ios - UIView 是 tableView 中的隐藏部分标题

Question

我想在 tableView 部分标题上显示一个按钮:我正在使用 UIView 托管按钮，但它与部分标题重叠。这是 viewForHeaderInSection 方法:

- (UIView *)tableView:(UITableView *)tableView viewForHeaderInSection:(NSInteger)section
{

    static NSString *header = @"customHeader";

    UITableViewHeaderFooterView *vHeader;

    id <NSFetchedResultsSectionInfo> theSection = [[self.fetchedResultsController sections] objectAtIndex:section];

    NSString *tmp = [theSection name];
    NSLog(@"SECTIONNAME = %@",tmp);

    vHeader = [tableView dequeueReusableHeaderFooterViewWithIdentifier:header];
    NSLog(@"SECTION = %ld",(long)section);

    if (!vHeader) {
        vHeader = [[UITableViewHeaderFooterView alloc] initWithReuseIdentifier:header];
        vHeader.textLabel.backgroundColor = [UIColor redColor];
        vHeader.textLabel.textColor = [UIColor whiteColor];

        vHeader.contentView.backgroundColor = [UIColor redColor];
    }

    if (section == 0) {
        vHeader.textLabel.backgroundColor = [UIColor redColor];
        vHeader.textLabel.textColor = [UIColor whiteColor];


        vHeader.contentView.backgroundColor = [UIColor redColor];
    }

    else if (section == 1) {
        vHeader.textLabel.backgroundColor = [UIColor orangeColor];
        vHeader.textLabel.textColor = [UIColor blueColor];

        vHeader.contentView.backgroundColor = [UIColor orangeColor];
    }
    else if (section == 2) {
        vHeader.textLabel.backgroundColor = [UIColor yellowColor];
        vHeader.textLabel.textColor = [UIColor blueColor];

        vHeader.contentView.backgroundColor = [UIColor yellowColor];
    }
    else if (section == 3) {
        vHeader.textLabel.backgroundColor = [UIColor magentaColor];
        vHeader.textLabel.textColor = [UIColor whiteColor];

        vHeader.contentView.backgroundColor = [UIColor magentaColor];
    }
    else if (section == 4) {
        vHeader.textLabel.backgroundColor = [UIColor blueColor];
        vHeader.textLabel.textColor = [UIColor whiteColor];

        vHeader.contentView.backgroundColor = [UIColor blueColor];
    }
    else if (section == 5) {
        vHeader.textLabel.backgroundColor = [UIColor darkGrayColor];
        vHeader.textLabel.textColor = [UIColor whiteColor];

        vHeader.contentView.backgroundColor = [UIColor darkGrayColor];
    }

    vHeader.textLabel.text = [self tableView:tableView titleForHeaderInSection:section];


    UIView *mView = [[UIView alloc]initWithFrame:CGRectMake(10.0f, 0.0f, 300.0f, 44.0f)];
    [mView setBackgroundColor:[UIColor clearColor]];

    UIImageView *logoView = [[UIImageView alloc]initWithFrame:CGRectMake(0, 5, 20, 20)];
    [logoView setImage:[UIImage imageNamed:@"carat.png"]];
    [mView addSubview:logoView];

    UIButton *bt = [UIButton buttonWithType:UIButtonTypeCustom];
    [bt setFrame:CGRectMake(210, 0, 150, 30)];
    [bt setTitleColor:[UIColor blueColor] forState:UIControlStateNormal];
    [bt setTag:section];
    [bt.titleLabel setFont:[UIFont systemFontOfSize:20]];
    [bt.titleLabel setTextAlignment:NSTextAlignmentCenter];
    [bt.titleLabel setTextColor:[UIColor blackColor]];
    [bt setTitle: @"More Info" forState: UIControlStateNormal];
    [bt addTarget:self action:@selector(addCell:) forControlEvents:UIControlEventTouchUpInside];
    [mView addSubview:bt];
    return mView;

    return vHeader;

}

我应该怎么做才能保留部分标题并显示按钮。节标题在 titleForHeaderInSection 方法中定义？

你的问题是你的按钮太大了。尝试减小它的高度和字体大小，它应该可以工作。您还可以使用以下方法增加节标题的高度:

- (CGFloat)tableView:(UITableView *)tableView heightForHeaderInSection:(NSInteger)section {
    return 30;
}

编辑:你可以像这样实现你的行为:

//create the regular section header
if (regularHeader) {
    UIView *headerView = [[UIView alloc] initWithFrame:CGRectMake(0, 0, 320, 28)];
    UILabel *titleLabel = [[UILabel alloc] initWithFrame:CGRectMake(4, 5, 300, 20)];
    titleLabel.text = title;
    [headerView addSubview:titleLabel];
    return headerView;
}

//create the header with the more button
UIView *headerView = [[UIView alloc] initWithFrame:CGRectMake(0, 0, 320, 44)];
UIButton *moreButton = [[UIButton alloc] initWithFrame:CGRectMake(210, 0, 50, 30)];
moreButton.titleLabel.text = @"More";
[headerView addSubview:moreButton];
return headerView;
