使用Retina运行动作/仅在iPad Air和iPad mini上加载资源时,Sprite Kit会崩溃

我收到来自视网膜迷你和iPad Air设备的崩溃报告,但不是iPhone 5S.它出现在SpriteKit中,当有人点击一个精灵,然后该精灵应该再次出现在屏幕上.

我无法在非A7设备上重现这一点,所以想知道是否有人可以查看下面的崩溃日志,让我知道崩溃可能是由什么引起的？

这是我用来创建在点击另一个时显示的精灵的代码.除了A7设备之外,其他任何事情都不会发生,而不是在iPhone上.另外,这个相同的代码片段用于在其他sprite上执行完全相同的操作,并且不会在这些sprite上崩溃.

if ([touchedSprite.name isEqualToString:@"Sad"]) {
    // Create the crop node
    if ([[UIDevice currentDevice] userInterfaceIdiom] == UIUserInterfaceIdiomPad) {
        cropNode.position = CGPointMake(touchedSprite.position.x - 120, CGRectGetMinY(self.view.frame));
    } else
        cropNode.position = CGPointMake(touchedSprite.position.x - 120 * IPHONERATIO, CGRectGetMinY(self.view.frame) - 20);


    SKSpriteNode *sadSprite = [SKSpriteNode spriteNodeWithTexture:[SKTexture textureWithImageNamed:@"SadSprite"]];
    [sadSprite setName:@"sadSprite"];
    [cropNode addChild:sadSprite];

    sadSprite.position = CGPointMake(sadSprite.position.x, sadSprite.position.y + sadSprite.size.height / 2);

    SKSpriteNode *maskedImage = [SKSpriteNode spriteNodeWithTexture:[SKTexture textureWithImageNamed:@"SadSpriteMask"]];
    [cropNode setMaskNode:maskedImage];

    [self addChild:cropNode];

    NSArray *slurpSounds = @[@"sadSprite01.caf", @"sadSprite02.caf", @"sadSprite03.caf"];

    // Keep the sadSprite in the same position in relation to the egg
    [sadSprite runAction:[SKAction moveByX:0 y:-sadSprite.size.height duration:0.6]];

    // Move the sadSprite into position
    [cropNode runAction:[SKAction moveByX:0 y:sadSprite.size.height duration:0.6] completion:^{
        [cropNode runAction:[SKAction playSoundFileNamed:slurpSounds[self.toolSoundNumber] waitForCompletion:YES] completion:^{
            [sadSprite runAction:[SKAction moveByX:0 y:sadSprite.size.height duration:0.6] completion:^{
                [sadSprite removeFromParent];
            }];
            [cropNode runAction:[SKAction moveByX:0 y:-sadSprite.size.height duration:0.6] completion:^{
                [cropNode removeFromParent];
            }];
        }];
    }];
}

谢谢.
