How can I create a button with isHidden code and get UIAlert when it be pressed? and be visible after that - swift 4

How do I create an hidden button? When I press the button, it creates a UIAlert and asks if I want to buy the product. And when I buy the product, the button will be visible?
If a button is hidden, it is not clickable. Instead, you may want to create a "clear" button. When you press the button, popup the UIAlert and make the button not clear.

keeping iphone keyboard on screen and change its enter button name

i want to show my keyboard on screen , whenever a view is shown i.e my login screen..
and i also want to change the name of enter button to Login button.
please help
To change the return key value, change the UIReturnKeyType enum (UITextInputTraits).
If you want the keyboard to show on the screen when it loads, you need to hook up your UITextField to the delegate and include UITextFieldDelegate in your header file. (That is assuming you are using a UITextField.)
Then call:
[textField becomeFirstResponder]
in your viewWillAppear method to give focus to the UITextField which then raises the keyboard.

UITextFieldDelegate != IBAction backgroundTap

The scope of this question is IPhone 3.1 sdk (app running in simulator still)
I have a table view that has a cell with a UITextField in that cell. The table view is grouped, and has one section with just a couple fields. Im NOT using IB so backgroundTap is out of the question (as far as i can tell at least). When i click the text field, keyboard shows. Hiding it is still troublesome. Ive pulled the UITextFieldDelegate into the mix to hide the keyboard but the textFieldShouldEndEditing method doesnt seem to fire when the background is tapped (when i mean background, im tapping outside of the grouped table view section). First off, should it?
textFieldShouldReturn fires with no problem and i can resign at this point but shouldnt i be able to resign if focus shifts away from that control?
Any help is much appreciated

Generally you'll only stop editing a field when you:
hit the "Done" or action button on the keyboard
begin editing another field
exit the view
have another button on screen that removes focus
From any of these, you can call -[textField resignFirstResponder] to dismiss the keyboard and call your -textFieldShouldEndEditing: method. There's no reason that just tapping on a non-active part of the screen should dismiss the keyboard.
