ios - SKLabelNode 未显示在屏幕上

Question

在私有(private)接口(interface)中

   @property BOOL contentCreated

然后在执行

//just like in Apple's example project

- (void)didMoveToView: (SKView *) view {
   if (!self.contentCreated) {
       [self createSceneContents];
       self.contentCreated = YES;
   }
}

- (void)createSceneContents {
    self.backgroundColor = [SKColor whiteColor];
    self.scaleMode = SKSceneScaleModeAspectFill;
    SKLabelNode *newGameNode = [[SKLabelNode alloc] initWithFontNamed:
        @"Helvetica"];
    newGameNode.name = @"NewGame";
    newGameNode.text = @"New Game";
    newGameNode.fontSize = 30;
    newGameNode.fontColor = [SKColor whiteColor];
    newGameNode.position = CGPointMake(100, 100);
    [self addChild:newGameNode];
}

但是当我运行时，屏幕上什么也没有显示。我做错了什么？

Answer 1

这是因为您在白色背景上显示白色文本。试试这个:

newGameNode.fontColor = [SKColor blackColor];
