Background Images in SpriteKit

I am creating a game in SpriteKit and having trouble using background images in my game. I think the problem is that the image has to be the exact resolution of the device otherwise it won't show up. My game is universal so I need it to work with all devices and screen sizes. The way it is now the background shows up black on every device except a normal resolution iPad. I believe this is because that is the resolution of the image. So I want to add on an image that is the resolution of an iPhone but i don't know how to name it so that it would work. How would I go about this? Thanks!

- (void)didMoveToView:(SKView *)view
{
    if (!self.contentCreated)
    {
        [self createSceneContents];
        self.contentCreated = YES;
    }
}

- (void)createSceneContents
{
    self.backgroundColor = [SKColor whiteColor];
    self.scaleMode = SKSceneScaleModeAspectFill;



    SKSpriteNode *bgImage = [SKSpriteNode spriteNodeWithImageNamed:@"bg"];
    [bgImage setAnchorPoint:CGPointZero];
    [self addChild:bgImage];
}

For some reason it only works on a non retina iPad the screen shows up black on all others

Having the wrong resolution doesn't cause an image to just not show up. Something else must be wrong. Show your code. - Mick MacCallum

Essentially this is all you need... 

-(id)initWithSize:(CGSize)size {
    if (self = [super initWithSize:size]) {

        // make your background here i.e.
        _background = [SKSpriteNode spriteNodeWithImageNamed:@"bg"];
        [_background setAnchorPoint:CGPointZero];
        [self addChild:_background];

    }
    return self;
}
