本文介绍了当我在表视图上选择一个单元格时，我的应用程序崩溃，但我无法找到代码中崩溃的位置的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！

问题描述

我正在尝试从表格视图切换到详细视图。当我点击单元格时它会崩溃。我已经使用了休息来尝试找到它崩溃的代码，但我找不到特定的行。当从表视图到详细视图执行segue时，它会崩溃。我想将一些变量传递给详细视图但我首先需要让它切换到详细视图。我正在使用故事板fyi。任何帮助将不胜感激。

I am trying to switch from a table view to a detail view. When I click on the cell it crashes. I have used breaks to try and find where in the code it crashes but I cant find a specific line. It crashes when the segue is performed from the table view to the detail view. I would like to pass some variables to the detail view but I first need to get it to switch to the detail view. I am using storyboard fyi. Any help would be appreciated.

更新：崩溃日志如下

arg c = (int) 1
arg v = (char **) 0x2fd63cdc

这是崩溃所在的行

return UIApplicationMain(argc, argv, nil, NSStringFromClass([AppDelegate class]));

更新2

最后一节当我逐步执行代码时崩溃之前的代码就是为segue函数做准备。在那里的最后一行代码之后它崩溃并转到上面一行。

The last section of code before it crashes when I am stepping through the code is the prepare for segue function. After the last line of code in there it crashes and goes to the line above.

更新3

我意识到控制台已被隐藏，因此这是控制台中显示的错误。我的两个准备segue的nslog都被调用了。

I realized the console was hidden so this is the error that shows up in the console. Both of my nslogs in prepare for segue were called.
