SpriteKit崩潰與std :: out_of_range：矢量問題

Question

所以我試圖確定這崩潰的原因究竟是什麼。請在這裏看到的崩潰報告：

這就是在日誌中產生： 的libC++ abi.dylib：矢量

基本上崩潰不會：與類型爲std未捕獲的異常:: out_of_range終止一直髮生，似乎發生在更新的iOS設備上。如果我清理我的版本，我已經注意到它發生的可能性要小得多。我假設它可能與我的紋理地圖集有關？

有沒有人有這個相同的問題，你做了什麼來解決？需要指出正確的方向在這裏做了一段時間的試驗和錯誤，而不是所有的紋理負載，但一直沒能找到它。

在此先感謝！

現在這就是我因此載入我的所有紋理。 present_game_view會調用這個啓動方法，在這裏這些是什麼導致崩潰，加載這些紋理。

解決方法： 由於從成員一些幫助就如何調試這裏這個錯誤是什麼造成了這個問題。 事實證明circle_explode_textures在預加載方法之後被分配，因此這解釋了爲什麼它有時可以工作，有時不能。簡單的修復就是在調用預加載之前移動紋理數組的alloc，以確保預加載完成時它們可用。

我看到這個錯誤發生在當您試圖運行+ (SKAction *)animateWithTextures:(NSArray *)textures操作使用數組爲零或包含SKTexture以外的對象。在您傳遞給動畫操作的紋理數組上設置日誌，以查看是否所有項目都正確添加。或者，也可以在之後初始化/填充一些紋理陣列執行動畫操作。
