当表视图样式是普通的，这很容易，但在组样式，这是一个小麻烦，我解决它:

CGFloat cellHeight = [self tableView:tableView heightForRowAtIndexPath:indexPath];
UIView *view = [[UIView alloc] initWithFrame:CGRectMake(0, 0, kGroupTableViewCellWidth+2, cellHeight)];
view.backgroundColor = kCommonHighlightedColor;
cell.selectedBackgroundView = view;
[view release];
UIRectCorner cornerFlag = 0;
CGSize radii = CGSizeMake(0, 0);
NSInteger theLastRow = --> (yourDataSourceArray.count - 1);
if (indexPath.row == 0) {
    cornerFlag = UIRectCornerTopLeft | UIRectCornerTopRight;
    radii = CGSizeMake(10, 10);
} else if (indexPath.row == theLastRow) {
    cornerFlag = UIRectCornerBottomLeft | UIRectCornerBottomRight;
    radii = CGSizeMake(10, 10);
}
UIBezierPath *maskPath = [UIBezierPath bezierPathWithRoundedRect:view.bounds byRoundingCorners:cornerFlag cornerRadii:radii];
CAShapeLayer *shapeLayer = [CAShapeLayer layer];
shapeLayer.path = maskPath.CGPath;
view.layer.mask = shapeLayer;

注意到kGroupTableViewCellWidth，我把它定义为300，这是iPhone中组表视图单元格的宽度

如果你正在使用一个自定义的TableViewCell，你也可以覆盖awakeFromNib:

override func awakeFromNib() {
    super.awakeFromNib()

    // Set background color
    let view = UIView()
    view.backgroundColor = UIColor.redColor()
    selectedBackgroundView = view
}

试试下面的代码。

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

    UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:[cellIdArray objectAtIndex:indexPath.row] forIndexPath:indexPath];

    // Configure the cell...
    cell.backgroundView =
    [[UIImageView alloc] init] ;
    cell.selectedBackgroundView =[[UIImageView alloc] init];

    UIImage *rowBackground;
    UIImage *selectionBackground;


    rowBackground = [UIImage imageNamed:@"cellBackgroundDarkGrey.png"];
    selectionBackground = [UIImage imageNamed:@"selectedMenu.png"];

    ((UIImageView *)cell.backgroundView).image = rowBackground;
    ((UIImageView *)cell.selectedBackgroundView).image = selectionBackground;



    return cell;
}

/ /快速版:

func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {


        let cell = tableView.dequeueReusableCell(withIdentifier: "cell")! as UITableViewCell


        cell.selectedBackgroundView = UIImageView()
        cell.backgroundView=UIImageView()

        let selectedBackground : UIImageView = cell.selectedBackgroundView as! UIImageView
        selectedBackground.image = UIImage.init(named:"selected.png");

        let backGround : UIImageView = cell.backgroundView as! UIImageView
        backGround.image = UIImage.init(named:"defaultimage.png");

        return cell


    } 

override func setSelected(selected: Bool, animated: Bool) {
    // Configure the view for the selected state

    super.setSelected(selected, animated: animated)
    let selView = UIView()

    selView.backgroundColor = UIColor( red: 5/255, green: 159/255, blue:223/255, alpha: 1.0 )
    self.selectedBackgroundView = selView
}

自定义单元格类。覆盖:

- (void)setSelected:(BOOL)selected animated:(BOOL)animated {
    [super setSelected:selected animated:animated];

    // Configure the view for the selected state

    if (selected) {
        [self setBackgroundColor: CELL_SELECTED_BG_COLOR];
        [self.contentView setBackgroundColor: CELL_SELECTED_BG_COLOR];
    }else{
        [self setBackgroundColor: [UIColor clearColor]];
        [self.contentView setBackgroundColor: [UIColor clearColor]];
    }
}

斯威夫特4 +:

在表格单元格中添加以下行

let bgColorView = UIView()
bgColorView.backgroundColor =  .red
self.selectedBackgroundView = bgColorView

最后应该如下所示

override func setSelected(_ selected: Bool, animated: Bool)
    {
        super.setSelected(selected, animated: animated)

        // Configure the view for the selected state
        let bgColorView = UIView()
        bgColorView.backgroundColor =  .red
        self.selectedBackgroundView = bgColorView

    }
