The UISearchBar is a powerful tool for search functionality in iOS apps. However, one common issue that many developers face is how to dismiss the keyboard when the search is complete or when the user wants to cancel the search. In this article, we will explore how to dismiss the keyboard from UISearchBar with the X button tap.
First, let's take a look at the default behavior of the UISearchBar when the user taps on the search bar. The keyboard automatically appears, allowing the user to start typing their search query. However, when the user taps on the search button, the keyboard does not automatically dismiss. This can be frustrating for users who want to quickly cancel their search and return to the previous screen.
To solve this issue, we need to implement the delegate method for UISearchBarDelegate. This method is called when the user taps on the search button or the cancel button. We will use this method to dismiss the keyboard when the user taps on the cancel button.
func searchBarSearchButtonClicked(_ searchBar: UISearchBar) {
searchBar.resignFirstResponder()
}
By calling the resignFirstResponder() method, we are essentially telling the search bar to give up its first responder status, which in turn dismisses the keyboard.
Next, we need to handle the tap event on the cancel button. By default, the cancel button does not have any functionality attached to it. We will add a target to the cancel button and call the same method we used for the search button.
searchBar.showsCancelButton = true
searchBar.cancelButton.addTarget(self, action: #selector(dismissKeyboard), for: .touchUpInside)
@objc func dismissKeyboard() {
searchBar.resignFirstResponder()
}
Now, when the user taps on the cancel button, the keyboard will be dismissed. However, there is one more step we need to take to fully dismiss the keyboard. The UISearchBar has a built-in X button on the right side, which is used to clear the search text. When the user taps on this button, the keyboard should also be dismissed.
To handle this scenario, we will use a delegate method called searchBarCancelButtonClicked. This method is called when the user taps on the X button.
func searchBarCancelButtonClicked(_ searchBar: UISearchBar) {
searchBar.resignFirstResponder()
}
With these three steps, we have successfully implemented the functionality to dismiss the keyboard from UISearchBar with the X button tap. Now, when the user taps on the search button, the cancel button, or the X button, the keyboard will be dismissed, providing a better user experience.
In conclusion, the UISearchBar is a powerful tool for search functionality in iOS apps, and with a few simple steps, we can easily handle the dismissal of the keyboard when the search is complete or when the user wants to cancel the search. By implementing the delegate methods for UISearchBarDelegate and handling the tap events on the cancel button and the X button, we can provide a seamless and intuitive user experience. I hope this article has been helpful in solving the issue of dismissing the keyboard from UISearchBar. Happy coding!
