Question

我的代码是：

- (void)  tableView:(UITableView *)tableView
 commitEditingStyle:(UITableViewCellEditingStyle)editingStyle
  forRowAtIndexPath:(NSIndexPath *)indexPath{
    if (editingStyle == UITableViewCellEditingStyleDelete){
        /* First remove this object from the source */
        [self.allRows removeObjectAtIndex:indexPath.row];

        /* Then remove the associated cell from the Table View */
       [tableView deleteRowsAtIndexPaths:@[indexPath]
                        withRowAnimation:UITableViewRowAnimationFade];

        }
}

我收到如下错误

Answer 1

我认为您的TableView可能会在您创建后发布，并且方法结束。您可能需要在View控制器中创建一个引用它的实例变量。

@property (strong, nonatomic) IBOutlet UITableView *tablview;

然后从表视图中删除关联的单元格

[self.tablview  deleteRowsAtIndexPaths:@[indexPath]
                        withRowAnimation:UITableViewRowAnimationFade];

可以帮助你..

试试这个

-(void)tableView:(UITableView *)tableView commitEditingStyle:(UITableViewCellEditingStyle)editingStyle forRowAtIndexPath:(NSIndexPath *)indexPath

{
    //remove the row from data model
    [tableData removeObjectAtIndex:indexPath.row];
    [tableView deleteRowsAtIndexPaths:@[indexPath] withRowAnimation:UITableViewRowAnimationAutomatic];
}
