Uitableview 滑动以删除不工作的行

我正在PFQueryTableViewController（使用Parse.com）中实现works滑动删除。当我去执行取消行动的细胞给我这个错误和应用程序崩溃

您有以下代码：

-(NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section {

    return 0;
}

这表示在更新后，当表预期为4时，通知表中包含0个单元格。如果在故事板中使用静态单元格，则不应实现numberOfRowsInSection函数

如果您删除了该代码，那么您应该没有问题

编辑：

或者，如果确实需要numberOfRowsInSection函数，则需要将数据源连接到tableview。这将允许您返回数据源的计数。然后，当您删除一行时，您将删除数据源中相应的对象，使计数比以前少1。

您好，谢谢您的回复。。。然后，我尝试使用self.objects.count更改PfqueryTableViewController中的NSArray对象，但仍无法理解为什么。。。P.S.单元格是动态的，我该怎么办？您是否尝试在删除代码的情况下运行它？它崩溃的原因是UITableView希望在删除1后节中有4行。我的回答中的代码指定删除1后，表的节中应该有0行。因此，发生异常是因为0！=4.或者

self.objects.count的结果不等于4。尝试删除numberOfRowsInSection函数。如果您不理解，我很抱歉，但我没有太多经验，但我正在学习：D无论如何，我解决了，我仍在处理动画。我已完全删除并修改了numberOfRowInSection UITableViewCellEditingStyleDelete，如下所示：[tableView重新加载RowSatindExpaths:[tableView InExpathsForVisibleRows]和RowAnimation:UITableViewRowAnimationFade]；[tableView EndUpdate]；PFObject*object=[self.objects objectAtIndex:indexath.row]；[object DeleteInBackgroundithBlock:^（布尔成功，N错误*错误）{[self-loadObjects]；}]；非常感谢Mike+1为您服务Hanks Rory，您可以在PFQueryTableViewController示例代码中找到解决此奇怪问题的正确方法。也许你应该把它贴出来作为一个答案，让别人看得更清楚？
