我的应用程序在iPad发布时崩溃，但在iPhone上正常运行。
我已经尝试将Symbolic breakpoint添加到-[UIView(Hierarchy) setNeedsLayout]，但我找不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：
-[NSConcreteMapTable setNeedsLayout]: unrecognized selector sent to instance 0x17fbdca0
-[_NSConcreteObservation setNeedsLayout]: unrecognized selector sent to instance 0x170235da0
EXC_BAD_ACCESS KERN_INVALID_ADDRESS 0x0000000e9c2cbeb8
还有其他方法可以调试并弄清楚发生了什么吗？
