How to Hide Keyboard in Swift on Pressing Return Key?

Are you struggling with hiding the keyboard on pressing the return key in your Swift app? Don't worry, you're not alone! Many developers face this common issue while using UITextField. But fear not, we've got you covered with some easy solutions. Let's dive in!

The Problem

So, you've implemented the textFieldShouldReturn method in your code, expecting the keyboard to disappear when the user presses the return key. However, the resignFirstResponder method is not being called, and the keyboard stubbornly stays on the screen. Frustrating, right?

The Solution

Fear not, my friend! We have a couple of solutions to tackle this problem. Let's discuss them one by one.

Solution 1: Implement UITextFieldDelegate

First things first, ensure that your class adopts the UITextFieldDelegate. Without this, the textFieldShouldReturn method won't be triggered. Here's how you should do it:

class YourViewController: UIViewController, UITextFieldDelegate {
    // Your code here
}

By adopting the UITextFieldDelegate, you'll now be able to override the necessary methods.

Solution 2: Set the Delegate

Make sure to set the delegate of your UITextField to the current class (most likely, your view controller). This connection is essential for the delegate methods to be called. Here's an example:

yourTextField.delegate = self

Solution 3: Resign First Responder

To hide the keyboard when the return key is pressed, you need to call the resignFirstResponder method on the active text field. Add the following code inside your textFieldShouldReturn method:

func textFieldShouldReturn(_ textField: UITextField) -> Bool {
    textField.resignFirstResponder()
    return true
}

By resigning the first responder, you're telling the text field to let go of its focus and pass it on to something else, thus hiding the keyboard.

The Full Code

Here's what your code should look like once you've implemented the above solutions:

class YourViewController: UIViewController, UITextFieldDelegate {
    @IBOutlet weak var yourTextField: UITextField!

    override func viewDidLoad() {
        super.viewDidLoad()
        yourTextField.delegate = self
    }

    func textFieldShouldReturn(_ textField: UITextField) -> Bool {
        textField.resignFirstResponder()
        return true
    }
}

Now, when the user presses the return key, the keyboard will disappear and your UI will be much cleaner.

Conclusion

Congratulations! You've learned how to hide the keyboard in Swift on pressing the return key. By implementing the UITextFieldDelegate and setting the delegate for your text field, you're now able to call the resignFirstResponder method and achieve the desired functionality.
