Transition from ViewController to SKScene - ios

Question

I'm currently making a game in which the main game is a SKScene however the menu is a UIViewController. I have a button which when tapped should transition from the menu to the SKScene. What code should i write in the IBAction?
I'm running xcode6 beta 5. If that changes anything.

Answer 1

Simply load view controller from the storyboard. And after it present it.
UIStoryboard *storyboard = [UIStoryboard storyboardWithName:#"Main_iPhone" bundle:nil];
MyViewController *lcvc = (MyViewController*)[storyboard instantiateViewControllerWithIdentifier:#"MyViewController"];
lcvc.modalPresentationStyle= UIModalPresentationCustom;
[self presentViewController:lcvc animated:YES completion:nil];

If you have only one view controller that contains a button and will later present the SKScene, you can implement an IBAction similar to the following:
Objective C
- (IBAction) buttonPressed:(UIButton *)button
{
// Remove button from the view
[button removeFromSuperview];
// Configure the view.
SKView * skView = (SKView *)self.view;
skView.showsFPS = YES;
skView.showsNodeCount = YES;
// Create and configure the scene.
SKScene * scene = [MyScene sceneWithSize:skView.bounds.size];
scene.scaleMode = SKSceneScaleModeAspectFill;
// Present the scene.
[skView presentScene:scene];
}
Swift
#IBAction func buttonPressed(button:UIButton)
{
// Remove button from the view
button.removeFromSuperview()
if let scene = GameScene.unarchiveFromFile("GameScene") as? GameScene {
// Configure the view.
let skView = self.view as SKView
skView.showsFPS = true
skView.showsNodeCount = true
/* Sprite Kit applies additional optimizations to improve rendering performance */
skView.ignoresSiblingOrder = true
/* Set the scale mode to scale to fit the window */
scene.scaleMode = .AspectFill
skView.presentScene(scene)
}
}
If you have two view controllers, one containing the button and the other that will present your SKScene, then you don't need an IBAction. You can simply create a segue from the button to your game view controller. From the storyboard, right-click (or control-click) on the button and drag from the Triggered Segues's action to the game view controller and release the mouse/trackpad button.
