Ios _CF_转发_准备_0应用程序运行时崩溃（iPad）

我的应用程序在iPad发布时崩溃，但在iPhone上正常工作。 我已经尝试将

符号断点添加到
-[UIView（Hierarchy）setNeedsLayout]
中，但没有找到导致此问题的原因

在Crashlytics上，我对同一次崩溃有不同的标题，例如：

-[nsconcertematable setNeedsLayout]：发送到实例0x17fbdca0的无法识别的选择器

-[\u NSConcreteObservation setNeedsLayout]：发送到实例0x170235da0的选择器无法识别

EXC\u错误\u访问内核\u无效\u地址0x0000000e9c2cbeb8

有没有其他方法来调试和找出发生了什么
