问题

在iOS 8.4,模拟器和手机中,我的performSegue调用没有问题,但是当在Xcode 7 beta 5上使用模拟器时,当进行performSegue调用时,它会崩溃.调用堆栈如下.

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

它看起来与我的代码没有任何关系,因为它发生在过渡期间,我自己的函数都没有在调用堆栈中.

有没有人经历过这个,/或者知道如何解决这个问题?我将断点放在我的第二个视图控制器的每个函数中,没有一个被击中.

  最佳答案

我确信这是错误.在我的情况下,它被指向TabBarView.

  performSegueWithIdentifier("tabSegue",sender: nil)
 

当它开始崩溃时(这发生时间不改变sb)我只是从故事板中删除segue并将其创建回来.它有效.
