Making Apple's not available UIView, like in the E.g.

Hello everybody,
I'm working in a project, and I needed to use this View's, to make a greater experience.
But Apple doesn't provide any source for them, I couldn't find any how-to's, neither they're available in the Xcode. So it's a personalized UIView.
I hope if someone could help me, like the name of this UIView or if you have it. I Would appreciate to talk more about this.
The examples are in the Imgur, because I thought it was better to see.
