我下载了Mapbox提供的Mapbox.unity软件包，并将其导入到我的空Unity项目中。然后，我为Ios进行了构建。有一个渲染的地图，我可以环顾四周。我可以关闭UI叠加层，但是只要我在屏幕上的其他位置滑动，它就会崩溃。
使用： Unity 2019.1.8f1 xCode 10.2.1 具有iOS 12.3.1的iPhone 7
输出中没有直接的错误消息，这让我更加困惑。如果我在连接调试器的情况下运行该应用程序，则该应用程序将停在出现以下错误的行：
Thread 1: EXC_BAD_ACCESS (code=1, address=0x0)
它停在的行看起来像这样： Marshal_Copy_m ...（（intptr_t）L_2，L_3、0，L_4，/ 隐藏参数 / NULL）;
它在程序集csharp14脚本中。我不认为该错误是由该脚本引起的，但我只是无法确定它的来源。
以下是一些发生的输出：

我已经看到了nullpointerexeption，但这似乎不是问题。我调试了特定函数中的所有值，似乎camera.nearClipingPlane尚未准备就绪，并在第一帧中引发该错误。在随后的每个帧中都没有错误。
所以我不知道是什么原因导致崩溃的。
