由于我的应用程序今天刚刚上线,所以这很紧急。
我的应用程序在模拟器中运行良好,当我将其复制到手机、iPad和其他iPhone时运行良好。我们测试了这个应用程序。我将它提交到了应用商店,现在它已被批准并处于活动状态,但只有下载的应用商店应用程序才会出现错误。
基本上,我正在使用NSDecimal和数字格式化程序重新平衡账单。在模拟器和手机中,当我逐步完成代码时,一切都很好。但应用商店的捆绑包已经过时了。似乎我正在添加和减去的数据没有初始化。
有人见过这样的东西吗?
我知道这篇文章非常模糊,但我想弄清楚如果模拟器中的代码运行良好,从哪里开始调试。
--UPDATE—添加代码

我认为问题在于您试图使用UITableViewCells进行数据存储。您不将数据推入单元格,而是等待UITableView调用您的cellForRowAtIndexPath方法。
UITableView将只保留足够的单元格来填充屏幕。一旦一个滚动离开视线,它就会被释放。当您的循环尝试使用cellForRowAtIndexPath:再次检索它时,它将分配一个新的单元格给您。虽然您的循环可能会初始化它,但它不会被UITable对象存储或使用。
我的方法中有两个变量存在死存储问题。尽管我后来设置了它们,但我还是删除了它们并重新提交了应用程序。这个问题消失了。
谢谢你的建议。
