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()。

使用[cell setClipsToBounds:YES];对于分组样式单元格

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()
}

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。

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

    }

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
