问题
In the Messages app on my iPhone (iOS 8.0.2), when you are composing a message and you click on the camera icon to insert an image, a "slide-up" menu appears from the bottom. It contains a few buttons, along with recently-taken pictures I could insert into my message.
What is this menu called?
Is it available through a native class already?
How are the images nested inside the menu?
Are there any helpful other helpful resources for implementing it?
Thank you!

It's called a UIActivityViewController. You can read more about it here:
