SpriteKit崩溃与std :: out_of_range：矢量问题

Question

所以我试图确定这崩溃的原因究竟是什么。请在这里看到的崩溃报告：

这就是在日志中产生： 的libC++ abi.dylib：矢量

基本上崩溃不会：与类型为std未捕获的异常:: out_of_range终止一直发生，似乎发生在更新的iOS设备上。如果我清理我的版本，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？

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试验和错误，而不是所有的纹理负载，但一直没能找到它。

在此先感谢！

现在这就是我因此载入我的所有纹理。 present_game_view会调用这个启动方法，在这里这些是什么导致崩溃，加载这些纹理。

[camera addChild:logo]; 

解决方法： 由于从成员一些帮助就如何调试这里这个错误是什么造成了这个问题。 事实证明circle_explode_textures在预加载方法之后被分配，因此这解释了为什么它有时可以工作，有时不能。简单的修复就是在调用预加载之前移动纹理数组的alloc，以确保预加载完成时它们可用。

我看到这个错误发生在当您试图运行+ (SKAction *)animateWithTextures:(NSArray *)textures操作使用数组为零或包含SKTexture以外的对象。在您传递给动画操作的纹理数组上设置日志，以查看是否所有项目都正确添加。或者，也可以在之后初始化/填充一些纹理阵列执行动画操作。
