需要帮助来解读QuincyKit的崩溃日志

我最近在应用程序中添加了QuincyKit（位于PLCrashReporter之上的崩溃日志记者），并收到了我无法解释的崩溃日志。需要帮助来解读QuincyKit的崩溃日志

崩溃日志似乎不一致 - 它表示它是线程0崩溃，但“最后一个异常回溯”与线程0 callstack不匹配。最后一个异常指向一个表方法，但是线程0 callstack表示在Quincy管理器初始化期间发生中止。

此外，“Last Exception Backtrace”似乎没有多大意义 - “canEditRowAtIndexPath”方法甚至不包含对“removeObjectAtIndex”的调用（参见下面的方法）。

任何人都可以阐明我是否应该关注“Last Exception Backtrace”还是一个红色的鲱鱼，我真的应该看看为什么PLCrashReporter在启动过程中放弃了？

非常感谢

“canEditRowAtIndexPath” 的方法：

-(BOOL) tableView:(UITableView *)tableView canEditRowAtIndexPath:(NSIndexPath *)indexPath 
{ 
    if (tableView.tag == SIGNER_TABLE_TAG_VALUE) 
    { 

     RouteStopData *currentStop = [CurrentRoute singleton].selectedStop; 
     NSArray *signers = [currentStop signerNamesForStop]; 

     if (indexPath.row >= [signers count]) 
     { 
      return NO; 
     } 

     if ([[signers objectAtIndex:indexPath.row] isEqualToString:DARK_DROP_SIGNER_STRING] || 
      [[signers objectAtIndex:indexPath.row] isEqualToString:PAPER_INVOICE_SIGNER_STRING] || 
      [[signers objectAtIndex:indexPath.row] isEqualToString:ADD_NEW_SIGNER_STRING] 
      ) 
     { 
      return NO; 
     } 

     return YES; 
    } 

    return NO; 
}

如果使用ios7，这也许UIKit中的故障。
Tableview想在dealloc之前调用委托方法。
所以，你可以在你的自定义类添加以下代码：

- (void)dealloc{ 
    self.tableView.dataSource = nil; 
    self.tableView.delegate = nil; 
}
