When developing iOS applications, ensuring a smooth user experience is crucial. One common issue developers encounter is how to dismiss the keyboard when the user taps outside of a text field. This guide will walk you through how to implement this functionality using Swift, making your app more user-friendly and intuitive.
Step-by-Step Solution
Below is a simple and effective method to dismiss the keyboard by tapping anywhere on the screen. This approach uses a gesture recognizer to detect taps and then resigns the first responder status of the view, which effectively hides the keyboard.
Implementing the Gesture Recognizer
First, you need to add a tap gesture recognizer to your view. This can be done in the viewDidLoad method of your view controller:
override func viewDidLoad() {
super.viewDidLoad()
// Looks for single or multiple taps.
let tap = UITapGestureRecognizer(target: self, action: #selector(UIInputViewController.dismissKeyboard))
// Uncomment the line below if you want the tap not to interfere and cancel other interactions.
// tap.cancelsTouchesInView = false
view.addGestureRecognizer(tap)
}
// Calls this function when the tap is recognized.
@objc func dismissKeyboard() {
// Causes the view (or one of its embedded text fields) to resign the first responder status.
view.endEditing(true)
}
Using an Extension for Reusability
If you need this functionality across multiple view controllers, you can create an extension for UIViewController:
extension UIViewController {
func hideKeyboardWhenTappedAround() {
let tap = UITapGestureRecognizer(target: self, action: #selector(UIViewController.dismissKeyboard))
tap.cancelsTouchesInView = false
view.addGestureRecognizer(tap)
}
@objc func dismissKeyboard() {
view.endEditing(true)
}
}
Then, in each view controller where you want this behavior, simply call the hideKeyboardWhenTappedAround method in viewDidLoad:
override func viewDidLoad() {
super.viewDidLoad()
self.hideKeyboardWhenTappedAround()
}
