Edited for Swift 4 Edit: Added @objc. While this isn’t the best option for performance, one instance of it here shouldn’t cause too many problems until there is a better solution. Edited to fix when needing to interact with items behind GestureRecognizer. Edit: Thanks @Rao for pointing this out. Added tap.cancelsTouchesInView = false. This should … Read more
This works for me: import UIKit class ViewController: UIViewController, UITextViewDelegate { @IBOutlet weak var textView: UITextView! override func viewDidLoad() { super.viewDidLoad() textView.delegate = self } /* Updated for Swift 4 */ func textView(_ textView: UITextView, shouldChangeTextIn range: NSRange, replacementText text: String) -> Bool { if(text == “\n”) { textView.resignFirstResponder() return false } return true } … Read more
I’ve just encountered this exception running a Xamarin app on the simulator. It started occurring after I toggled the software keyboard off while debugging the app. Given the exception mentioning the keyboard I think that’s what caused it. Uninstalling the app from the emulator, cleaning and rebuilding fixed the issue for me. Unsure if this … 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
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
I wrote an extension method to do this for me and it’s pretty fast: extension XCUIElement { /** Removes any current text in the field before typing in the new value – Parameter text: the text to enter into the field */ func clearAndEnterText(text: String) { guard let stringValue = self.value as? String else { … 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
First you need to conform to the UITextFieldDelegate Protocol in your View/ViewController’s header file like this: @interface YourViewController : UIViewController <UITextFieldDelegate> Then in your .m file you need to implement the following UITextFieldDelegate protocol method: – (BOOL)textFieldShouldReturn:(UITextField *)textField { [textField resignFirstResponder]; return YES; } [textField resignFirstResponder]; makes sure the keyboard is dismissed. Make sure you’re … 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
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
