Swift 3:对我来说，当你把它放在cellForRowAtIndexPath:方法中时，它就工作了

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

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

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。

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
}

在Swift 4中，你还可以全局设置你表格单元格的背景色(从这里取):

let backgroundColorView = UIView()
backgroundColorView.backgroundColor = UIColor.red
UITableViewCell.appearance().selectedBackgroundView = backgroundColorView

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];
}
