下面是分组表所需的代码的重要部分。当一个部分中的任何单元格被选中时，第一行将改变颜色。如果没有最初设置cellselectionstyle为none，当用户单击row0时，单元格更改为bgColorView，然后淡入并重新加载bgColorView时，会出现恼人的双重重载。祝你好运，如果有更简单的方法，请告诉我。

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

    static NSString *CellIdentifier = @"Cell";

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

    if ([indexPath row] == 0) 
    {
        cell.selectionStyle = UITableViewCellSelectionStyleNone;

        UIView *bgColorView = [[UIView alloc] init];
        bgColorView.layer.cornerRadius = 7;
        bgColorView.layer.masksToBounds = YES;
        [bgColorView setBackgroundColor:[UIColor colorWithRed:.85 green:0 blue:0 alpha:1]];
        [cell setSelectedBackgroundView:bgColorView];

        UIColor *backColor = [UIColor colorWithRed:0 green:0 blue:1 alpha:1];
        cell.backgroundColor = backColor;
        UIColor *foreColor = [UIColor colorWithWhite:1 alpha:1];
        cell.textLabel.textColor = foreColor;

        cell.textLabel.text = @"row0";
    }
    else if ([indexPath row] == 1) 
    {
        cell.selectionStyle = UITableViewCellSelectionStyleNone;

        UIColor *backColor = [UIColor colorWithRed:1 green:1 blue:1 alpha:1];
        cell.backgroundColor = backColor;
        UIColor *foreColor = [UIColor colorWithRed:0 green:0 blue:0 alpha:1];
        cell.textLabel.textColor = foreColor;

        cell.textLabel.text = @"row1";
    }
    else if ([indexPath row] == 2) 
    {
        cell.selectionStyle = UITableViewCellSelectionStyleNone;

        UIColor *backColor = [UIColor colorWithRed:1 green:1 blue:1 alpha:1];
        cell.backgroundColor = backColor;
        UIColor *foreColor = [UIColor colorWithRed:0 green:0 blue:0 alpha:1];
        cell.textLabel.textColor = foreColor;

        cell.textLabel.text = @"row2";
    }
    return cell;
}

Swift 5 - Xcode版本12.1 (12A7403)

| |第一步 将以下内容添加到AppDelegate.swift文件中

func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey: Any]?) -> Bool {

    let colorView = UIView()
    colorView.backgroundColor = UIColor.lightGray

    UITableViewCell.appearance().selectedBackgroundView = colorView
        
    return true
}

|第二步| 确保在属性检查器中，单元格的内容视图背景设置为“清除颜色”(而不是“默认”)。这样做是为了不与App Delegate设置冲突。

我使用的是ios9.3，通过Storyboard或设置单元格设置颜色。selectionStyle不适合我，但下面的代码工作:

UIView *customColorView = [[UIView alloc] init];
customColorView.backgroundColor = [UIColor colorWithRed:55 / 255.0 
                                                  green:141 / 255.0 
                                                   blue:211 / 255.0 
                                                  alpha:1.0];
cell.selectedBackgroundView = customColorView;

return cell;

我找到了这个解。

快4.倍

要改变选择背景颜色为任何颜色使用Swift扩展

创建UITableView Cell扩展，如下所示

extension UITableViewCell{

    func removeCellSelectionColour(){
        let clearView = UIView()
        clearView.backgroundColor = UIColor.clear
        UITableViewCell.appearance().selectedBackgroundView = clearView
    } 

}

然后用单元格实例调用removeCellSelectionColour()。

如果你有一个分组表，每个部分只有一个单元格，只需在代码中添加额外的一行: bgColorView.layer.cornerRadius = 10;

UIView *bgColorView = [[UIView alloc] init];
[bgColorView setBackgroundColor:[UIColor redColor]];
bgColorView.layer.cornerRadius = 10;
[cell setSelectedBackgroundView:bgColorView];
[bgColorView release]; 

不要忘记导入QuartzCore。

再一个提示基督教的方式显示圆角背景分组表。

如果我为单元格使用cornerRadius = 10，它会显示四个角的圆角选择背景。这和表格视图的默认UI不一样。

所以，我想用简单的方法来解决它。 正如你可以从下面的代码中看到的，检查单元格的位置(顶部，底部，中间或顶部底部)，并添加更多的子层来隐藏顶部角或底部角。这只是显示了与默认表视图的选择背景完全相同的外观。

我用iPad splitterview测试了这段代码。你可以根据需要改变patchLayer的帧位置。

请让我知道是否有更简单的方法来达到同样的效果。

if (tableView.style == UITableViewStyleGrouped) 
{
    if (indexPath.row == 0) 
    {
        cellPosition = CellGroupPositionAtTop;
    }    
    else 
    {
        cellPosition = CellGroupPositionAtMiddle;
    }

    NSInteger numberOfRows = [tableView numberOfRowsInSection:indexPath.section];
    if (indexPath.row == numberOfRows - 1) 
    {
        if (cellPosition == CellGroupPositionAtTop) 
        {
            cellPosition = CellGroupPositionAtTopAndBottom;
        } 
        else 
        {
            cellPosition = CellGroupPositionAtBottom;
        }
    }

    if (cellPosition != CellGroupPositionAtMiddle) 
    {
        bgColorView.layer.cornerRadius = 10;
        CALayer *patchLayer;
        if (cellPosition == CellGroupPositionAtTop) 
        {
            patchLayer = [CALayer layer];
            patchLayer.frame = CGRectMake(0, 10, 302, 35);
            patchLayer.backgroundColor = YOUR_BACKGROUND_COLOR;
            [bgColorView.layer addSublayer:patchLayer];
        } 
        else if (cellPosition == CellGroupPositionAtBottom) 
        {
            patchLayer = [CALayer layer];
            patchLayer.frame = CGRectMake(0, 0, 302, 35);
            patchLayer.backgroundColor = YOUR_BACKGROUND_COLOR;
            [bgColorView.layer addSublayer:patchLayer];
        }
    }
}
