我以前见过这个，肯定是你忘记了更新填满表的数据源。但是那部分代码缺失。造成这种情况的方法是

 

- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section { 
    return ; 
}

漂亮从错误信息明确：

“无效更新：在部分0包含在现有部分中的行数无效号码的行在之后，更新（6）必须等于更新前（012），减去插入的行数或删除该部分中的部分中包含的行数（0插入， 1删除）。'

您尝试删除的对象不会在数据源中被删除。
如果我假设您的UITableViewDataSource也使用dbManager，则必须修复dbManager以实际删除该对象。

是的，问题是方法numberOfRowsInSection 所以，留下后患，你应该：

在功能上与阵列，数据库等
递减当前的行数commitEditingStyle删除数据。
[tableView beginUpdates];
[self.tableView deleteRowsAtIndexPaths:[NSArray arrayWithObject: indexPath] withRowAnimation:UITableViewRowAnimationFade];
[tableView endUpdates];

而且都是OK！

你需要包裹[开始和结束]内更新？ – alexzg 2014-05-06 02:09:44

我得到了同样的错误，原因是我删除最后一行中的表和为0 我numberOfSectionsInTableView实现收益rowsArray计..

变为最小值1破案

最新Swift解决方案

如果您要删除节中的最后一行，您应该删除整个节而不是行。要做到这一点：

tableView.beginUpdates() 
    self.dataArray.removeAtIndex(index.row) 
    if tableView.numberOfRowsInSection(index.section) == 1 { 
    tableView.deleteSections(NSIndexSet(index: index.section), withRowAnimation: .Automatic) 
    } 
    else { 
    tableView.deleteRowsAtIndexPaths([index], withRowAnimation: .Fade) 
    } 
    tableView.endUpdates()
