03-12 A Look at the Other Two Delegates

The emoji and colorizer text fields
have some minor differences in behavior.

For example, in the emoji text field,

if there's text,
it clears when editing begins.

So it's not possible to edit existing
text after you switch to a different

text field.

Also, the return key in the emoji
text field doesn't hide the keyboard.

The colorizer doesn't clear
text when editing begins.

So it's possible to edit existing texts.

And in the colorizer text field,
the return key does hide the keyboard.

So, given what you know
about the two delegates and

the protocol, which methods do you
think the two delegates implement?
