UIRefreshControl without UITableViewController

🔄 Using UIRefreshControl without UITableViewController - A Sneaky Trick! 💡📲

So, you love the cool new iOS 6 UIRefreshControl class for implementing pull-to-refresh functionality in your app. But, there's just one problem - you prefer using a UIViewController with a UITableView subview, rather than a UITableViewController subclass. Fear not, my friend, for there is a sneaky way to achieve your desired magic! 😎

The Dilemma: 🤔🚫

The question at hand is whether it's possible to utilize the powerful UIRefreshControl without the need for a UITableViewController subclass. Luckily, the answer is YES. You can definitely leverage UIRefreshControl in your UIViewController with a UITableView subview! 🎉

The Solution: ✔️🤓

To make this happen, you need to follow a few simple steps:

1. Create a Reference to Your UITableView: First, create an outlet for your UITableView in your UIViewController class. You can do this by adding the following code snippet to your UIViewController subclass:

@IBOutlet weak var tableView: UITableView!

1. Instantiate UIRefreshControl: Next, you'll need to instantiate an instance of UIRefreshControl in your UIViewController class. This is done as follows:

let refreshControl = UIRefreshControl()

1. Add UIRefreshControl to UITableView: Now, you'll need to add the UIRefreshControl instance to your UITableView subview. Place the following code snippet inside your viewDidLoad() method:

if #available(iOS 10.0, *) {
    tableView.refreshControl = refreshControl
} else {
    tableView.addSubview(refreshControl)
}

1. Implement Refresh Action: 👆➡️💫 Lastly, implement the action that will be triggered when the user pulls down to refresh. You can add the following code snippet to your UIViewController subclass:

refreshControl.addTarget(self, action: #selector(refresh), for: .valueChanged)

Make sure to also implement the refresh() function anywhere within your UIViewController class. This function will contain the logic to refresh your data and update your table view.

Example: 🌟💻

Here's a quick example to reinforce the steps discussed above:

1. In your UIViewController subclass, add the following code snippet to create an outlet for your UITableView:

@IBOutlet weak var tableView: UITableView!

1. Next, create an instance of UIRefreshControl:

let refreshControl = UIRefreshControl()

1. Add the UIRefreshControl instance to your UITableView subview:

if #available(iOS 10.0, *) {
    tableView.refreshControl = refreshControl
} else {
    tableView.addSubview(refreshControl)
}

1. Implement the refresh() function and the associated action:

@objc private func refresh() {
    // Add your data refreshing and table view updating logic here
}

Conclusion and Call-to-Action: 🏁📣

Congratulations, you've successfully unleashed the power of UIRefreshControl in your UIViewController with a UITableView subview! Now, go ahead and implement this sneaky trick in your app to create a delightful pull-to-refresh experience for your users. Happy refreshing! 😄
