This comment is confusing to someone who's reading this code for the first time.
Please be more descriptive. 

Also, since this is a string, it needs to be named ...String, so
copiedURLString.

Depending on your class comment's descriptiveness, you might need to make this
more descriptive.

Acknowledged.

+- (UIView*)createActionsView:

[stkhapugin, 2017/05/04 13:12:08]

This should be:

Done.

[stkhapugin, 2017/05/04 13:12:09]

This method must return a UIView. Also, if you need to pass down the anchor, you
need to rename your method like so:
-
(UIView*)newOpenCopiedURLViewWithAnchorThatINeedForReasons:(NSLayoutAnchor*)anchor

as explained below, please don't pass the constraint array down.

[lody, 2017/05/05 17:05:43]

This does not create a single view, so returning one would make no sense. I
changed the name to be more accurate (using section rather than view).

[stkhapugin, 2017/05/04 13:12:08]

This potentially gives you a small performance bump, but makes the code much
less readable as you're passing this array around everywhere. It's also not the
best idea to pass a mutable array around. I strongly suggest rewriting in a way
where you never pass around constraint arrays. Instead:

- in this method, set up all constraints between |self| and its immediate
subviews
- inside the helper methods, set the constraints related to the created subview

[lody, 2017/05/05 17:05:43]

As discussed, the passing around of constraints is somewhat necessary for icons.
I tried a method that we discussed, please check what you think of it.

All of this logic belongs to controller layer, not the view. You should instead
expose a set of APIs that tells the view to:

1. show or hide the copied URL section
2. tell this view to use certain strings for openCopiedURLTitleLabel and
copiedURLLabel
