无法识别崩溃exceptiontypes：EXC_CRASH（SIGABRT）。 包括崩溃日志
我无法从这个崩溃日志中找出问题。 我已经看到了几个关于EXC_CRASH（SIGABRT）和CFNOTIFICATIONCENTER_IS_CALLING_OUT_TO_AN_OBSERVER的post，但这些都没有帮助。这发生在操作系统版本：iOS 8.3（12F69）和iPad2。

崩溃发生在[NSMutableDictionary setObject:forKey:]并且在该方法中崩溃的一个非常常见的原因是该对象是nil并且在Objective-C集合类中不能保存nil 。 但是应该有一些可以证实这一点的例外文本 。
这就是我现在可以告诉你的一切。
