Objectivec 在 Interface Builder 中设计 UITableView 的section header

我有一个带有UITableView的xib文件，我想使用委托方法tableView:viewForHeaderInSection:为其添加一个自定义的节头视图.有没有可能在Interface Builder中设计它，然后以编程方式更改它的一些子视图属性？

我的UITableView有更多的节头，所以在Interface Builder中创建一个UIView并返回它是不起作用的，因为我必须复制它，但没有任何好的方法来做它.归档和取消归档它对UIImage不起作用，所以UIImageView会显示为空白.

此外，我不想以编程的方式创建它们，因为它们太复杂，生成的代码很难读取和维护.

Edit 1:以下是我的tableView:viewForHeaderInSection:种方法:

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

    if ([tableView.dataSource tableView:tableView numberOfRowsInSection:section] == 0) {
        return nil;
    }

    CGSize headerSize = CGSizeMake(self.view.frame.size.width, 100);

    /* wrapper */

    UIView *wrapperView = [UIView viewWithSize:headerSize];

    wrapperView.backgroundColor = [UIColor colorWithHexString:@"2670ce"];

    /* title */

    CGPoint titleMargin = CGPointMake(15, 8);

    UILabel *titleLabel = [UILabel labelWithText:self.categoriesNames[section] andFrame:CGEasyRectMake(titleMargin, CGSizeMake(headerSize.width - titleMargin.x * 2, 20))];

    titleLabel.textColor = [UIColor whiteColor];
    titleLabel.font = [UIFont fontWithStyle:FontStyleRegular andSize:14];

    [wrapperView addSubview:titleLabel];

    /* body wrapper */

    CGPoint bodyWrapperMargin = CGPointMake(10, 8);

    CGPoint bodyWrapperViewOrigin = CGPointMake(bodyWrapperMargin.x, CGRectGetMaxY(titleLabel.frame) + bodyWrapperMargin.y);
    CGSize bodyWrapperViewSize = CGSizeMake(headerSize.width - bodyWrapperMargin.x * 2, headerSize.height - bodyWrapperViewOrigin.y - bodyWrapperMargin.y);

    UIView *bodyWrapperView = [UIView viewWithFrame:CGEasyRectMake(bodyWrapperViewOrigin, bodyWrapperViewSize)];

    [wrapperView addSubview:bodyWrapperView];

    /* image */

    NSInteger imageSize = 56;
    NSString *imageName = [self getCategoryResourceItem:section + 1][@"image"];

    UIImageView *imageView = [UIImageView imageViewWithImage:[UIImage imageNamed:imageName] andFrame:CGEasyRectMake(CGPointZero, CGEqualSizeMake(imageSize))];

    imageView.layer.masksToBounds = YES;
    imageView.layer.cornerRadius = imageSize / 2;

    [bodyWrapperView addSubview:imageView];

    /* labels */

    NSInteger labelsWidth = 60;

    UILabel *firstLabel = [UILabel labelWithText:@"first" andFrame:CGRectMake(imageSize + bodyWrapperMargin.x, 0, labelsWidth, 16)];

    [bodyWrapperView addSubview:firstLabel];

    UILabel *secondLabel = [UILabel labelWithText:@"second" andFrame:CGRectMake(imageSize + bodyWrapperMargin.x, 20, labelsWidth, 16)];

    [bodyWrapperView addSubview:secondLabel];

    UILabel *thirdLabel = [UILabel labelWithText:@"third" andFrame:CGRectMake(imageSize + bodyWrapperMargin.x, 40, labelsWidth, 16)];

    [bodyWrapperView addSubview:thirdLabel];

    [@[ firstLabel, secondLabel, thirdLabel ] forEachView:^(UIView *view) {
        UILabel *label = (UILabel *)view;

        label.textColor = [UIColor whiteColor];
        label.font = [UIFont fontWithStyle:FontStyleLight andSize:11];
    }];

    /* line */

    UIView *lineView = [UIView viewWithFrame:CGRectMake(imageSize + labelsWidth + bodyWrapperMargin.x * 2, bodyWrapperMargin.y, 1, bodyWrapperView.frame.size.height - bodyWrapperMargin.y * 2)];

    lineView.backgroundColor = [UIColor whiteColorWithAlpha:0.2];

    [bodyWrapperView addSubview:lineView];

    /* progress */

    CGPoint progressSliderOrigin = CGPointMake(imageSize + labelsWidth + bodyWrapperMargin.x * 3 + 1, bodyWrapperView.frame.size.height / 2 - 15);
    CGSize progressSliderSize = CGSizeMake(bodyWrapperViewSize.width - bodyWrapperMargin.x - progressSliderOrigin.x, 30);

    UISlider *progressSlider = [UISlider viewWithFrame:CGEasyRectMake(progressSliderOrigin, progressSliderSize)];

    progressSlider.value = [self getCategoryProgress];

    [bodyWrapperView addSubview:progressSlider];

    return wrapperView;
}

我希望它看起来像这样:

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

    if ([tableView.dataSource tableView:tableView numberOfRowsInSection:section] == 0) {
        return nil;
    }

    SectionView *sectionView = ... // get the view that is already designed in the Interface Builder

    sectionView.headerText = self.categoriesNames[section];
    sectionView.headerImage = [self getCategoryResourceItem:section + 1][@"image"];

    sectionView.firstLabelText = @"first";
    sectionView.secondLabelText = @"second";
    sectionView.thirdLabelText = @"third";

    sectionView.progress = [self getCategoryProgress];

    return wrapperView;
}

Edit 2:我用的不是Storyboard，而是.xib个文件.此外，我没有UITableViewController，只有UIViewController，其中我加了UITableView.
