Creating a fullscreen UIView programmatically?

I am trying to programmatically create a new UIView for loading and set parameters in code. Basically the view will be very simple. Literally all I need is an UIView that is fullscreen and has an image in the middle. I want this so that I can call a global function whenever anything is loading and show a white screen with a loading image. I do not want to make the view inside the XIB because I will have to add it to dozens of existing XIB's.

I have read a few posts on here most of them outdated, what is the simplest way I can create a fullscreen UIView with a solid color. Im sure I can figure out the image part myself.
