Ios8 iOS 8 SpriteKit渲染问题

在iOS 8中测试我的应用程序时，我遇到了一些严重的渲染问题。与其浪费文字试图写一个可理解的描述，我只给你看一个简短的视频：

这就是它的工作原理

就是这样

您所看到的内容的一个小分解：放大的瓷砖是一个单独在每个瓷砖上运行的SKAction。瓷砖以0的alpha值生成，SKAction将逐渐淡入，一次一个。如果我生成alpha值为1.0的瓷砖，它们会出现，但不会执行任何操作。其他操作也不会随机运行。因此，至少在行动上似乎存在一些问题。不过，当新的一轮发生时，我不知道是什么让场景的其余部分消失了。根本没有与这些节点或纹理相关的操作

有人知道iOS 8中SpriteKit是否有新的限制或问题吗？特别是与SKAction有关，但有什么可能与此相关的吗

编辑：我只是想澄清一下，尽管iOS 8的视频是模拟器，但我已经收到了一份来自beta测试人员的报告，在一台真正的iOS 8设备上出现了与此完全相同的问题。iOS 7视频是我自己的iOS 7设备的屏幕截图

编辑：以下是一些与此相关的代码：

更新方法以确保游戏未暂停。

有机会看到任何代码吗？至少行动本身是好的。我会尽我所能发布。这是相当困难的，因为有几个类都是相互关联的。在设备或模拟器上进行u r测试在文章中对此进行了解释。

self.paused = NO;
