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;
}

#pragma mark Table view delegate

- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
{
    NSIndexPath *path = [NSIndexPath indexPathForRow:0 inSection:[indexPath section]];
    UITableViewCell *cell = [tableView cellForRowAtIndexPath:path];
    [cell setSelectionStyle:UITableViewCellSelectionStyleBlue];

    [tableView selectRowAtIndexPath:path animated:YES scrollPosition:UITableViewScrollPositionNone];

}

- (void)tableView:(UITableView *)tableView didDeselectRowAtIndexPath:(NSIndexPath *)indexPath
{
    UITableViewCell *cell = [tvStat cellForRowAtIndexPath:indexPath];
    [cell setSelectionStyle:UITableViewCellSelectionStyleNone];
}

#pragma mark Table view Gestures

-(IBAction)singleTapFrom:(UIGestureRecognizer *)tapRecog
{

    CGPoint tapLoc = [tapRecog locationInView:tvStat];
    NSIndexPath *tapPath = [tvStat indexPathForRowAtPoint:tapLoc];

    NSIndexPath *seleRow = [tvStat indexPathForSelectedRow];
    if([seleRow section] != [tapPath section])
        [self tableView:tvStat didDeselectRowAtIndexPath:seleRow];
    else if (seleRow == nil )
        {}
    else if([seleRow section] == [tapPath section] || [seleRow length] != 0)
        return;

    if(!tapPath)
        [self.view endEditing:YES];

    [self tableView:tvStat didSelectRowAtIndexPath:tapPath];
}

如果您想向单元格添加自定义高亮显示的颜色(且单元格包含按钮、标签、图像等)。我按照下面的步骤:

例如，如果你想要一个选定的黄色:

1)创建一个适合所有不透明度为20%的单元格(黄色)的视图，例如backgroundselectedView

2)在单元控制器中这样写:

- (void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event
{
     self.backgroundselectedView.alpha=1;
    [super touchesBegan:touches withEvent:event];
}

- (void)touchesEnded:(NSSet *)touches withEvent:(UIEvent *)event
{
    self.backgroundselectedView.alpha=0;
    [super touchesEnded:touches withEvent:event];
}

- (void)touchesCancelled:(NSSet *)touches withEvent:(UIEvent *)event
{
    self.backgroundSelectedImage.alpha=0;
    [super touchesCancelled:touches withEvent:event];
}

根据UITableView中选定单元格的自定义颜色，根据Maciej Swic的答案，很棒的解决方案

为了补充这一点，你在Cell配置中声明Swic的答案通常如下:

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

为了增加效果，您可以使用RGB值来实现自定义颜色外观，而不是系统颜色。在我的代码中，我是这样实现的:

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

} 

 static NSString *CellIdentifier = @"YourCustomCellName";
 MakanTableCell *cell = [self.tableView dequeueReusableCellWithIdentifier:CellIdentifier forIndexPath:indexPath];

// Configure the cell...

if (cell == nil) {

cell = [[[NSBundle mainBundle]loadNibNamed:@"YourCustomCellClassName" owner:self options:nil]objectAtIndex:0];
                    } 

UIView *bgColorView = [[UIView alloc] init];
bgColorView.backgroundColor = [UIColor colorWithRed:255.0/256.0 green:239.0/256.0 blue:49.0/256.0 alpha:1];
bgColorView.layer.cornerRadius = 7;
bgColorView.layer.masksToBounds = YES;
[cell setSelectedBackgroundView:bgColorView];


return cell;

}

如果这对你也有用，请告诉我。你可以在选定单元格的角落上打乱拐角半径的数值。

对于Swift 3.0:

override func tableView(_ tableView: UITableView, didSelectRowAt indexPath: IndexPath) {
    let cell = super.tableView(tableView, cellForRowAt: indexPath)

    cell.contentView.backgroundColor = UIColor.red
}

- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
{
    [tableView reloadData];
    UITableViewCell *cell=(UITableViewCell*)[tableView cellForRowAtIndexPath:indexPath];
    [cell setBackgroundColor:[UIColor orangeColor]];
}

[cell setSelectionStyle:UITableViewCellSelectionStyleGray];

确保你已经使用了上面的行来使用选择效果
