How to find out where app actually crash? There is a something like "call stack"?
如何找出应用程序实际崩溃的位置？有没有像“调用堆栈”这样的东西？

You have to set Exception BreakpointGo to the Breakpoints navigator, click the + button at the bottom, and add an Exception Breakpoint.
Now you will know the exact line where any of your exception will occur (e.g. line of crash). best of luck!!
您必须设置Exception BreakpointGo to the Breakpoints navigator，单击底部的 + 按钮，然后添加一个 Exception Breakpoint。现在您将知道任何异常将发生的确切行（例如崩溃行）。祝你好运！！

Run your app under the debugger, then when your app crashes you will have access to the call stack.
在调试器下运行您的应用程序，然后当您的应用程序崩溃时，您将可以访问调用堆栈。
Furthermore, if you display the console window, you will get more textual information (including a call stack) at the moment of the crash.
此外，如果您显示控制台窗口，您将在崩溃时获得更多文本信息（包括调用堆栈）。
If you are using Xcode 4, have a look at the attached picture.
如果您使用的是 Xcode 4，请查看所附图片。
