我一直在努力弄清楚我的应用程序存在的问题。我已将它提交给苹果，并且已经被拒绝了“2.10详情 我们在运行iOS 9.2.1的iPad上查看时，您的应用程序崩溃了： - 启动时启动“。该应用程序适用于我的iPad第3代，所有模拟器和我的iPhone 6.当我询问它崩溃的设备时，他们说这是iPad Air 2.不幸的是，我不拥有iPad Air 2并没有其他方法可以获得相同的结果。以下是我试图解决问题的方法：
我从.plist中删除了“支持的界面方向（iPad）” - 没有改变
我创建了一个新方案，在模拟器中以发布模式测试应用程序 - 没有错误
我试着象征着崩溃报告，但我还没有从中产生任何东西......我可能做错了。
我已在下面发布了崩溃报告，错误似乎是EXC_BREAKPOINT（SIGTRAP）。据我所知，这是一个与具有零值或失败的力类型转换的非可选类型相关的错误。如果是这种情况，为什么其他设备在启动时不会遇到相同的错误？ iPad Air 2在发布时是否有不同之处，我不知道。我在这一点上的唯一猜测是它与我的构建设置有关。我只包括前几个二进制图像，因为我在这篇文章中没有空格。
