调整SpriteKit场景的大小

我试图根据用户使用的设备使场景变得不同,并且除了应用程序加载时,此方法一直很有效。例如,应用程序加载并且屏幕大小不正确,但是当我转到新场景时,大小将达到它的预期。即使你回到起始场景,它也会是正确的尺寸。它仅在应用程序首次加载时关闭,直到您转到新场景。这是代码,任何帮助将不胜感激。

- (void)viewDidLoad
{
[super viewDidLoad];

iphone4x = 1.2;
iphone4y = 1.4;
iphone5x = 1.1;
iphone5y = 1.18;


// Configure the view.
SKView * skView = (SKView *)self.view;
skView.showsFPS = NO;
skView.showsNodeCount = NO;
/* Sprite Kit applies additional optimizations to improve rendering performance */
skView.ignoresSiblingOrder = YES;

CGSize newSize;

if(iPhone4) {

    newSize = CGSizeMake(skView.bounds.size.width * iphone4x, skView.bounds.size.height * iphone4y);


}


if (iPhone5) {


    newSize = CGSizeMake(skView.bounds.size.width * iphone5x, skView.bounds.size.height * iphone5y);


}


if (iPhone6) {


    newSize = CGSizeMake(skView.bounds.size.width, skView.bounds.size.height);


}

if(iPhone6Plus) {





}





// Create and configure the scene.
SKScene *scene = [MainMenu sceneWithSize:newSize];
scene.scaleMode = SKSceneScaleModeAspectFill;

// Present the scene.
[skView presentScene:scene];
}

默认情况下,视图以纵向方式加载,因此即使应用程序应以横向方式运行,也可能会使用纵向模式的坐标。这是一种已知的行为。因此,如果您在横向模式下运行应用程序,那么这可能是个问题。

在调用viewWillLayoutSubviews方法时,视图的大小将是正确的。

尝试使用viewWillLayoutSubviews而不是viewDidLoad:

 - (void)viewWillLayoutSubviews
    {

        [super viewWillLayoutSubviews];


        // Configure the view.
        SKView * skView = (SKView *)self.view;
        skView.showsFPS = YES;
        skView.showsNodeCount = YES;
        skView.showsDrawCount = YES;
        //skView.showsQuadCount = YES;

        skView.showsPhysics = YES;
        skView.ignoresSiblingOrder = YES;

//you have to check if scene is initialised because viewWillLayoutSubviews can be called more than once
        if(!skView.scene){
            // Create and configure the scene.

            //instead of this from your code
           //SKScene *scene = [MainMenu sceneWithSize:newSize];

            //use this line
            MainMenu * scene = [MainMenu sceneWithSize:newSize];

            scene.scaleMode = SKSceneScaleModeAspectFill;

            // Present the scene.
            [skView presentScene:scene];
        }


}
