有没有办法看到程序在XCode中崩溃的行数？

我记得使用编译器（我认为JCreator或Eclipse）会告诉你它崩溃的代码行。我无法在XCode中找到此信息。它有这个功能吗？有没有办法看到程序在XCode中崩溃的行数？

编辑：

下面是一个示例堆扔在第一掷

我知道这个崩溃是在我的代码的第112行处引起的（我用nslogs将它包围以缩小它的范围）。但我在这里没有看到112？我只是不想每次都用nslog来跟踪它。

在Xcode中使用“运行和调试”。如果崩溃，调用堆栈位于调试器窗口的左上角。点击顶部的项目查看崩溃的位置。点击其他任何一行即可查看该通话。

虽然我不能点击任何东西，但它只是文本。 – Marty 2011-02-27 02:15:34

我看到它坠毁的方法，只是不是实际的线。 – Marty 2011-02-27 02:26:18

该堆栈说它在系统[UIImageView initWithImage：]中的[LettersFlashCardsViewController viewDidLoad]中崩溃。如果你没有一行说：[[UIImageView alloc] initWithImage：...]，那么你有一个指针问题，因为这是它可以调用的方法。您可以使用viewDidLoad中的断点重新运行程序，并查看mroe细节。 – DavidPhillipOster 2011-02-27 03:07:37

Xcode使用GNU Debugger GDB。在（gdb）提示符下键入'where'或'backtrace'或'bt'，您将看到一个回溯。这会显示导致崩溃的调用堆栈。您将在回溯中看到文件路径和行号。有时这直接指向罪魁祸首。
