完成加载和显示UITableView已正确填充的 a 后,我的应用程序然后崩溃并给出以下输出:

*** Terminating app due to uncaught exception 'NSRangeException', reason: '*** -[__NSArrayM objectAtIndex:]: index 14 beyond bounds [0 .. 13]'

我已经检查了导致 tableview 可能影响它的所有可变数组的内容,它们都返回了预期的数字[mutableArray count];。最奇怪的部分是没有可以填充的单个可变数组,[0 .. 13]因为整个应用程序中没有任何地方具有 14 个索引的数组。

UITableView按预期返回单独的单元格,并且只调用一次cellForRowAtIndexPath(使用检查NSLog)。然后在视图出现后大约半秒到一秒崩溃NSRangeException

该类中唯一的可变数组UITableView已被检查[mutableArray count];并仅返回 1,这是生成的唯一单元格。

当控制台读数没有指示数组是什么或在哪里时,我该如何进行调试,并且突出显示的行只是 main 方法中自动释放的 SIGBART?

它最终成为一个框架版本中的一个相当令人困惑的错误,该框架用于处理前一个视图中数据的类中。
