SKColor clearColor returning a black color instead?

Question

I have setup my SKScene the following way during initiation:

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


             


        

Answer 1

After try many things, this worked for me

skView.allowsTransparency = true
skView.backgroundColor = UIColor.clear
view.addSubview(skView)
floatingCollectionScene = BubblesScene(size: skView.bounds.size)
floatingCollectionScene.backgroundColor = UIColor.clear
floatingCollectionScene.scaleMode = .resizeFill
skView.presentScene(floatingCollectionScene)

Answer 2

iOS 8 supports transparency:

skView.allowsTransparency = YES;

Answer 3

Setting it to clear is working correct, resulting in no colour, so black.

Set to any colour you like via

self.backgroundColor = [SKColor colorWithRed:0.15 green:0.15 blue:0.3 alpha:1.0];
