我对objective-c仍然相当新，我正在寻找一些帮助来解决我的应用程序崩溃。
在我的故事板中，我基本上有一个containerview，它使用embed segue来显示UITableView。基本上一切都运行良好数月，但现在每当访问AddPOIViewController时我都会遇到此崩溃（视图没有出现）。没有警告或错误的构建。任何帮助将不胜感激。

libc ++ abi.dylib：以NSException类型的未捕获异常终止
程序以退出代码结束：0
答案 0 :(得分：0)
尝试设置断点并找到崩溃的确切行？
答案 1 :(得分：0)
听起来segue正在运行多次。你的调用执行segue或其他一些动作试图在它激活时再次调用它。有一个内部断言被击中。
不要那样做;）
