I'm looking to run a CCTintTo on my scenes background layer, but can't seem to get any tint actions to run correctly. I've tried using a CCLayerColor instead of a standard CCLayer, but that had little effect.
After a bit of Googling it seems that CCLayer's don't actually draw anything themselves and instead act more as containers. So what's the best way of drawing a fullscreen rectangle and tilting its colour using cocos2d actions?

I opted not to include any code due to its relative simplicity. Nevertheless, here's what I'm attempting to do:
[self runAction:[CCTintTo actionWithDuration:4 red:255 green:255 blue:255]];
Where self is my CCLayerColor subclass GameLayer. GameLayer is added to my scene like so:
+(CCScene *) scene
{
CCScene *scene = [CCScene node];
GameLayer *layer = [GameLayer node];
[scene addChild:layer];
return scene;
}Expected behaviour here is a 4 second tint duration, resulting in my GameLayer background turning to white. But nothing happens.

Try changing your code like this:
GameLayer *layer = [GameLayer layerWithColor:ccc4(0,0,0,255)];Then, if you're currently overriding the -init method of CCLayerColor, override initWithColor: instead:
- (id)initWithColor:(ccColor4B)color {
if ((self = [super initWithColor:color])) {
[self runAction:[CCTintTo actionWithDuration:4.0 red:255 green:255 blue:255]];
}
return self;
}I think the reason your code isn't working is that by overriding -init, you're missing some of the important stuff that -initWithColor: does, including setting the layer's content size to the screen size. My guess is your action is running now, but since your layer is zero size, you can't see the effects.
