所以我一直在准备理解崩溃日志，我相信我的崩溃日志符号化了，但我仍然不明白。

根据我的用户告诉我的情况，应用程序在调用“closebidpicker”方法时崩溃。这份崩溃报告到底在这条线上告诉我什么？我假设 750 指的是行偏移，但这种方法不是 750 行长。我彻底糊涂了。

我无法在手机或模拟器中重现此错误。如果我至少能查明它在哪条线上，那就太好了。

编辑：

我正在使用 ccTouchEnded 调用 closebidpicker：

- (void) ccTouchEnded:(UITouch *)touches withEvent:(UIEvent *)event 
{  

    if (bidpicker.startPage==bidpicker.endPage && bidpicker.visible==YES && bidpicker.boo_pickermoved==NO && bidpicker.wasTouching==YES
        && bidpicker.isWindow==YES && bidpicker.wasWindow==YES)
    {
        [self schedule: @selector(closeBidPicker) interval:0.];
    }
}

- (void) closeBidPicker
//(id)sender 
{
    NSLog(@"Entering CloseBidPicker");

    [self reorderChild:_label z:-1];

    int int_currentbid;

    {
        int_player_counter=0;
        [self schedule: @selector(determineBidWinner) interval:1];
    }
}

实际方法确实没有什么特别之处，我看不出它会在 iOS 6 而不是 5 中崩溃的任何原因。

我不明白的是这个...

如果我直接为我的设备构建它，它在我的设备上运行良好，但如果我通过 iTunes 安装 beta 版本，它会崩溃。

我能够找到导致我出现问题的代码。当我注释掉

[self reorderChild:_player1actionlabel z:2];
[self reorderChild:_player1actionlabelbackground z:1];

它工作正常。我完全不知道它为什么这样做。

我不明白为什么/如何，但移动

    [self reorderChild:_player1actionlabel z:1];
    [self reorderChild:_player1actionlabelbackground z:0];

最重要的是我的方法解决了崩溃。
