I need keyboard to be with CapsLock on (please don't answer how to make text in textField uppercased):
You need to specify .autocapitalizationType for your textField in viewDidLoad or somewhere else during setup of the view like so:
override func viewDidLoad() {
super.viewDidLoad()
textField.autocapitalizationType = .allCharacters
}
Now when your textField becomes active, your keyboard will be on caps.
Here are all the possible options for autocapitalizationType.

Hello I am trying to have a number pad appear after a timer is up. Then have my user type numbers on the pad and their input be saved to a variable in my code not a text box. I can't seem to find anything on popping up a number pad without using a text box. Any help is appreciated.
Ok I'm going to give you some code that will greatly help you. You need some sort of UITextView or UITextField to get the system keyboard. So essentially what we will do is have a textField without showing it, and then grab the info off it and store it into the variable.
//Dummy textField instance as a VC property.
let textField = UITextField()
//Add some setup to viewDidLoad
override func viewDidLoad() {
super.viewDidLoad()
textField.delegate = self //Don't forget to make vc conform to UITextFieldDelegateProtocol
textField.keyboardType = .phonePad
//http://stackoverflow.com/a/40640855/5153744 for setting up toolbar
let keyboardToolbar = UIToolbar()
keyboardToolbar.sizeToFit()
let flexBarButton = UIBarButtonItem(barButtonSystemItem: .flexibleSpace, target: nil, action: nil)
let doneBarButton = UIBarButtonItem(barButtonSystemItem: .done, target: self, action: #selector(dismissKeyboard))
keyboardToolbar.items = [flexBarButton, doneBarButton]
textField.inputAccessoryView = keyboardToolbar
//You can't get the textField to become the first responder without adding it as a subview
//But don't worry because its frame is 0 so it won't show.
self.view.addSubview(textField)
}
//When done button is pressed this will get called and initate `textFieldDidEndEditing:`
func dismissKeyboard() {
view.endEditing(true)
}
//This is the whatever function you call when your timer is fired. Important thing is just line of code inside that our dummy code becomes first responder
func timerUp() {
textField.becomeFirstResponder()
}
//This is called when done is pressed and now you can grab value out of the textField and store it in any variable you want.
func textFieldDidEndEditing(_ textField: UITextField) {
textField.resignFirstResponder()
let intValue = Int(textField.text ?? "0") ?? 0
print(intValue)
}
I am using storyboard and this is what I did:
drag-drop a text field
On the storyboard, in the attributes inspector (having selected the text field), under "Drawing", select hidden
make an outlet for the text field in your view controller
make sure your view controller extends the UITextViewDelegate
make your current view controller the delegate
in the required location simply call <textfieldOutlet>.becomeFirstResponder()
Now that this is simply a textfield's data, u can always store the value and use it else where.
How do I create outlets for my keys in a custom keyboard to switch from letters to numbers and symbols? I am trying to create a custom keyboard and I don't know how to create outlets for my keys to switch back and forth from letters to numerals and symbols.
So, I gather from your comment, that this is what you are looking for. The type of keyboard input, is determined by setting the 'keyboardType' property of the keyboard's delegate. If you want to switch and update a view, I think you'll have to dismiss the keyboard and recall it. I find this unsafe, and would highly suggest using a normal keyboard (which has all the characters you need), trusting your user, and sanitizing the input. But the following does work, if you must. In the following, 'txtField' is a UITextField with the UIViewController set as its delegate, the IBAction is wired to a UIButton, and 'isNumbers' is a Bool property of the UIViewController.
#IBAction func switchKeyboards(_ sender: Any) {
if isNumbers {
txtField.keyboardType = UIKeyboardType.alphabet
isNumbers = false
} else {
txtField.keyboardType = UIKeyboardType.numberPad
isNumbers = true
}
txtField.resignFirstResponder()
txtField.becomeFirstResponder()
}
I just made a simple app where you type things in four boxes and can randomly select one. After typing in the boxes I need the keyboard to go away so people can see what the result is, but the on-screen keyboard just stays. Is this something I need to change in the files of the app?
You have to use resignFirstResponder() property of the text field.
If you want to hide the keyboard when a tap occurred outside the text field,
you can use an UITapGestureRecognizer.
override func viewDidLoad() {
super.viewDidLoad()
let tapRecognizer = UITapGestureRecognizer(target: self, action: #selector(backgroundTapped(_:)))
view.addGestureRecognizer(tapRecognizer)
}
func backgroundTapped(sender: UITapGestureRecognizer) {
view.endEditing(true)
}
How to remove focus on NSTextField if I'm not focus in the textField?
I have a NSTextField and I set the Action: Sent On End Editing. After clicking the textField, the FOCUS will always in my NSTextField when I click other places on the view.
Furthermore, I use makeFirstResponder and resignFirstResponder but all in vain. Any idea?
#IBAction func endOfEditing(sender: NSTextField) {
view.window?.makeFirstResponder(nil)
view.window?.resignFirstResponder()
}
For illustration, the FOCUS will always be in textField no matter where I pressed. (Even when I pressed the button)
How can I remove the focus when I click outside the textField?
Just try this: change "view.window?" to "sender"
#IBAction func endOfEditing(sender: NSTextField) {
sender.makeFirstResponder(nil)
sender.resignFirstResponder()
}
Swift 4
For those still troubling with focus and unfocus: I don't know if it was the case back in 2016, but in Swift 4 my NSTextField loses focus except if I click in another "selectable" outlet.
For instance if I click on a NSButton right after NSTextField it won't lost focus. I suspect the NSButton catches the event, preventing the textfield to know it has to unfocus.
Here is a much radical solution which will definitely defocus an NSTextField
#IBAction func clickMyButton(_ sender: NSButton) { // or anywhere else
self.quantityTextField.isEnabled = false
self.quantityTextField.isEnabled = true
}
Not very sexy but it is reliable
Edit: Just saw it, it solves #Lee's issue
try add this function to your viewController
override func touchesBegan(touches: Set<UITouch>, withEvent event: UIEvent?) {
// I assume your textField call myText
myText. resignFirstResponder()
}
I put a numeric keypad in my app for inputing numbers into a text view, but in order to input numbers I have to click on the text view. Once I do so, the regular keyboard comes up, which I don't want.
How can I disable the keyboard altogether? Any help is greatly appreciated.
The UITextField's inputView property is nil by default, which means the standard keyboard gets displayed.
If you assign it a custom input view, or just a dummy view then the keyboard will not appear, but the blinking cursor will still appear:
UIView* dummyView = [[UIView alloc] initWithFrame:CGRectMake(0, 0, 1, 1)];
myTextField.inputView = dummyView; // Hide keyboard, but show blinking cursor
If you want to hide both the keyboard and the blinking cursor then use this approach:
-(BOOL)textFieldShouldBeginEditing:(UITextField *)textField {
return NO; // Hide both keyboard and blinking cursor.
}
For Swift 2.x, 3.x, 4.x, 5.x
textField.inputView = UIView()
does the trick
If it's a UITextField, you can set it's enabled property to NO.
If it's a UITextView, you can implement -textViewShouldBeginEditing: in its delegate to return NO, so that it'll never start editing. Or you can subclass it and override -canBecomeFirstResponder to return NO. Or you could take advantage of its editing behavior and put your numeric buttons into a view which you use as the text view's inputView. This is supposed to cause the buttons to be displayed when the text view is edited. That may or may not be what you want.
Depending on how you have your existing buttons working this could break them, but you could prevent the keyboard from showing up setting the textView's editable property to NO
myTextView.editable = NO
I have the same problem when had 2 textfields on the same view. My purpose was to show a default keyboard for one textfield and hide for second and show instead a dropdown list.
- (BOOL)textFieldShouldBeginEditing:(UITextField *)textField
method simply did not work as I expected for 2 textfields , the only workaround I found was
UIView* dummyView = [[UIView alloc] initWithFrame:CGRectMake(0, 0, 1, 1)];
myTextField.inputView = dummyView;
myTextField.inputAccessoryView = dummyView;
myTextField.tintColor = myTextField.backgroundColor; //to hide a blinking cursor
This will totally hide the keyboard for a target textField (DropDownList in my case) and show a default one when user switches to the 2nd textfield (Account number on my screenshot)
There is a simple hack to it. Place a empty button
(No Text) above the keyboard and have a action Event assign to it. This will stop keyboard coming up and you can perform any action you want in the handle for the button click
To disable UITextField keyboard:
Go to Main.Storyboard
Click on the UITextField to select it
Show the Attributes inspector
Uncheck the User Interaction Enabled
To disable UITextView keyboard:
Go to Main.Storyboard
Click on the UITextView to select it
Show the Attributes inspector
Uncheck the Editable Behavior
I used the keyboardWillShow Notification and textField.endEditing(true):
lazy var myTextField: UITextField = {
let textField = UITextField()
// ....
return textField
}()
override func viewDidLoad() {
super.viewDidLoad()
NotificationCenter.default.addObserver(self, selector: #selector(keyboardWillShow(_:)), name: UIResponder.keyboardWillShowNotification, object: nil)
}
#objc func keyboardWillShow(_ notification: Notification) {
myTextField.endEditing(true)
// if using a textView >>> myTextView.endEditing(true) <<<
}
private void TxtExpiry_EditingDidBegin(object sender, EventArgs e)
{
((UITextField)sender).ResignFirstResponder();
}
In C# this worked for me, I don't use the storyboard.
In Xcode 8.2 you can do it easily by unchecking state "enabled" option.
Click on the textField you want to be uneditable
Go to attirube inspector on right side
Uncheck "enabled" for State
Or if you want to do it via code. You can simply create an #IBOutlet of this text field, give it a name and then use this variable name in the viewDidLoad func (or any custom one if you intent to) like this (in swift 3.0.1):
override func viewDidLoad() {
super.viewDidLoad()
// Do any additional setup after loading the view.
myTextField.isEditable = false
}
