Sure, here are the steps on how to detect keyboard show suggestion tapped in Swift code:
Import the UITextField and NSNotificationCenter frameworks.
Create a UITextField object and set its delegate property to an object that implements the UITextFieldDelegate protocol.
In the UITextFieldDelegate protocol, implement the textFieldDidChange: method.
In the textFieldDidChange: method, add an observer for the UIKeyboardWillShowNotification notification.
In the UIKeyboardWillShowNotification notification handler, check if the keyboard is showing a suggestion bar.
If the keyboard is showing a suggestion bar, check if the user tapped on a suggestion.
If the user tapped on a suggestion, do something.
Remove the observer for the UIKeyboardWillShowNotification notification.
Here is an example of how to implement this in Swift:
Swift
import UIKit
import NSNotificationCenter
class ViewController: UIViewController, UITextFieldDelegate {
@IBOutlet weak var otpTextField: UITextField!
override func viewDidLoad() {
super.viewDidLoad()
// Set the delegate property to an object that implements the UITextFieldDelegate protocol.
otpTextField.delegate = self
}
func textFieldDidChange(_ textField: UITextField) {
// Add an observer for the UIKeyboardWillShowNotification notification.
NotificationCenter.default.addObserver(self, selector: #selector(keyboardWillShow(_:)), name: UIKeyboardWillShowNotification, object: nil)
}
@objc func keyboardWillShow(_ notification: NSNotification) {
// Check if the keyboard is showing a suggestion bar.
let keyboardFrame = notification.userInfo?[UIKeyboardFrameEndUserInfoKey] as? CGRect
let suggestionBarFrame = notification.userInfo?[UIKeyboardSuggestionBarFrameEndUserInfoKey] as? CGRect
if keyboardFrame != nil && suggestionBarFrame != nil {
// The keyboard is showing a suggestion bar.
// Check if the user tapped on a suggestion.
if let tappedSuggestion = notification.userInfo?[UIKeyboardSuggestionBarSelectedSuggestionUserInfoKey] as? String {
// The user tapped on a suggestion.
// Do something.
}
}
}
func textFieldDidEndEditing(_ textField: UITextField) {
// Remove the observer for the UIKeyboardWillShowNotification notification.
NotificationCenter.default.removeObserver(self, name: UIKeyboardWillShowNotification, object: nil)
}
}
This code will detect if the user tapped on a suggestion in the keyboard suggestion bar and print a message to the console.
