SKScene iPad height width reversed - ios

Question

I am trying to fill my SKScene with tiles, in an iPad app that only supports landscape mode. Within the scene I detect h & w as such:
int h = [UIScreen mainScreen].bounds.size.height;
int w = [UIScreen mainScreen].bounds.size.width;
Unfortunately, the dimensions sent back are the reverse of what they need to be. There are lots of topics in SO discussion this problem within the content of a view controller or a view, and the solution seems to be to detect screen size in viewWillAppear, not in viewDidLoad. This does not seem to be a valid solution for SKScenes, however.
Any suggestions?

Answer 1

Try, not using viewDidLoad and use this
- (void)viewWillLayoutSubviews
{
[super viewWillLayoutSubviews];
SKView * skView = (SKView *)self.view;
if (!skView.scene) {
skView.showsFPS = YES;
skView.showsNodeCount = YES;
SKScene * scene = [MyScene sceneWithSize:skView.bounds.size];
scene.scaleMode = SKSceneScaleModeAspectFill;
// Present the scene.
[skView presentScene:scene];
}
}

Answer 2

It doesn't make sense to initialize the scene in the layout handler. Resize the scene in the layout handler. (That's what it's for.)
#implementation SGOMyScene
{
SKScene *scene;
}
- (void)viewDidLoad
{
[super viewDidLoad];
SKView *skView = (SKView *)self.view;
skView.showsFPS = YES;
skView.showsNodeCount = YES;
scene = [SGOMyScene sceneWithSize:skView.bounds.size];
scene.scaleMode = SKSceneScaleModeAspectFill;
[skView presentScene:scene];
}
- (void)viewWillLayoutSubviews
{
[super viewWillLayoutSubviews];
SKView *skView = (SKView *)self.view;
scene.size = skView.bounds.size;
}
Your scene should implement - (void)didChangeSize:(CGSize)oldSize to move everything into the right place.
Hooray, now your game handles device rotations too.
