如何模仿 UITableView 的 UITableViewStylePlain 部分标题样式 [英] How to mimic UITableView's UITableViewStylePlain section header style

问题描述

我的应用程序在 UITableView 部分标题标题中使用了 VoiceOver 难以发音的缩写.因为我需要让 VoiceOver 能够发音这些标题，所以我需要给部分标题标题一个 accessibilityLabel.

My application uses abbreviations in UITableView section header titles that are hard for VoiceOver to pronounce. As I need to make these titles pronounceable by VoiceOver, I need to give the section header title a accessibilityLabel.

似乎这样做的唯一方法是绘制自定义部分标题单元格.我想模仿 Apple UIKit 为这些自定义部分标题提供的标准样式，但我不确定如何模拟 Apple 对该元素的详细外观.

It seems that the only way to do this is to draw a custom section header cell. I would like to mimic the standard Apple UIKit provided style for these custom section headers but I am uncertain on how to emulate Apple's detailed look of this element.

模仿 UITableViewStylePlain 部分标题样式的最佳方法是什么?

What is the best approach to mimic the UITableViewStylePlain section header style?

更新:我很清楚如何创建自定义标题单元格.我正在寻找的是一种完全模仿 Apple 为普通 UITableView 部分标题单元格提供的标题单元格样式外观的技术.

Update: I am well aware how to create a custom header cell. What I am looking for is a technique to mimic exactly the look of the header cell style as provided by Apple for the plain UITableView section header cells.

推荐答案

如果有人仍然感兴趣，我用下面的代码看起来非常接近(使用上面评论中的 Mark Adams 图像，但我调整了它们的大小稍微因为我的应用也有横向模式):

If anyone is still interested, I've got it looking pretty damn close with the following code (using Mark Adams images from the comment above, but I resized them slightly as my app also has landscape mode):

- (UIView *)tableView:(UITableView *)tbl viewForHeaderInSection:(NSInteger)section
{
    UIView* sectionHead = [[UIView alloc] initWithFrame:CGRectMake(0, 0, tbl.bounds.size.width, 18)];
    sectionHead.backgroundColor = [UIColor colorWithWhite:0 alpha:0];
    sectionHead.userInteractionEnabled = YES;
    sectionHead.tag = section;

    UIImageView *headerImage = [[UIImageView alloc] initWithImage:[UIImage imageNamed:@"PlainTableViewSectionHeader.png"]];
    headerImage.contentMode = UIViewContentModeScaleAspectFit;

    [sectionHead addSubview:headerImage];
    [headerImage release];

    UILabel *sectionText = [[UILabel alloc] initWithFrame:CGRectMake(10, 2, tbl.bounds.size.width - 10, 18)];
    sectionText.text = text;
    sectionText.backgroundColor = [UIColor clearColor];
    sectionText.textColor = [UIColor whiteColor];
    sectionText.shadowColor = [UIColor darkGrayColor];
    sectionText.shadowOffset = CGSizeMake(0,1);
    sectionText.font = [UIFont boldSystemFontOfSize:18];

    [sectionHead addSubview:sectionText];
    [sectionText release];

    return [sectionHead autorelease];
}
