Welcome to the documentation for the RedownloadTasksQueue library! This library provides a queue-based solution for managing tasks related to redownloading content in iOS apps. This documentation will guide you through the usage and integration of the RedownloadTasksQueue library into your projects.
Installation
To integrate the RedownloadTasksQueue library into your project, follow the steps below:
- Open your Xcode project.
- Go to “File” > “Swift Packages” > “Add Package Dependency”.
- Enter the URL of the RedownloadTasksQueue repository: https://github.com/YOUR_USERNAME/RedownloadTasksQueue.git
- Choose the version or branch you want to use.
- Click “Next” and wait for Xcode to resolve the package.
- Finally, click “Finish” to complete the integration.
Usage
The RedownloadTasksQueue library provides a simple API for managing a queue of redownload tasks. To start using the library, follow the steps below:
Creating a Queue
To create a new queue, use the following code:
let queue = RedownloadTasksQueue()
Adding Tasks
To add a new task to the queue, use the addTask(_ task: RedownloadTask)
method. Here’s an example:
let task = RedownloadTask(url: imageURL, filename: "image.png")
queue.addTask(task)
Starting the Queue
To start processing the tasks in the queue, use the start()
method:
queue.start()
Monitoring Task Progress
The RedownloadTasksQueue library provides a delegate protocol, RedownloadTasksQueueDelegate
, for monitoring the progress of tasks. Implement the delegate methods to receive updates on task progress. Here’s an example implementation:
class MyViewController: UIViewController, RedownloadTasksQueueDelegate {
// ...
func redownloadTasksQueue(_ queue: RedownloadTasksQueue, taskDidComplete task: RedownloadTask) {
// Task completed successfully
// Update UI or perform further actions
}
func redownloadTasksQueue(_ queue: RedownloadTasksQueue, taskDidFail task: RedownloadTask, error: Error) {
// Task failed with error
// Handle the error or retry the task
}
// ...
}
Canceling Tasks
To cancel a specific task, use the cancelTask(_ task: RedownloadTask)
method. Here’s an example:
queue.cancelTask(task)
To cancel all tasks in the queue, use the cancelAllTasks()
method:
queue.cancelAllTasks()
Canceled tasks won’t be processed further and their delegate methods won’t be called.
Handling Errors
If an error occurs during the redownload process, the delegate method redownloadTasksQueue(_:taskDidFail:error:)
will be called. This method provides the specific task that failed and the associated error. Handle the error accordingly, for example, by displaying an error message to the user or retrying the task.
Conclusion
The RedownloadTasksQueue library simplifies the management of redownload tasks in iOS apps. By following this documentation, you should now have a good understanding of how to integrate and use the library in your projects. If you have any further questions or issues, feel free to consult the project’s GitHub repository or reach out to the library’s author.
