how to hide keyboard after clicking return in swift

Question

I want to hide the keyboard after clicking the return button, and I have searched on website and wrote the same code as it shows on the internet. However, the keyboard still didn't hide. I don't know why?

this is the design

this is the code

Answer 1

I think like @paulvs said is to set the delegate

so drag the text field on the storyboard to the "donut" at the top of the screen and select delegate

then create and IBOutlet for the text field by being on the storyboard and then tapping the assistant editor...it looks like two overlapping circles Control drag the text field to your viewcontroller and make sure it is on Outlet and then name it textField

Next set the delegate by setting it equal to itself so

textField.delegate = self

then create a delegate function (should auto fill as you type) but it is func textfieldshouldreturn

inside that func do this

textField.resignfirstresponder()

then return true

Answer 2

try to confirm: 1. inherit from UITextFieldDelegate; 2. set the current view controller self as delegate; 3. return false at the overrided func textfieldshouldreturn that you called.
