i'm facing this problem on iOS(objective-c, not swift). I load a background image from images.xcassets and it displays properly on iOS 8, but not on iOS 7. Have anyone faced this problem before ?

This is the code i'm using:

    SKSpriteNode *background = [SKSpriteNode spriteNodeWithImageNamed:@"xxx"];
    background.position = CGPointMake(CGRectGetMidX(self.frame), CGRectGetMidY(self.frame));
    [self addChild:background];

There are also differences in layouts (i'm not using xibs), but the first step is to solve the background :).

Below are the screenshots from ios 7 % ios 8. enter image description here

Here is a screenshots with images.xcassets:

Seems that ios 7 doesn't recognize that your app is launching in landscape mode so the frame is initialized with the portrait dimensions. I solved this with the following method :

- (CGSize)screenSize {
    CGSize screenSize = [UIScreen mainScreen].bounds.size;
    if ((NSFoundationVersionNumber <= NSFoundationVersionNumber_iOS_7_1) && UIInterfaceOrientationIsLandscape([UIApplication sharedApplication].statusBarOrientation)) {
        return CGSizeMake(screenSize.height, screenSize.width);
    }
    return screenSize;
}

You can find out more by searching for 'orientation-dependency' in iOS 8. Hope this will be usefull for you too.
