Pull to refresh UITableView without UITableViewController

✨Mastering Pull to Refresh in UITableView without UITableViewController✨

👋 Hey there, tech enthusiasts and iOS developers! Today, we have a mind-blowing topic to tackle: implementing the pull-to-refresh feature in a UITableView without the use of a UITableViewController. 🚀

🤔 The Dilemma

So, you want to create a pull-to-refresh feature in a UITableView that is embedded within a UIViewController. However, 🚫 using a UITableViewController isn't an option for you because you want your UITableView to be a smaller subview within the view controller, with some additional content placed above it. You've come to the right place! We've got your back! 😉

💡 The Solution

Implementing the pull-to-refresh feature in a UITableView within a UIViewController requires a multi-step approach. Fear not! We'll guide you through it, step by step. Let's dive right in, shall we? 🏊‍♂️

1. Add UIRefreshControl: First, add a UIRefreshControl object as a property of your UIViewController class. This control handles the pull-to-refresh behavior.

private lazy var refreshControl: UIRefreshControl = {
    let control = UIRefreshControl()
    control.addTarget(self, action: #selector(refreshData(_:)), for: .valueChanged)
    control.tintColor = .gray // Customize the loading indicator color if you wish
    return control
}()

1. Configure UITableView: Make sure your UITableView is properly configured to work with the pull-to-refresh control. You'll need to add the refreshControl to your table view and specify the target-action method.

override func viewDidLoad() {
    super.viewDidLoad()
    tableView.addSubview(refreshControl)
    // Additional setup code...
}

1. Handle Refresh Action: Implement the method specified in the target-action setup from step 2. Here, you can perform any necessary data fetching or update operations.

@objc private func refreshData(_ sender: UIRefreshControl) {
    // Perform data fetching or update operations here...
    DispatchQueue.main.asyncAfter(deadline: .now() + 2.0) {
        sender.endRefreshing()
    }
}
