SpriteKit崩溃与std :: out_of_range：vector问题
所以我正在试图确定这次事故的原因是什么。 请看这里的崩溃报告： 
这是在日志中产生的：libc ++ abi.dylib：以std :: out_of_range：vectortypes的未捕获exception
基本上，崩溃不会一直发生，似乎在更新的iOS设备上发生。 如果我清理我的构build，我已经注意到它发生的可能性要小得多。 我假设它可能与我的纹理地图集有关系？
有没有人有这个相同的问题，你做了什么来解决？ 需要指出正确的方向在这里做了一段时间的尝试和错误，而不是所有的纹理负载，但一直没能find它。
提前致谢！

解决：由于一些成员的帮助，如何debugging这个错误是什么导致了这个问题。 事实certificate，在preload方法之后， circle_explode_textures被分配了，这就解释了为什么有时候它有效，有时不行。 简单的解决方法就是在调用预加载之前移动纹理数组的alloc，以确保它们在预加载完成时可用。
我看到这个错误发生在你试图运行一个+ (SKAction *)animateWithTextures:(NSArray *)textures动作使用一个数组是无或包含SKTexture以外的SKTexture 。 在传递给animation操作的纹理数组上设置日志，看看是否所有项目都被正确添加。 或者也许有些纹理数组在被执行animation之后被初始化/填充。
