ios - UITableView 无法在 iOS 中显示正确的按钮颜色

Question

我使用了BVReorderTableView https://github.com/bvogelzang/BVReorderTableView重新排序 TableView 中的行。但是我有一个问题:当我将 UIButton 添加到每一行时，这个按钮总是显示清晰的颜色。一旦选择了行，这个按钮就会显示出来。

我试过这段代码:

    - (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{

    static NSString *CellIdentifier = @"Cell";
    UITableViewCell *cell;

    cell = [_tableView dequeueReusableCellWithIdentifier:CellIdentifier];
    UIButton *prioritybtn = [UIButton buttonWithType:UIButtonTypeRoundedRect];

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

        [prioritybtn setFrame:CGRectMake(220, 0, 70, 32)];
        [prioritybtn setTag:4000];
        [cell.contentView addSubview:prioritybtn];

    }
     UIButton *priorityButton = (UIButton*)[cell.contentView viewWithTag:4000];
    if ([[items objectAtIndex:indexPath.row] isKindOfClass:[NSString class]] &&
        [[items objectAtIndex:indexPath.row] isEqualToString:@"DUMMY"]) {
        cell.textLabel.text = @"";
        cell.contentView.backgroundColor = [UIColor clearColor];
        prioritybtn.hidden= YES;
    }
    else {

       cell.textLabel.text = [items objectAtIndex:indexPath.row];
        [priorityButton setSelected:NO];
        [priorityButton setTitle:@"Priority" forState:UIControlStateNormal];
        priorityButton.enabled = YES;
    }

    return cell;
}

此外，我只想隐藏第一行的按钮，其他行仍然显示。我怎样才能做到这一点？谢谢

Answer 1

隐藏第一行的按钮:

    if (indexPath.row == 1){
      prioritybtn.hidden = YES;
      prioritybtn.userInteractionEnabled = NO;
    } else {
      prioritybtn.hidden = NO;
      prioritybtn.userInteractionEnabled = YES;
}

在 return cell; 之前添加这个

关于颜色，在初始化按钮的地方添加:

 UIButton *prioritybtn = [UIButton buttonWithType:UIButtonTypeRoundedRect];
    prioritybtn.backgroundColor = [UIColor greenColor]; //put the color you want
