ios - UITableView - 更改与按下的按钮位于同一行的文本字段

Question

我是第一次尝试使用表格 View ，对于在对单元格执行操作(例如按下按钮)时如何区分文本字段等 UI 元素感到困惑。

现在我在每一行上都有一个按钮和一个文本字段。为此:

- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
static NSString *CellIdentifier = @"gameCell";
    gameViewCell *cell = [tableView
                        dequeueReusableCellWithIdentifier:CellIdentifier
                        forIndexPath:indexPath];

    long row = [indexPath row];

//Button to change text field
    strokeUp = [UIButton buttonWithType:UIButtonTypeCustom];
    strokeUp.frame = CGRectMake(248.0f, 11.0f, 80.0f, 32.0f);
    [strokeUp setTag:indexPath.row];
    [strokeUp addTarget:self action:@selector(addStroke:) forControlEvents:UIControlEventTouchUpInside];
    [cell.contentView addSubview:strokeUp];

//Text field that changes (puts '1' in box for now)
    strokesBox = [[UITextField alloc] initWithFrame:CGRectMake(223.0f, 11.0f, 37.0f, 32.0f)];
    strokesBox.delegate = self;
    [strokesBox setTag:indexPath.row];
    [cell.contentView addSubview:strokesBox];

    return cell;
}

这就是我在点击 strokeUp 按钮时正在做的事情。我希望与按钮位于同一行的文本字段显示“1”(稍后它会将 1 添加到框中当前的内容)。行数从 2 到 6 不等，具体取决于用户在上一屏幕中选择的行数。

- (void)addStroke:(id)sender
{
    CGPoint buttonPosition = [sender convertPoint:CGPointZero toView:table];
    NSIndexPath *indexPath = [table indexPathForRowAtPoint:buttonPosition];
    UIButton *senderButton = (UIButton *)sender;
    if (senderButton.tag == 0)
    {
        NSLog(@"Row 1");
        UITableViewCell *cell = [table cellForRowAtIndexPath:indexPath];
        UITextField *sampleField = (UITextField *)[cell viewWithTag:0];
        theTextField = @"1";
    }
    else if (senderButton.tag == 1) {
        NSLog(@"Row 2");
        UITableViewCell *cell = [table cellForRowAtIndexPath:indexPath];
        UITextField *sampleField = (UITextField *)[cell viewWithTag:1];
        sampleField.text = @"1";
    }
}

Answer 1

设置textfield标签和button say不同

    [strokesBox setTag:indexPath.row+10];


// and set this code in action


- (void)addStroke:(id)sender
{
    int tag = [(UIButton *)sender tag] 
    UITextField *textField = (UITextField *)[table viewWithTag:tag+10];
    textField.text=[NSString stringWithFormat:@"%d",tag+1];
}
