ios - 将SKTexture加载到设备时出错

我已经创建了在模拟器上可以正常工作的动画，但是当我使用设备时，屏幕上会出现一个大十字。我收到以下日志消息。

SKTexture: Error loading image resource: "Bird1"

我已经仔细检查了所有纹理都在捆绑资源中。它怎么会不显示在设备上？

    SKTexture* birdTexture1 = [SKTexture textureWithImageNamed:@"Bird1"];
    birdTexture1.filteringMode = SKTextureFilteringNearest;

    SKTexture* birdTexture2 = [SKTexture textureWithImageNamed:@"Bird2"];
    birdTexture2.filteringMode = SKTextureFilteringNearest;
    SKTexture* birdTexture3 = [SKTexture textureWithImageNamed:@"Bird3"];
    birdTexture3.filteringMode = SKTextureFilteringNearest;
    SKTexture* birdTexture4 = [SKTexture textureWithImageNamed:@"Bird4"];
    birdTexture4.filteringMode = SKTextureFilteringNearest;
    SKTexture* birdTexture5 = [SKTexture textureWithImageNamed:@"Bird5"];
    birdTexture5.filteringMode = SKTextureFilteringNearest;
    SKTexture* birdTexture6 = [SKTexture textureWithImageNamed:@"Bird6"];
    birdTexture6.filteringMode = SKTextureFilteringNearest;
    SKAction *flap = [SKAction repeatActionForever:[SKAction animateWithTextures:@[birdTexture1, birdTexture2, birdTexture3, birdTexture4, birdTexture5, birdTexture6] timePerFrame:0.15]];

    SKSpriteNode *mover = [SKSpriteNode spriteNodeWithTexture:birdTexture1];
    [mover setScale:1.0];
    mover.position = CGPointMake(self.frame.size.width / 2, self.size.height-120);

    [mover runAction:flap withKey:@"birdGo"];

    [self addChild:mover];

最佳答案

您是否尝试过如下扩展名的图像文件名？

SKTexture* birdTexture1 = [SKTexture textureWithImageNamed:@"Bird1.png"];

否则请尝试其他方法，如下所示

SKTexture * texture = [SKTexture textureWithImage:[UIImage imageNamed:@"rocket.png"]];
