找出nsrangeexception的来源 [英] Finding out source of nsrangeexception

问题描述

我有一个不会一直发生的 NSRangeException 错误（特别是在调试时）。它随机出现，我无法弄清楚它是从哪里来的。我有很多的数组操作，所以它很难消除这样的方式。我的问题是我是否可以得到一个线索，例如调试器输出中的类和行号，例如数字12109和707？：

  2012-03-15 09：25：15.303 appname [12109：707] ***由于未捕获的异常'NSRangeException'终止应用程序，原因：'***  -  [__ NSArrayI objectAtIndex：]：index 2 beyond bounds [0 .. 0]'
  

任何指针都赞赏。

终止称为抛出异常
  

解决方案

添加一个异常断点。这将阻止引发异常的行。

在断点导航器中，单击左下角的加号，选择异常断点和所有异常。你应该在所有项目上真正实现这一点，这是非常宝贵的。尽管如此，我们的问题要少得多

I have an NSRangeException error that does not occur all the time(especially when I am debugging). It comes up randomly, and I am unable to figure out where it is coming from. I have lots of array manipulation, so its difficult to eliminate it that way.

My question is whether I can get a clue , for example class and line number from the debugger output, for example what are the numbers 12109 and 707?:

2012-03-15 09:25:15.303 appname[12109:707] *** Terminating app due to uncaught exception 'NSRangeException', reason: '*** -[__NSArrayI objectAtIndex:]: index 2 beyond bounds [0 .. 0]'

Any pointers appreciated.

Edit: Remaining part of the log:

terminate called throwing an exception

解决方案

Add an Exception breakpoint. This will stop on the line that raises the exception.

In the breakpoints navigator, click the plus in the bottom left, choose exception breakpoint, and all exceptions. You should have this on all projects really, it is invaluable. We'd have far fewer questions here, though!
