📝 Blog Post: Easy Way to Dismiss Keyboard: Say Goodbye to Looping Through Controls! 🖐️

Are you tired of spending endless hours looping through controls just to dismiss the keyboard in your app? 😩 We feel you! 😓

In this blog post, we're going to reveal a super easy solution to your problem, saving you time and hassle. 💪✨ Say goodbye to the tedious process of resigning all your controls as the first responder. 👋

The Problem: Getting the Current First Responder

So, you have a bunch of controls scattered throughout your table cells, and you're wondering if there's a simpler way to dismiss the keyboard in your app. 🤔 Specifically, you're curious about how to get the current first responder to the keyboard. Let's dive into it!

func getCurrentFirstResponder() -> UIResponder? {
    var responder: UIResponder? = nil
    
    // Loop through the windows
    for window in UIApplication.shared.windows {
        responder = window.perform(#selector(findFirstResponder))
        if responder != nil {
            break
        }
    }
    
    return responder
}

As you can see, the above code snippet allows you to retrieve the current first responder in your app by looping through the windows. 🌐✨ But fear not, we have a simpler solution for you!

The Easy Solution: UIResponder Extension 🎉

Instead of writing complex code and looping through all the controls, we can simplify the process by extending UIResponder. 🙌

extension UIResponder {
    static var currentFirstResponder: UIResponder? {
        _currentFirstResponder = nil
        UIApplication.shared.sendAction(#selector(findFirstResponder), to: nil, from: nil, for: nil)
        return _currentFirstResponder
    }
    
    private static weak var _currentFirstResponder: UIResponder?
    
    @objc private func findFirstResponder() {
        UIResponder._currentFirstResponder = self
    }
}

Now, you can easily dismiss the keyboard without going through all the hustle and bustle. 😌 Simply call UIResponder.currentFirstResponder?.resignFirstResponder() and voilà! Your keyboard is gone! 💨
