Create a subclass of UITextField like this: class EmojiTextField: UITextField { // required for iOS 13 override var textInputContextIdentifier: String? { “” } // return non-nil to show the Emoji keyboard ¯\_(ツ)_/¯ override var textInputMode: UITextInputMode? { for mode in UITextInputMode.activeInputModes { if mode.primaryLanguage == “emoji” { return mode } } return nil } } … Read more
Unfortunately, you can change “Return” into only one of these predefined labels with the returnKeyType property: Return (default) Go Google Join Next Route Search Send Yahoo Done Emergency Call Continue (as of iOS 9) So maybe you should choose “Next” if a data entry kind of activity is what you’re after. More information here.
There is a keyboardType property for a UITextField: typedef enum { UIKeyboardTypeDefault, // Default type for the current input method. UIKeyboardTypeASCIICapable, // Displays a keyboard which can enter ASCII characters, non-ASCII keyboards remain active UIKeyboardTypeNumbersAndPunctuation, // Numbers and assorted punctuation. UIKeyboardTypeURL, // A type optimized for URL entry (shows . / .com prominently). UIKeyboardTypeNumberPad, // … Read more
There are some problems in your line: var keyboardSize = notification.userInfo(valueForKey(UIKeyboardFrameBeginUserInfoKey)) notification.userInfo returns an optional dictionary [NSObject : AnyObject]?, so it must be unwrapped before accessing its values. The Objective-C NSDictionary is mapped to a Swift native Dictionary, so you must use the dictionary subscript syntax (dict[key]) to access the values. The value must be … Read more
Swift You can get the keyboard height by subscribing to the UIKeyboardWillShowNotification notification. (Assuming you want to know what the height will be before it’s shown). Swift 4 NotificationCenter.default.addObserver( self, selector: #selector(keyboardWillShow), name: UIResponder.keyboardWillShowNotification, object: nil ) @objc func keyboardWillShow(_ notification: Notification) { if let keyboardFrame: NSValue = notification.userInfo?[UIResponder.keyboardFrameEndUserInfoKey] as? NSValue { let keyboardRectangle = … Read more
I set the delegate of the UITextField to my ViewController class. In that class I implemented this method as following: – (BOOL)textFieldShouldReturn:(UITextField *)textField { [textField resignFirstResponder]; return NO; }
This is how you might handle the problem on a SSN verification field, you can modify the max length and remove the if statement checking for keyboard type if you need to. There is also logic to suppress the max length alerts when the user is typing as opposed to pasting data. Within the context … Read more
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 not 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 … Read more
This is easily done by creating a UITapGestureRecognizer object (by default this will detect a “gesture” on a single tap so no further customization is required), specifying a target/action for when the gesture is fired, and then attaching the gesture recognizer object to your table view. E.g. Perhaps in your viewDidLoad method: UITapGestureRecognizer *gestureRecognizer = … Read more
Here is a solution, without handling the switch from one textField to another: override func viewDidLoad() { super.viewDidLoad() NSNotificationCenter.defaultCenter().addObserver(self, selector: Selector(“keyboardWillShow:”), name: UIKeyboardWillShowNotification, object: nil) NSNotificationCenter.defaultCenter().addObserver(self, selector: Selector(“keyboardWillHide:”), name: UIKeyboardWillHideNotification, object: nil) } func keyboardWillShow(notification: NSNotification) { if let keyboardSize = (notification.userInfo?[UIKeyboardFrameEndUserInfoKey] as? NSValue)?.CGRectValue() { self.view.frame.origin.y -= keyboardSize.height } } func keyboardWillHide(notification: NSNotification) { self.view.frame.origin.y … Read more
