How to dismiss keyboard in a UIView in iOS?

Question

I put a function in my code like this:

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

where textfield is connect to a UITextField item.

@IBOutlet weak var textfield: UITextField!

but when I run the program, actually I cannot hide it wherever I tap or click. Could you please help me to solve it?

Have you connected ```textfield```'s delegate? – iWheelBuy May 09 '17 at 17:14 — iWheelBuy, May 09 '17 at 17:14

Need to set delegate

override func viewDidLoad() {
    super.viewDidLoad()
    textfield.delegate = self                  //set delegate 
}

Since there is an outlet, why do this in code? Connect the text field's delegate in the storyboard. – rmaddy May 09 '17 at 21:00

try this : override func touchesBegan(touches: Set, withEvent event: UIEvent?) { self.view.endEditing(true) } – KKRocks May 10 '17 at 08:09
