Understanding iPhone 5/6 resolution on image.xcassets

Question

As the title says, I'm still confused to understand how image.xcassets handles the iPhone 5/6 images. Let me explain better:

example

This is my MENU_EMPTY_LIST file in image.xcassets. I've been looking for an answer here in stackoverflow and I found this:

1x images are for the original iPhone through the 3GS - 'standard' resolution devices (3.5" screens)
2x images are for the iPhone 4, 4S (3.5" Retina screens) and also iPhone 6.
Retina 4 2x are for the iPhone 5 and 5s (4" Retina screens)
3x images are for the new iPhone 6+ (5.5" super-Retina [3x] screen)

This helped me a lot but my question is: what if the image set is a background (in short, an image covering all the screen)? How can I handle the different screen size? What do I have to put into the "2x" square? An iPhone 4/4S image or iPhone 6?

only one problem is iPhone 4 and iPhone 6 taking same @2x images.

So, If you want to set perfect image for all the devices then you have to try following code :

if([[UIScreen mainScreen]bounds].size.height==480)
{
    login_bg.image=[UIImage imageNamed:@"i4_login.png"];
}
else if ([[UIScreen mainScreen]bounds].size.height==568)
{
    login_bg.image=[UIImage imageNamed:@"i5_login.png"];
}
else if ([[UIScreen mainScreen]bounds].size.height==667)
{
    login_bg.image=[UIImage imageNamed:@"i6_login.png"];
}
else if ([[UIScreen mainScreen]bounds].size.height==736)
{
    login_bg.image=[UIImage imageNamed:@"i6+_login.png"];
}
else if ([[UIScreen mainScreen]bounds].size.height==1024)
{
    login_bg.image=[UIImage imageNamed:@"ipad_login.png"];
}

So I don't have to use image.xcassets in that case? – user3582537 May 12 '15 at 10:43
Yes! Thanks I forgot to answer :) I just was looking a way to organize the folders and files with this new method :) – user3582537 May 12 '15 at 11:04
This would be much nicer to read if it were switch((NSInteger)[[UIScreen mainScreen]bounds].size.height) ...long if/else/else chains are ugly – Jef May 12 '15 at 14:21
It's Work for you ? Please accept my answer @user3582537 – Jay Bhalani Sep 19 '15 at 13:22
