ios - Sprite Kit，灰色背景而不是图像

Question

我似乎无法让我的背景显示图像。

代码如下:

@implementation GameScene

 - (id)initWithSize:(CGSize)size {
    if ((self = [super initWithSize:size])) {

        self.anchorPoint = CGPointMake(0.5, 0.5);

        SKSpriteNode *background = [SKSpriteNode spriteNodeWithImageNamed:@"Background"];
        [self addChild:background];
    }
    return self;
}

@end

 - (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 = SKSceneScaleModeResizeFill;

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

Answer 1

我认为问题在于当您 unarchiveFromFile: 而不是尝试在您的场景中使用 didMoveToView: 时，initWithSize: 实际上并未被调用。

-(void)didMoveToView:(SKView *)view {
    /* Setup your scene here */
    SKSpriteNode *background = [SKSpriteNode spriteNodeWithImageNamed:@"Background"];
    [self addChild:background];
}

希望对您有所帮助。
