我认为你在正确的轨道上，但根据selectedBackgroundView的类定义:

对于普通样式表(UITableViewStylePlain)中的单元格，默认为nil，对于section-group表(UITableViewStyleGrouped)中的单元格，默认为非nil。

因此，如果你使用的是普通样式的表，那么你需要alloc-init一个新的UIView，有你想要的背景颜色，然后分配给selectedBackgroundView。

或者，如果你想要的是灰色背景当单元格被选中时，你可以使用这个:

cell.selectionStyle = UITableViewCellSelectionStyleGray;

我想指出的是，XIB编辑器为您提供了以下标准选项:

部分:蓝色/灰色/没有

(右边有选项的列，第4个标签，第一组“表格视图单元格”，第4个子组，3个项目中的第一个读为“选择”)

也许你想做的事情可以通过选择正确的标准选项来实现。

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

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”

I've got a slightly different approach than everyone else that reflects the selection on touch rather than after being selected. I have a subclassed UITableViewCell. All you have to do is set the background color in the touch events, which simulates selection on touch, and then set the background color in the setSelected function. Setting the background color in the selSelected function allows for deselecting the cell. Make sure to pass the touch event to the super, otherwise the cell won't actually act as if its selected.

override func touchesBegan(touches: NSSet, withEvent event: UIEvent) {
    self.backgroundColor = UIColor(white: 0.0, alpha: 0.1)
    super.touchesBegan(touches, withEvent: event)
}

override func touchesCancelled(touches: NSSet!, withEvent event: UIEvent!) {
    self.backgroundColor = UIColor.clearColor()
    super.touchesCancelled(touches, withEvent: event)
}

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

    // Configure the view for the selected state
    self.backgroundColor = selected ? UIColor(white: 0.0, alpha: 0.1) : UIColor.clearColor()
}

不需要自定义单元格。如果你只想改变单元格的选定颜色，你可以这样做:

objective - c:

UIView *bgColorView = [[UIView alloc] init];
bgColorView.backgroundColor = [UIColor redColor];
[cell setSelectedBackgroundView:bgColorView];

迅速:

let bgColorView = UIView()
bgColorView.backgroundColor = UIColor.red
cell.selectedBackgroundView = bgColorView
