我正在我的PFQueryTableViewController（使用Parse.com）中实现滑动到删除的工作。当我去执行取消单元格的操作时，给我这个错误，应用程序崩溃。

你能帮我弄清楚我错在哪里吗？

答案 0 :(得分：1)
您有以下代码：
-(NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section {
return 0;
}
当表格预期为4时，告诉表格在其中有0个单元格。如果在故事板中使用静态单元格，那么就不应该实现numberOfRowsInSection函数。
如果删除该代码，则应该没有问题。
编辑： 或者，如果您确实需要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，您将删除数据源中的相应对象，以使计数比以前少1。
