How to set the background image according to screen size?

Question

I want to set an image according to screen size. I've been going through many codes on it but I've not found a working solution yet. I'm using Xcode 5.1.1 and Iphone Retina 4inch. Whenever I add my background image, it becomes huge and goes out of screen size. Kindly help me.

Use the code from Anbu's answer to get the screen height and set the image to aspectFit to avoid it from getting huge and out of bounds:

yourImageview.contentMode = UIViewContentModeScaleAspectFit;
yourImageview.clipsToBounds = YES;
