How can i switch from SKScene to UIView - uiview

I'm using Sprite kit framework to create a game.
My first scene is MyScene.My Scene is a menu, but i want when is clicked on start to switch to the first view from the story board.
This is the way i switch to another SKScene
Scene001 *start = [[Scene001 alloc] initWithSize:self.size];
SKTransition *reveal = [SKTransition fadeWithColor:[UIColor clearColor] duration:0.5];
[self.scene.view presentScene: start transition: reveal];
Now the question is how to switch to the storyboard scene and vice versa.

I know this is old but just incase someone comes across it and needs an answer:
What I did in my game was make my GameViewController be a delegate of the SKScene. When the user is finished in the SKScene, I called my delegate function in the GameViewController which simply does a performSegueWithIdentifier.
Your viewController that creates your scene has can run segue's. So you need a way to get back to it from your SKScene. Simply make your SKScene a delegate and when your viewController creates it, set the delegate. Then when you want to switch, call the delegate function.
This is my GameViewController that creates my scene:
- (void)viewWillAppear:(BOOL)animated {
SKView * skView = (SKView *)self.view;
if (!skView.scene) {
MyScene *scene = [MyScene sceneWithSize:self.view.bounds.size];
scene.delegate = self;
[skView presentScene:scene];
}
}
// A delegate function
- (void)onExitGame {
[self performSegueWithIdentifier:#"GoToNextScene" sender:self];
}
Then from my MyScene when you're ready to switch the storyboard call the delegate function:
if (self.delegate) {
self.delegate.onExitGame();
}

iOS delegate issue when use it for second time

I am not an experienced app developer, I am modifying an obj c spriteKit game. The concept that I need to implement is, when the user clicks a button in the menu scene (SKScene) "talk" to the navigation controller and show another storyboard who they gave me.
For this I use a delegate from the scene, in order to "talk" to the gameview controller's navigation controller and reference the other storyboard.
Everything works, but when from the starting scene(EndGameScene in the code) the user goes to the gamescene and back then it does not work. And there is no error message!
GameViewController.m
SKView * skView = (SKView *)self.view;
skView.ignoresSiblingOrder = YES;
_scene = [[EndGameScene alloc] initWithSize:self.view.frame.size];
_scene.scaleMode = SKSceneScaleModeAspectFill;
self.scene.delegate = self;
// Present the scene.
[skView presentScene:_scene];
...
//delegation method
-(void)showDifferentView {
UIStoryboard *storyboard = [SettingsViewController settingsStoryBoard];
SettingsViewController *controller = [storyboard instantiateViewControllerWithIdentifier:SettingsControllerStoryboardIdentifier];
[self.navigationController pushViewController:controller animated:YES];
self.navigationController.navigationBarHidden = NO;
}
GameScene.m
-(void)backToHomePage{
[self removeAllChildren];
[self removeAllActions];
[self removeFromParent];
SKScene *endGameScene = [[EndGameScene alloc] initWithSize:self.size];
endGameScene.scaleMode = SKSceneScaleModeAspectFill;
GameViewController *gameVC = [[GameViewController alloc] init];
endGameScene.delegate = gameVC; //when add that line crashes
SKTransition *reveal = [SKTransition fadeWithDuration:0];
[self.view presentScene:endGameScene transition:reveal];
}
If I don't go to the GameScene there is no problem. The problem is when the user goes to the GameScene and comes back.
I would appreciate any help
Thanks

Presenting a scene in SpriteKit without discarding the previous?

My situation is that I have a GameMenuScene and after the user chooses a level, I want to present the LevelScene. But I do not want to have the previous GameMenuScene discarded because the LevelScene is actually a #property of GameMenuScene and whether or not the user completes the level is to be saved as a #property of LevelScene, which the GameMenuScene should be able to access after the user finishes or exits the level. If I simply use presentScene:transition, the GameMenuScene is discarded and the information cannot pass back.
My question: Is there a way to stack or push the scenes on top of each other without discarding the previous (preferably using a transition animation)? I could not find a method for this specific purpose in the Apple Documentation for SKScene.
Note: Another StackOverflow answer to a similar question suggests to create a new UIViewController, present the LevelScene in there and then present the UIViewController modally. But I was hoping there was an existing method in the Apple Documentation that I have missed to present the scene itself scene modally without having to create UIVIewControllers.
There is no navigation controller-like capability for SKScenes that allows you to push and pop scenes. You will need to write code to manage and present your scenes.
Here's a simple view controller implementation that allows you to switch between two scenes (by swiping) without discarding the other scene.
#interface ViewController()
#property BOOL viewFlag;
#property SKScene *scene1;
#property SKScene *scene2;
#end
#implementation ViewController
- (void)viewDidLoad
{
[super viewDidLoad];
// Configure the view.
SKView * skView = (SKView *)self.view;
skView.showsFPS = YES;
skView.showsNodeCount = YES;
UISwipeGestureRecognizer *swipeGesture = [[UISwipeGestureRecognizer alloc]
initWithTarget:self action:#selector(handleSwipeGesture:)];
swipeGesture.direction = UISwipeGestureRecognizerDirectionRight;
[self.view addGestureRecognizer:swipeGesture];
// Create and configure scene 1.
SKScene * scene = [MyScene sceneWithSize:skView.bounds.size];
scene.scaleMode = SKSceneScaleModeAspectFill;
self.scene1 = scene;
// Present the scene 1.
[skView presentScene:scene];
// Create and configure scene 2.
scene = [MySecondScene sceneWithSize:skView.bounds.size];
scene.scaleMode = SKSceneScaleModeAspectFill;
self.scene2 = scene;
}
- (void) handleSwipeGesture:(id)sender
{
SKView * skView = (SKView *)self.view;
_viewFlag = !_viewFlag;
if (_viewFlag) {
[skView presentScene:_scene1];
}
else {
[skView presentScene:_scene2];
}
}
#end

Transition from ViewController to SKScene

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.
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.

Presenting interstitial ads with SpriteKit restarts entire scene

I am trying to display an admob interstitial ad after receiving a successful ad call :
- (void)interstitialDidReceiveAd:(GADInterstitial *)ad {
DLog(#"interstitialDidReceiveAd");
[ad presentFromRootViewController:self];
}
self is the ViewController instance (which is the root view controller as implemented by the SpriteKit template) and for some reason it displays the ad (which is good) but restarts the entire scene.
I should note that the ad request is done way after the scene is created and being run.
I also noticed this behavior when I tried adding a view to this controller's view property (which is a SpriteKit SKView instance)
And ideas ?
As I thought... I was doing something wrong...
If you stumble upon this problem :
I create my scene in the view controller's method viewWillLayoutSubviews (until this method the view bounds are NOT updated with the desired orientation)
When the interstitial ad is presented this method is called again and of course the scene is recreated as well. So just add a boolean member indicating if the scene was already loaded for creating the scene only once.
Poof, problem is gone:)
There's something funky going on here that's more than just displaying an interstitial. I have a sprite kit project setup where I display the UIImagePickerController from the rootViewController via:
#pragma mark - ImageCatureDelegate methods
-(void)requestImagePicker
{
UIImagePickerController *imagePicker = [UIImagePickerController new];
imagePicker.delegate = self;
[self presentViewController:imagePicker animated:YES completion:nil];
}
#pragma mark - UIImagePickerControllerDelegate
-(void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info
{
UIImage *image = [info objectForKey:#"UIImagePickerControllerOriginalImage"];
[picker dismissViewControllerAnimated:YES completion:^{
SKTexture *imageTexture = [SKTexture textureWithImage:image];
CIFilter *sepia = [CIFilter filterWithName:#"CISepiaTone"];
[sepia setValue:#(0.8) forKey:kCIInputIntensityKey];
imageTexture = [imageTexture textureByApplyingCIFilter:sepia];
SKView *view = (SKView *)self.view;
MyScene *currentScene = (MyScene *)view.scene;
[currentScene setPhotoTexture:imageTexture];
}];
}
during the callback, nothing special is done except dismissing the modal. If admob is pushing a new VC you may see this issue, but if it's displaying a literal modal VC modally... then you shouldn't see this issue. You may want to look into exactly what happens when you push an interstitial ad. If this is the case, and this is the only method you can use, You'll have to NSCode or something to keep the game's state so it can be loaded back up when the interstitial disappears.
Edit:
To append to your solution above, if you use viewWillLayoutSubviews to correct the portrait/landscape issue in SpriteKit, be sure to do it as such so this only happens 'once'
- (void)viewWillLayoutSubviews
{
[super viewWillLayoutSubviews];
// Configure the view.
SKView * skView = (SKView *)self.view;
if (!skView.scene) {
skView.showsFPS = YES;
skView.showsNodeCount = YES;
// Create and configure the scene.
MyScene * scene = [[MyScene alloc] initWithSize:skView.bounds.size andLevelNumber:1];
scene.scaleMode = SKSceneScaleModeAspectFill;
// Present the scene.
[skView presentScene:scene];
}
}

Showing iAds in SpriteKit Game

I get the following error when I try to ad iAds to my SpriteKit game. Anyone know why this is?
-[UIView scene]: unrecognized selector sent to instance 0x10da31fb0
ViewController.m
- (void)viewWillLayoutSubviews
{
[super viewWillLayoutSubviews];
// Configure the view.
SKView * skView = (SKView *)self.view;
if (!skView.scene) {
skView.showsFPS = NO;
skView.showsNodeCount = NO;
// Create and configure the scene.
SKScene * scene = [HomeScreen sceneWithSize:skView.bounds.size];
scene.scaleMode = SKSceneScaleModeAspectFill;
// Present the scene.
[skView presentScene:scene];
self.canDisplayBannerAds = YES;
}
}
In addition to my comment (regarding iAD) the error shows me that somehow to view's class is not correct. It should be SKView.
To correct this go to Interface Builder and for that particular view change the class using the Identity inspector (3rd "tab") to SKView.
It happened to me when manually created from the scratch a SpriteKit project.
Hope it helps! :)
