How can I connect a SKScene to a UIViewController? - ios

Question

In the main ViewController class usually called 'GameViewController' there's this part in the code that can use 'GameScene' classes and you can add Nodes or Labels. This is the part in 'GameViewController.m'
- (void)viewDidLoad
{
[super viewDidLoad];
// Configure the view.
SKView * skView = (SKView *)self.view;
skView.showsFPS = YES;
skView.showsNodeCount = YES;
/* Sprite Kit applies additional optimizations to improve rendering performance */
skView.ignoresSiblingOrder = YES;
// Create and configure the scene.
GameScene *scene = [GameScene unarchiveFromFile:#"GameScene"];
scene.scaleMode = SKSceneScaleModeAspectFill;
// Present the scene.
[skView presentScene:scene];
}
I created another UIViewController class called 'ViewController' and a SKScene class called 'testSceneClass'. I tried doing this in 'ViewController.m' class:
- (void)viewDidLoad
{
[super viewDidLoad];
//[ViewController addChild: test];
// Configure the view.
SKView * skView = (SKView *)self.view;
skView.showsFPS = YES;
skView.showsNodeCount = YES;
/* Sprite Kit applies additional optimizations to improve rendering performance */
skView.ignoresSiblingOrder = YES;
// Create and configure the scene.
testSceneClass *scene = [testSceneClass unarchiveFromFile:#"testSceneClass"];
scene.scaleMode = SKSceneScaleModeAspectFill;
// Present the scene.
[skView presentScene:scene];
}
But it gives me the error "No known class method for selector 'unarchiveFromFile'" And I copied pretty much everything from the SKScene and UIViewController so I don't know what is wrong. But when I run it, it crashes and this is the reason:
reason: '-[UIView setShowsFPS:]: unrecognized selector sent to
instance
When I add a Exception Breakpoint it showed up on this line.
skView.showsFPS = YES;
Then when I comment it, it shows a error on the next line, you can look at it in the 'ViewController.m' file I showed above. After I commented all those, an error showed up on this line:
NSData *data = [NSData dataWithContentsOfFile:nodePath
options:NSDataReadingMappedIfSafe
error:nil];
and so on...
Any help?? (Sorry I added so much lol)
