刷卡删除行不工作

我在我的PFQueryTableViewController（使用Parse.com）实施工作Swipe to Delete。当我去执行取消单元格的行为给我这个错误和应用程序崩溃。刷卡删除行不工作

你能帮我弄清楚我错了吗？

你有这样的代码：

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

    return 0; 
}

这说的是表有0细胞，它的更新后，当表期待4.如果您使用的是静态的细胞在故事板，然后你不应该实现numberOfRowsInSection函数。

如果您删除该代码，那么你应该没有问题。

编辑：或者如果你想要numberOfRowsInSection函数，那么你需要将一个数据源连接到tableview。这将允许您返回数据源的计数。然后，当你删除一行时，你会删除数据源中的相应对象，这样计数就比以前少了1。

您好，感谢您的答复......然后我试图与self.objects.count改变 NSArray的对象是PfqueryTableViewController 但继续crasharee不明白为什么... 附：细胞是动态的，我该怎么办？ – kAiN

您是否尝试通过删除该代码来运行它？它崩溃的原因是因为你的UITableView期望在删除1之后的段中有4行。我的答案中的代码是指定在删除1后，表中应该有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。 –

对不起，如果你不明白，但我没有太多的经验，但我正在学习：D无论如何，我解决了，我仍然与动画工作。我已经完全删除并修改了numberOfRowInSection UITableViewCellEditingStyleDelete，如下所示： [tableView reloadRowsAtIndexPaths：[tableView indexPathsForVisibleRows] withRowAnimation：UITableViewRowAnimationFade]; [tableView endUpdates]; PFObject * object = [self.objects objectAtIndex：indexPath.row]; [object deleteInBackgroundWithBlock：^（BOOL succeeded，NSError * error）{[self loadObjects];}]; 非常感谢Mike +1为你 – kAiN
