iOS 9推送segue导致我的应用程序崩溃

Question

在iOS 8.4,模拟器和手机中,我的performSegue调用没有遇到任何问题,但是当在Xcode 7 beta 5上使用模拟器时,当执行performSegue调用时,它会崩溃.调用堆栈如下.

*** Terminating app due to uncaught exception 'NSRangeException', reason: '*** -[__NSArrayM insertObject:atIndex:]: index 3 beyond bounds [0 .. 1]'

libc++abi.dylib: terminating with uncaught exception of type NSException

看起来它与我的代码有什么关系,因为它在转换期间发生,并且我自己的函数都没有在调用堆栈中.

有没有人经历过这个,和/或知道如何解决这个问题？我在第二个视图控制器的每个函数中都放置了断点,但没有一个被击中.

Answer 1

有些人报告说，将 Segue 指向 ViewController 而不是 NavigationController 可以解决此问题。如果适合的话，您可以尝试该选项。
