Question

我有一位可贵的书记长,当我试图去除一个囚室和删除新闻时,然后把囚室变成了老板,显示左边的红arrow。但数据已经删除。因为当我重新开会时,情况就已经过去了。我的法典中是否有任何怀疑?

- (BOOL)tableView:(UITableView *)tableView canEditRowAtIndexPath:(NSIndexPath *)indexPath
{
    return YES;
}

- (void)setEditing:(BOOL)editing animated:(BOOL)animate
{
    [self.tableView setEditing: !self.tableView.editing animated:YES];

    if (self.tableView.editing)
        [self.navigationItem.leftBarButtonItem setTitle:@"Done"];
    else
        [self.navigationItem.leftBarButtonItem setTitle:@"Edit"];
}

-(void)tableView:(UITableView *)tableView commitEditingStyle:(UITableViewCellEditingStyle)editingStyle forRowAtIndexPath:(NSIndexPath *)indexPath
 {
     if (editingStyle == UITableViewCellEditingStyleDelete) 
     {
         PFObject *routine= [self.routineArray objectAtIndex:indexPath.row];
         [routine deleteInBackgroundWithBlock:^(BOOL succeeded, NSError *error) {
             if (!error) {
                 [self.tableView reloadData];
             } else {
                 // There was an error saving the gameScore.
             }
         }];   
     }
 }

页: 1 浏览-deleteRowsAtIndexPaths:with Row Animation:,然后从您的核心数据库中删除。该命令很重要,因为如果在你的数据来源中仍然存在,或由于表格而出现一个例外,你可以从表格中删除。从数据来源的物品数量来看。

举例来说,它首先从数据库中删除,然后从数据库中删除,然后从表态中删除,该表也应运作。

-(void)tableView:(UITableView *)tableView commitEditingStyle:(UITableViewCellEditingStyle)editingStyle forRowAtIndexPath:(NSIndexPath *)indexPath
{
    if (editingStyle == UITableViewCellEditingStyleDelete) 
    {
        PFObject *routine= [self.routineArray objectAtIndex:indexPath.row];
        [routine deleteInBackgroundWithBlock:^(BOOL succeeded, NSError *error) {
            if (!error) {
                [self.routineArray removeObjectAtIndex:indexPath.row];
                [self.tableView deleteRowsAtIndexPaths:[NSArray arrayWithObject:indexPath] withRowAnimation:UITableViewRowAnimationFade];
            } else {
                // There was an error saving the gameScore.
            }
        }];   
    }
}
