hide keyboard for text field in swift programming language

Question

I have little experience in Objective-C. I want to hide the keyboard for a text field using the Swift programming language.

I also tried this

func te         


        

Answer 1

Just override the UIViewController method called "touchesBegan" and set endEditing to true. Just like this:

override func touchesBegan(touches: NSSet!, withEvent event: UIEvent!) {
    self.view.endEditing(true)
}

Answer 2

First you need to set delegate for your textfield then you need to include resignFirstResponder() to hide keyboard when press return button of keybaord.

 func textFieldShouldReturn(textField: UITextField!) -> Bool // called when 'return' key pressed. return NO to ignore.
 {
   textField .resignFirstResponder()
   return true;
 }

Answer 3

You can try this code to have the "return" key execute code.

func textFieldShouldReturn(textField: UITextField) -> Bool{
    textField.resignFirstResponder()
    performAction()
    return true;
}

func performAction(){

//execute code for your action inside this function

}

Hope this can help you.

Answer 4

UIApplication.sharedApplication().sendAction(#selector(UIResponder.resignFirstResponder), to:nil, from:nil, forEvent:nil)

Answer 5

when you call your UIAlertController, place condition in the completion handler if you'd like to hide the keyboard.

self.present('nameOfYourUIAlertController', animated: true, completion: {
    if condition == true {
        'nameOfYourUIAlertController'.textFields![0].resignFirstResponder()
    }
})

This works great for me.

Answer 6

In order to hide the keyboard when you pressed a button, you need to use the following function.

self.view.endEditing(true)

This works when a button is pressed.

Hope this helps someone out there.
