objective c - Naming convention for iPhone 5 images?

Question

I am working on an app that would be for iPhone 5 and lower.

for images I am using this code

CGRect mainFrame = [[UIScreen mainScreen] bounds];

int imgIndex = arc4random() % 10 + 1;

if(mainFrame.size.height > 480)
    [pBackgroundImageView setImage:[UIImage imageNamed:[NSString stringWithFormat:@"dreams 1136x640 %d.jpg",imgIndex]]];
else
    [pBackgroundImageView setImage:[UIImage imageNamed:[NSString stringWithFormat:@"dreams_960x640_%d.jpg",imgIndex]]];

but I am not satisfied with it.

is there any specific naming convention for iphone 5 images?

Thanks in advance Mano

Default-568h@2x.png this would be the launch image you need, you need to add -568h@2x to the end of all your iPhone 5 images, but there have been issues with the naming convention.

I found doing it like this has helped.

   [pBackgroundImageView setImage:[UIImage imageNamed:(IS_PHONE5()) ? @"myimage-568h@2x.png" : @"myimage.png"]];

The issue is it doesn't pick the -568h@2x up but this is the way it should be. to get the IS_PHONE5 variable add

   #define IS_PHONE5() ([UIScreen mainScreen].bounds.size.height == 568.0f && [UIScreen mainScreen].scale == 2.f && UI_USER_INTERFACE_IDIOM() == UIUserInterfaceIdiomPhone)

Thought this may help anyone wondering about supporting high resolution phones and iPhone 5
