataSourceDictionary class allows you to load a dictionary of data into a table or collection view. It handles key-value pairs and automatically manages data restructuring and pagination.
// Example usage
let dataSource = DataSourceDictionary<String, String>()
dataSource.data = ["Item 1": "Value 1", "Item 2": "Value 2", "Item 3": "Value 3"]
dataSource.configureCell = { (item, cell) in
// Configure your cell with the item data
}
tableView.dataSource = dataSource
RemoteDataSources
The RemoteDataSources module provides classes for handling remote data sources, such as APIs or web services. It allows you to fetch and parse data from various endpoints.
URLDataSource
The URLDataSource class allows you to load data from a remote API or web service. It handles network requests, JSON parsing, and pagination, providing an easy way to fetch and display data in your views.
// Example usage
let dataSource = URLDataSource<MyModel>()
dataSource.url = URL(string: "https://api.example.com/endpoint")
dataSource.configureCell = { (item, cell) in
// Configure your cell with the item data
}
tableView.dataSource = dataSource
Advanced Usage
The GenericDataSources framework provides powerful customization options to handle various scenarios. Here are some advanced usage examples:
Custom Cell Configuration
You can define your own closure to configure cells in the data source. This allows you to customize the appearance and behavior of each cell based on the data it represents.
// Example usage
dataSource.configureCell = { (item, cell) in
// Configure your custom cell with the item data
if let customCell = cell as? MyCustomCell {
customCell.titleLabel.text = item.title
customCell.descriptionLabel.text = item.description
}
}
Data Manipulation
The GenericDataSources framework provides methods to manipulate data within the data source. This includes filtering, sorting, and adding or removing items from the data array.
// Example usage
dataSource.filter = { (item) in
// Return true to include the item in the data source, false otherwise
return item.category == selectedCategory
}
dataSource.sort = { (item1, item2) in
// Specify your custom sorting logic
return item1.timestamp < item2.timestamp
}
dataSource.add(items: [newItem1, newItem2])
dataSource.remove(item: removedItem)
Pagination
If your data source supports pagination, you can enable it and specify the pagination parameters. This allows you to load data in chunks and efficiently handle large datasets.
// Example usage
dataSource.paginationEnabled = true
dataSource.pageSize = 20
dataSource.fetchNextPage = { (page) in
// Fetch the next page of data using the provided page number
}
Conclusion
The GenericDataSources framework is a powerful tool for managing and loading dynamic data in your iOS projects. Whether you are working with local data or remote APIs, this framework provides a streamlined approach to handle data sources, allowing you to focus on building great user experiences.
