Touches began Func not working on scrollView

I don't understand : can't make the text disappeared when the user tap the screen in view inside scroll view

Which view ? It seems to contain a button and an image only ; unless there is also a textField not shown on the image ?

Where is the text ? Inside a textField ? Where is it declared ?

elskroll is a UIScrollView

So with,

elskroll.endEditing(true)

elskroll resigns as first responder, but that does not hide anythings (except keyboard is visible) ; so even if there is a textField inside the view, that will not make the text disappear

Why would it call textFieldShouldReturn(_ textField: UITextField)

Why would it make the text diapeear ?

-> Do you mean clear the text field ? : then set text to "" : myTextField.text = ""

-> Do you mean hide it ? : then set isHidden true : myTextField.isHidden = true

Note: have you a typo:

overridefunc touchesBegan(_ touches: Set, with event: UIEvent?) {

vs

override func touchesBegan(_ touches: Set, with event: UIEvent?) {

Seems you have not copied the exact code but retyped it ?

override func touchesBegan(_ touches: Set, with event: UIEvent?) {
        elskroll.endEditing(true)
    }
    func textFieldShouldReturn(_ textField: UITextField) -> Bool {
        textField.resignFirstResponder()
        return true
    }

elskroll is the UIScrollView

@IBOutletvar elskroll: UIScrollView!

i have the Default View, inside a ScrollView and inside of a View

as the image shows

Sorry, you do not answer my questions. That only repeats the original post.

Where is the text you want to make disappear ? Inside a textField ? Where is this textField declared ?

What is the Default View you mention ?

elskroll is the UIScrollView

@IBOutlet var elskroll: UIScrollView!

Yes, I understood this, but that does not answer the questions:

elskroll resigns as first responder, but that does not hide anythings (except keyboard is visible) ; so even if there is a textField inside the view, that will not make the text disappear

• Why would it call textFieldShouldReturn(_ textField: UITextField)
• Why would it make the text diapeear ?

Where is the text you want to make disappear ? Inside a textField ? Where is this textField declared ?

i want the keyboard to disappear when the user tap the screen (user only can see the keyboard when tap UITextField

What is the Default View you mention ?

maybe it was silly to mention Default 'view' what i meant for that is when you create a 'View Controller' comes with a blank screen and if you see it in the 'Document Outline it says

View Controller Scene

View Controller

View

Safe Area

First Responder

Exit

Why would it call textFieldShouldReturn(_ textField: UITextField)

i don't know i as far as i know i should put those two to make the text disappear and call it back (i read it in some place and always do it)

Why would it make the text disappear ?

i just want the keyboard to disappear not text

OK. What you want is the keyboard to disappear, but not the text with the code you've shown. Your original post was not clear.

Question: why did the keyboard appear ? Probably because you typed in a textField (let's name it myTextField) defined with an IBOutlet.

To hide the keyboard, you should call

myTextField.resignFirstResponder().

You could also call

textFieldShouldReturn(myTextField)

But not very useful

Usually, touch events on a UIScrolView are not forwarded to the encosing UIViewController.

(You know UIScrollView needs to handle touch events for scrolling.)

Have you checked your `touchesBegan(_:with:)` is ever called?

If no (it's the expected behavior as for now), you need to make some extra effort to detect touches on the UIScrollView.

func textFieldShouldReturn(_ textField: UITextField) -> Bool { // All paths through this function will call itself

do i need to call every UITextField?

because i have several texts fields

like you said

To hide the keyboard, you should call

myTextField.resignFirstResponder().

You could also call

textFieldShouldReturn(myTextField)

Heres all my code to make it clear

thanks i did some research and got it working

override func viewDidLoad() {
        super.viewDidLoad()
        iconClick = true
        
        // Do any additional setup after loading the view.
       
        let recognizer = UITapGestureRecognizer(target: self, action: #selector(self.touch))
        recognizer.numberOfTapsRequired = 1
        recognizer.numberOfTouchesRequired = 1
        elskroll.addGestureRecognizer(recognizer)
        
        
        
        
    }
    
    @objc func touch() {
        self.view.endEditing(true)
    }
