Question

我正在开发一个已经存在的应用。这个应用程序在iPad Pro / iOS 10上工作正常。我试图让它在iPad2 / iOS 9.3.5上运行。

我设法用XCODE构建它。我可以玩得很好。但是，当我加载特定场景时，它会崩溃。 XCODE只显示“iPad已断开连接”。最后一个Debug显示：

“卸载3个未使用的序列化文件（现在加载的序列化文件：0）”

没有警告，没有错误。

经过多次研究，我认为这是一个内存限制问题。所以我开始逐一清空场景，以找出造成问题的原因。

场景现在是空的（^^），它仍然崩溃。下面是空场景的分析器内存。

崩溃日志：

感谢您阅读我， q

谢谢Guru你的时间，

确实，与记忆有关。我正在加载很多GameObjects。很多这些游戏对象都处于非活动状态，所以我认为它们并没有占用大量内存。我错了。我现在使用Instantiate，Destroy方法而不是SetActive（）方法。
