swift iOS hide keyboard away

To hide the keyboard away from screen by tapping other part, we need a command to do that.

By keying in touchesBegan, the IDE will automatically overwrite this

override func touchesBegan(touches: Set<UITouch>, withEvent event: UIEvent?) { 

        self.view.endEditing(true) 

 or

view.endEditing(true)

        

    }

func touchesBegan is called when user tap the screen at outside textboxes.

If you keyboard has a return key and wanted to hide the keyboard after user tap on return key:

 func textFieldShouldReturn(textField: UITextField!) -> Bool {                textBoxField.resignFirstResponder()       

return true    

}

textBoxField is the textbox object
