Today I was following this tutorial: http://youtu.be/9rq4P-L-z8U. However, when it came to the part where it showed how to close the keyboard after pressing the button, I followed the instructions, but when I started the simulator, the keyboard simulator never appeared on the screen.
How can I fix this?
This is my code:
class ViewController: UIViewController {
#IBOutlet var TextField: UITextField!
#IBOutlet var Label: UILabel!
#IBAction func ButtonMethod(sender: AnyObject) {
Label.text = TextField.text
TextField.resignFirstResponder()
}
}
#IBAction func ButtonMethod(sender: AnyObject) {
self.view.endEditing(true)
}
This will remove the keyboard from your screen when you press on a button
EDIT: Since your title is different than your question this is the answer:
Uncheck connect hardware keyboard
if when you start edit text box and keyboard is not showing than on simulator functions , go to Hardware->KeyBoard->Connect HardWare KeyBoard and uncheck it!!
otherwise in button action just write
YourTextField.resignFirstResponder = true
may this will help you also check for textfield delegate connected or not

On iOS13 I've noticed that after a textfield is cleared programatically the value for that textfield in the UI tests doesn't update.
In my UI test:
Text is entered into the textfield.
Some action happens which causes my code to clear the textfield (in this case tapping return on the on screen keyboard).
The value of the textfield is checked and it still contains the text that was present before it was cleared.
Here is the code I'm using to clear the textfield:
func clearInput() {
textField.text = nil
}
Here is the check I'm using in my UI test:
XCTAssert((createPasswordPage.passwordSecureTextField.value as? String) == "")
This fails on iOS13 but passes on older versions such as iOS12.
Any idea why this might be happening?
Example:
Code
class PasswordViewController: UIViewController {
#IBOutlet weak var textField: UITextField!
#IBOutlet weak var button: UIButton!
...
#IBAction func buttonTapped(_ sender: Any) {
// Clear the text
textField.text = nil
}
}
UI Test
func testTextClearing() {
let page = PasswordPage()
// Enter text
page.passwordTextField.tap()
page.passwordTextField.typeText("some text")
// Tap button causing text to clear from the textfield
page.button.tap()
XCTAssert((page.passwordTextField.value as? String) == "")
}
My tricky problem is :
I've 2 buttons with 2 UITextView.
Like you know, when I push an UITextView, keyboard appear. Well, this is not what I want.
I want to enable / disable the display's keyboard according a specific #IBAction taped.
The scenario is the following:
- First button (Keyboard icon) allow the user to display the keyboard to type something in one of the UITextView, with a FirstResponder init on the top one.
Second button (REC icon) allow the user to speak and display in pre-selected TextView but without displaying keyboard.
I already known that there is :
isUserInteractionEnabled
and
textViewDidBeginEditing
But it doesn't really fit well and/or fix my issue.
Here a screen to be more explicit (don't give a mind about the third green validate button, it's just for the .POST feature) :
Thanks for any help!
If I understand your problem correctly, You don't want the keyboard to appear when user taps on the textField but rather should come up only when user taps on Keyboard button and should dismiss on tapping other button.
All the posted answers mostly focus only on second part of showing keyboard and dismissing them on tapping button. Whats more tricky is preventing keyboard from appearing in when user taps on textField :)
Possible solutions you can try and their cons:
Solution 1:
Try setting textfield isEnabled = false sure this will prevent keyboard from appearing when user taps on textField but guess what Keyboard will not appear even on calling textfield.becomeFirstResponder() ahhh trouble :)
Solution 2:
implementing textFieldShouldBeginEditing of UITextField delegate and returing true or false based on whether used tapped on button or textField itself.
Sure it works but you will need to figure out way to tell textFieldShouldBeginEditing why was it triggered because of button or because of touch on textField again complications.
My Solution:
Use 2 textFields. One disable user interaction forever and use another textField which will never appear to user but will take care of showing keyboard when required.
Enough talk lets code :)
Step 1:
Lets say your textField which appears on screen is called textField
textfield.isEnabled = false
This will ensure whatever you do keyboard will not appear for this keyboard.
Step 2:
Create a temp textField of frame zero (which user can never tap :P )
tempTextField = UITextField(frame: CGRect.zero)
tempTextField.delegate = self
self.view.addSubview(tempTextField)
Step 3:
Now when user taps on show keyboard button, make your temp textField first responder
tempTextField.becomeFirstResponder()
and when user taps on other button resignFirstResponder for tempTextField.
tempTextField.resignFirstResponder()
Step 4:
But wait when user types nothing appears on my textField. Wait simply implement
func textField(_ textField: UITextField, shouldChangeCharactersIn range: NSRange, replacementString string: String) -> Bool {
if textField == tempTextField {
self.textfield.text = (self.textfield.text ?? "") + string
}
return true
}
EDIT:
You don't really need two textFields, you can achieve the same with a UILabel and UITextField as well. I chose UITextField as I am not sure what are other requirements of yours!
Problem fixed. Hope it helps :)
Something like this should work:
class MyViewController: UIViewController, UITextViewDelegate {
#IBOutlet var yourTextView: UITextView
override func viewDidLoad() {
super.viewDidLoad()
yourTextView.delegate = self
}
#IBAction func showKeyboard(_ sender: UIButton) {
self.yourTextView.becomeFirstResponder()
}
#IBAction func hideKeyboard(_ sender: UIButton) {
self.yourTextView.resignFirstResponder()
}
}
You say
But it's not really working in my case.
Why?
You can disable the textfields interaction with (swift 3):
textField.isUserInteractionEnabled = false
Next, when you click on the keyboard button you can reenable the interaction so when the user click on one of the textfield the keyboard opens.
On the keyboard dismiss (you can see the UIKeyboardWillHideNotification callback notification) you can set the interaction to false.
function to dismiss KeyBoard when button is clicked:
#IBAction func hideKeyboard() {
textView.resignFirstResponder()
}
function to get keyboard to show up:
#IBAction func showKeyboard() {
textView.becomeFirstResponder()
}
Just copy and paste simple code for you accessory button embedded with keypad
func addKeyboardToolbar() {
let ViewForDoneButtonOnKeyboard = UIToolbar()
ViewForDoneButtonOnKeyboard.sizeToFit()
let button = UIButton.init(type: .custom)
button.setImage(UIImage.init(named: "login-logo"), for: UIControlState.normal)
button.addTarget(self, action:#selector(doneBtnfromKeyboardClicked), for:.touchUpInside)
button.frame = CGRect.init(x: 0, y: 0, width:UIScreen.main.bounds.width, height: 30) //CGRectMake(0, 0, 30, 30)
let barButton = UIBarButtonItem.init(customView: button)
ViewForDoneButtonOnKeyboard.items = [barButton]
postTextView.inputAccessoryView = ViewForDoneButtonOnKeyboard
}
#IBAction func doneBtnfromKeyboardClicked (sender: Any) {
self.contentView.endEditing(true)
}
This is a very basic question but I'm not sure what the problem is. I'm trying to make a simple "hello world" program where the user inputs what they want into the textfield and whatever they enter goes into the label. However, nothing seems to be happening and I'm unsure why since my push function worked exactly how I expected it to.
import UIKit
class ViewController: UIViewController {
#IBOutlet var PopUp: UITextField!
#IBOutlet weak var HelloWorld: UILabel!
#IBAction func Push(_ sender: UIButton) {
PopUp.isHidden = false
PopUp.text = "hello World"
}
#IBAction func send(_ sender: UITextField) {
HelloWorld.text = sender.text
}
}
Based on the code you provided, func send is an unknown to me, as to whether or not it is even firing. func send might be called, might not, either way, it is strange to see a _ sender: UITextField for an IBAction.
What event are you firing related to the UITextField? Are you trying to update your HelloWorld UILabel as the user types in the UITextfield?
To update your UILabel with whatever has been typed in your UITextField, you just need a UIButton Touch Up Inside IBAction. I think you can delete IBAction func send completely, unless you are trying to update the UILabel as the user types in the UITextField. Make sure you remove the IBAction Outlet from your Storyboard if I am correct about this point.
Based on the code you provided the Push func does not set text in your UILabel. I am assuming Push is an UIButton Touch Up Inside IBAction. You can set your HelloWorld UILabel text, in func Push, you do not need to use the sender of the event, try this and you will see the HelloWorld UILabel text populated:
#IBAction func Push(_ sender: UIButton) {
//PopUp.isHidden = false //why are you doing this? the UITextField PopUp should already be visible if you are typing text into it, so this code is superfluous as the value of PopUp.isHidden is already false
HelloWorld.text = PopUp.text
PopUp.text = "hello World"
}
If you are trying to have your UILabel display the text as you type into the UITextField you should clarify your question. And if it is the case you will need to make your UIViewController a UITextFieldDelegate
Here is the one way of approach :
override func viewDidLoad() {
super.viewDidLoad()
PopUp.addTarget(self, action: #selector(textFieldDidChange(_:)), for: .editingChanged) // when textfield is edited this will call
}
func textFieldDidChange(_ textField: UITextField) {
HelloWorld.text = textField.text
}
I create Start_button and make #IBOutlet and #IBAction
#IBOutlet weak var Start_button: UIButton!
#IBAction func Start_button(sender: AnyObject)
Now, i want hide button after click. I try this, but this don't work:
#IBAction func Start_button(sender: AnyObject)
{
Start_button.hidden = true;
}
Error message:
fatal error: unexpectedly found nil while unwrapping an Optional value
(lldb)
How i can hide this button?
Thanks for helping!
Its nil because you probably haven't connected it from your storyboard/nib. You need to connect the outlet, you can't just create an outlet in code and expect it to be connected to the visible element. The same goes for your action. #IBOutlet / #IBAction stands for Interface Builder Outlet/Action, which means you have to connect them in Interface Builder.
Also its better if your action uses the sender, and not a local variable (when its pointing to the same thing). And you shouldnt use ;at the end of the line.
#IBAction func Start_button(sender: UIButton) // Change to UIButton
{
sender.hidden = true
// OR
// (sender as! UIButton).hidden = true
}
#IBAction func button_nameA(sender: AnyObject) {
// show hidden buttons
self.Target_Object.hidden = false
}
So when you click the A buttons its automaticly send to you target and in target also you have to hide button if you working single view app
I'm running this code within a ViewController class that contains UIViewController and SettingsViewDelegate. The View Controller scene contains a text view that has a scroll bar.
#IBOutlet weak var tvEditor: UITextView!
override func viewDidLoad() {
super.viewDidLoad()
// Hide keyboard via swipeDownGestureRecognizer.
let swipeGesture: UISwipeGestureRecognizer = UISwipeGestureRecognizer (target: self, action: "hideKeyboard")
swipeGesture.cancelsTouchesInView = false
UISwipeGestureRecognizerDirection.Down
}
func hideKeyboard() {
tvEditor.resignFirstResponder()
}
When I run my project in the iOS Simulator/device, the keyboard does not respond to a downward swipe. I change the orientation of my device to landscape, and then back to portrait, which is when the keyboard disappears. Can someone please tell me where I'm going wrong?
First, Please add swipeGesture to your viewcontroller.
And...
func hideKeyboard() {
self.view.endEditing(true)
}
It'll works fine for your project.
Hope it'll help you.
