1-添加一个视图到单元格的内容视图。 2-右击你的单元格。 3-使添加的视图为“selectedBackgroundView”

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

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
}

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()。

单元格选择的背景颜色可以通过界面构建器中的Storyboard设置:

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
}
