What is the default behavior for a UITextField Return Button?
I am relatively new to iOS programming, and have been curious about a pretty common UITextField delegate function.
In the developer documentation for optional func textFieldShouldReturn(_ textField: UITextField) -> Bool it states:
Return Value true if the text field should implement its default
behavior for the return button; otherwise, false.
I am curious as to what the default behavior for a return button is? In what cases would I return true, or false?

If you want to hide the keyboard when the user clicks return button then
return true
otherwise default is false , the logic depends on your UX of whether you want the keyboard visible all time or not

So anytime you call resignFirstResponder in the text field inside the delegate function, you should return true, and there really isn’t any other default behavior”?
– D. Pratt
Nov 21 '18 at 14:09
not necessarily astextf.resignFirstResponder()/view.endEditing(true)will hide it anyway

This answer is incorrect. The return value has no effect on the display of the keyboard.

Nov 21 '18 at 14:19
That's kind of the source confusion, since (as far as I know) you can't hide the keyboard without calling resignFirstResponder within the delegate function, or by calling endEditing on the view; so it almost seems like the return is pointless?
