我有 1在每一行中UITableView有多个 UIButton（命名为“打开”按钮，带有不同的标签），我为它们设置了标签。现在，单击每一行中的任何按钮后，它会显示一个UIView（detailView）。在 detailView 上有 1 个“提交”按钮。我想当用户点击“提交”按钮时，选择标签的“打开”按钮被禁用。我怎样才能做到这一点？我使用了这段代码：

使用多个“打开”按钮创建表格视图的代码：

 - (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
    NSString *CellIdentifier = [NSString stringWithFormat:@"%d,%d",indexPath.section,indexPath.row];

    UITableViewCell *cell = [_tableView dequeueReusableCellWithIdentifier:CellIdentifier];
    if (cell == nil)
    {
        cell = [[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier] autorelease];

        UIButton *market = [UIButton buttonWithType:UIButtonTypeCustom];
        [market addTarget:self action:@selector(marketPressedAction:) forControlEvents:UIControlEventTouchDown];

        [market setTag:3000];
        [market setFrame:CGRectMake(200, 6, 30, 30)];
        [cell.contentView addSubview:market];

    }

    marketButton = (UIButton *)[cell.contentView viewWithTag:3000];
    [marketButton setTag:indexPath.row];


    cell.accessoryType = UITableViewCellAccessoryDetailDisclosureButton;
    _tableView.contentInset = UIEdgeInsetsMake(0, 0, 100, 0);

    return cell;
}

单击“打开”按钮时的代码：

    - (void)marketPressedAction:(id)sender
{

    UIButton *button = (UIButton *)sender;
    buttontag = button.tag;
    NSLog(@"Market button click at row %d",buttontag);

    if ([sender isSelected]) {
        [sender setImage:[UIImage imageNamed:@"Marketplace.png"] forState:UIControlStateHighlighted];
        [sender setSelected:NO];
    }
    else {

            [sender setImage:[UIImage imageNamed:@"MarketplaceSelect.png"] forState:UIControlStateSelected];
            [sender setSelected:YES];
        }
    }
}

EDITED : Change you marketPressedAction parameter id to UIButton * and write code of below

-(void)marketPressedAction:(UIButton *)sender
{

    [sender setImage:[UIImage imageNamed:@"Marketplace.png"] forState:UIControlStateHighlighted];
    [sender setImage:[UIImage imageNamed:@"MarketplaceSelect.png"] forState:UIControlStateSelected];

    /// Here set you image ////////////////
    [sender setImage:[UIImage imageNamed:@"myCustome.png"] forState:UIControlStateNormal];

    [self createMarketPlaceForm]; // call detailView

    sender.enabled = NO;
    sender.userInteractionEnabled = NO;

}

UIButton *btn = (UIButton *)sender;
btn.enabled = NO;

在按钮单击方法中尝试这个

如果您希望在单击提交按钮后禁用“打开”按钮，则应使用委托
