以下是我在iOS 8中使用的。

我必须将选择样式设置为UITableViewCellSelectionStyleDefault，以便自定义背景色能够工作。如果有其他样式，自定义背景色将被忽略。在行为上似乎有一个变化，因为以前的答案需要将style设置为none。

单元格的完整代码如下:

- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {
    static NSString *CellIdentifier = @"MyCell";
    UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
    if (cell == nil) {
        cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier];
    }

    // This is how you change the background color
    cell.selectionStyle = UITableViewCellSelectionStyleDefault;
    UIView *bgColorView = [[UIView alloc] init];
    bgColorView.backgroundColor = [UIColor redColor];
    [cell setSelectedBackgroundView:bgColorView];        
    return cell;
}

覆盖UITableViewCell的setSelected也可以。

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

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

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

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()
}

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。

在自定义单元格类中为表单元格创建一个自定义单元格。M把下面的代码，它会工作的很好。你需要把想要的颜色图像放在选择背景UIImage中。

- (void)setSelected:(BOOL)selected animated:(BOOL)animated
{
    UIImage *selectionBackground = [UIImage imageNamed:@"yellow_bar.png"];
    UIImageView *iview=[[UIImageView alloc] initWithImage:selectionBackground];
    self.selectedBackgroundView=iview;
}
