Using a view controller for a game over scene - ios

Question

I need to make an end screen for my app after the collision detection. What is the easiest possible way to make the end screen with a button back to the main menu/to the game. Can I use a ViewController? I've read a lot of tutorials, videos, and also all of the posts on here:
This is my current code (not all of it just some important things):
#implementation MyScene
static const int squirrelHitCategory = 1;
static const int nutHitCategory = 2;
- (instancetype)initWithSize:(CGSize)size {
if (self = [super initWithSize:size]) {
self.physicsWorld.contactDelegate = self;
_squirrelSprite = [SKSpriteNode spriteNodeWithImageNamed:#"squirrel"];
_squirrelSprite.position = _firstPosition;
_atFirstPosition = YES;
_squirrelSprite.physicsBody = [SKPhysicsBody bodyWithCircleOfRadius:10];
_squirrelSprite.physicsBody.categoryBitMask = squirrelHitCategory;
_squirrelSprite.physicsBody.contactTestBitMask = nutHitCategory;
_squirrelSprite.physicsBody.collisionBitMask = nutHitCategory;
_squirrelSprite.physicsBody.affectedByGravity = NO;
self.physicsWorld.contactDelegate = self;
[self addChild:_squirrelSprite];
SKAction *wait = [SKAction waitForDuration:3.0];
SKSpriteNode *lightnut = [SKSpriteNode spriteNodeWithImageNamed:#"lightnut.png"];
lightnut.physicsBody = [SKPhysicsBody bodyWithRectangleOfSize:CGSizeMake(200,160)];
lightnut.physicsBody.categoryBitMask = nutHitCategory;
lightnut.physicsBody.contactTestBitMask = squirrelHitCategory;
lightnut.physicsBody.collisionBitMask = squirrelHitCategory;
lightnut.physicsBody.affectedByGravity = NO;
self.physicsWorld.contactDelegate = self;
[self addChild: lightnut];
- (void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event {
UITouch *touch = [touches anyObject];
// Check time since the last touch event
if (touch.timestamp-_lastTouch >= .9) {
// Allow touch
NSLog(#"greater than or equal to 3 seconds");
if (_atFirstPosition)
{
SKAction *moveNodeLeft = [SKAction moveByX:-207.8 y:0.0 duration:0.85];
[_squirrelSprite runAction: moveNodeLeft withKey:#"moveleft"];
} else {
SKAction *moveNodeRight = [SKAction moveByX:207.8 y:0.0 duration:0.85];
[_squirrelSprite runAction: moveNodeRight withKey:#"moveright"];
}
_atFirstPosition = !_atFirstPosition;
_squirrelSprite.xScale *= -1.0;
}
else {
// Ignore touch
NSLog(#"Seconds since last touch %g",touch.timestamp-_lastTouch);
}
// Store timestamp
_lastTouch = touch.timestamp;
}
-(void)didBeginContact:(SKPhysicsContact *)contact
{
NSLog(#"contact detected");
SKPhysicsBody *firstBody, *secondBody;
firstBody = contact.bodyA;
secondBody = contact.bodyB;
if(firstBody.categoryBitMask == squirrelHitCategory || secondBody.categoryBitMask == nutHitCategory)
{
}
}
I want my end screen to be simple, so the easiest way to make it is best. Thank you!

For my games I add a UIViewController property and assign it to the SKScene.
You can then add a view as a sub view. Example...
SKScene *scene = [SKScene sceneWithSize:self.view.frame.size];
scene.viewController = self;
Then in your scene...
[self.viewController addSubview:yourView];
Here is some of my own game's implementation to help get you started.
In your Storyboard, or XIB whichever you prefer you add a view with buttons as properties of the view. In my case I have a scoreLabel, a menuButton, and a restartButton as properties and can set them all as x.hidden = YES; as I wish by triggering them in the scene such as...
self.vc.menuButton.hidden = YES;
self.vc.restartButton.hidden = YES;
In your GameViewController (Which is a subclass of UIViewController)...
//header
#interface GameViewController : UIViewController
#property (weak, nonatomic) IBOutlet UILabel *scoreLabel;
#property (weak, nonatomic) IBOutlet UIView *hudView;
#property (weak, nonatomic) IBOutlet UIButton *menuButton;
#property (weak, nonatomic) IBOutlet UIButton *restartButton;
#property (nonatomic) MazeScene *maze;
#end
//class
- (void)viewDidLoad
{
[super viewDidLoad];
// Configure the view.
SKView * skView = (SKView *)self.view;
// Debug Options
// skView.showsFPS = YES;
// skView.showsNodeCount = YES;
// skView.showsPhysics = YES;
// Create and configure the maze scene.
CGSize sceneSize = skView.bounds.size;
skView.ignoresSiblingOrder = YES;
MazeScene *maze = [[MazeScene alloc] initWithSize:sceneSize];
maze.scaleMode = SKSceneScaleModeAspectFill;
maze.vc = self;
[skView presentScene:maze];
_maze = maze;
}
In your SKScene...
//header
#interface MazeScene : SKScene <SKPhysicsContactDelegate>
#property (nonatomic, weak) GameViewController *vc;
#end
//class
-(id) initWithSize:(CGSize)size {
if (self = [super initWithSize:size]) {
//(GameViewController*) is a static cast of a subclass of UIViewController.
[self.view addSubview:((GameViewController*)self.vc).hudView];
// [self restartGame] is a specific method for my game, don't worry about it
[self restartGame];
}
return self;
}
