我已经创建了一个自定义UITableViewCell。表视图很好地显示了数据。我陷入的是当用户触摸tableview的单元格时,然后我想显示单元格的背景颜色,而不是默认的[蓝色]值,以突出显示单元格的选择。 我使用这段代码,但什么都没有发生:

cell.selectedBackgroundView.backgroundColor=[UIColor blackColor];

当前回答

下面是分组表所需的代码的重要部分。当一个部分中的任何单元格被选中时,第一行将改变颜色。如果没有最初设置cellselectionstyle为none,当用户单击row0时,单元格更改为bgColorView,然后淡入并重新加载bgColorView时,会出现恼人的双重重载。祝你好运,如果有更简单的方法,请告诉我。

- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath 
{

    static NSString *CellIdentifier = @"Cell";

    UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
    if (cell == nil) {
        cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier];
    }

    if ([indexPath row] == 0) 
    {
        cell.selectionStyle = UITableViewCellSelectionStyleNone;

        UIView *bgColorView = [[UIView alloc] init];
        bgColorView.layer.cornerRadius = 7;
        bgColorView.layer.masksToBounds = YES;
        [bgColorView setBackgroundColor:[UIColor colorWithRed:.85 green:0 blue:0 alpha:1]];
        [cell setSelectedBackgroundView:bgColorView];

        UIColor *backColor = [UIColor colorWithRed:0 green:0 blue:1 alpha:1];
        cell.backgroundColor = backColor;
        UIColor *foreColor = [UIColor colorWithWhite:1 alpha:1];
        cell.textLabel.textColor = foreColor;

        cell.textLabel.text = @"row0";
    }
    else if ([indexPath row] == 1) 
    {
        cell.selectionStyle = UITableViewCellSelectionStyleNone;

        UIColor *backColor = [UIColor colorWithRed:1 green:1 blue:1 alpha:1];
        cell.backgroundColor = backColor;
        UIColor *foreColor = [UIColor colorWithRed:0 green:0 blue:0 alpha:1];
        cell.textLabel.textColor = foreColor;

        cell.textLabel.text = @"row1";
    }
    else if ([indexPath row] == 2) 
    {
        cell.selectionStyle = UITableViewCellSelectionStyleNone;

        UIColor *backColor = [UIColor colorWithRed:1 green:1 blue:1 alpha:1];
        cell.backgroundColor = backColor;
        UIColor *foreColor = [UIColor colorWithRed:0 green:0 blue:0 alpha:1];
        cell.textLabel.textColor = foreColor;

        cell.textLabel.text = @"row2";
    }
    return cell;
}

#pragma mark Table view delegate

- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
{
    NSIndexPath *path = [NSIndexPath indexPathForRow:0 inSection:[indexPath section]];
    UITableViewCell *cell = [tableView cellForRowAtIndexPath:path];
    [cell setSelectionStyle:UITableViewCellSelectionStyleBlue];

    [tableView selectRowAtIndexPath:path animated:YES scrollPosition:UITableViewScrollPositionNone];

}

- (void)tableView:(UITableView *)tableView didDeselectRowAtIndexPath:(NSIndexPath *)indexPath
{
    UITableViewCell *cell = [tvStat cellForRowAtIndexPath:indexPath];
    [cell setSelectionStyle:UITableViewCellSelectionStyleNone];
}

#pragma mark Table view Gestures

-(IBAction)singleTapFrom:(UIGestureRecognizer *)tapRecog
{

    CGPoint tapLoc = [tapRecog locationInView:tvStat];
    NSIndexPath *tapPath = [tvStat indexPathForRowAtPoint:tapLoc];

    NSIndexPath *seleRow = [tvStat indexPathForSelectedRow];
    if([seleRow section] != [tapPath section])
        [self tableView:tvStat didDeselectRowAtIndexPath:seleRow];
    else if (seleRow == nil )
        {}
    else if([seleRow section] == [tapPath section] || [seleRow length] != 0)
        return;

    if(!tapPath)
        [self.view endEditing:YES];

    [self tableView:tvStat didSelectRowAtIndexPath:tapPath];
}

我使用下面的方法,对我来说很好,

class MyTableViewCell : UITableViewCell {

                var defaultStateColor:UIColor?
                var hitStateColor:UIColor?

                 override func awakeFromNib(){
                     super.awakeFromNib()
                     self.selectionStyle = .None
                 }

// if you are overriding init you should set selectionStyle = .None

                override func touchesBegan(touches: Set<UITouch>, withEvent event: UIEvent?) {
                    if let hitColor = hitStateColor {
                        self.contentView.backgroundColor = hitColor
                    }
                }

                override func touchesEnded(touches: Set<UITouch>, withEvent event: UIEvent?) {
                    if let defaultColor = defaultStateColor {
                        self.contentView.backgroundColor = defaultColor
                    }
                }

                override func touchesCancelled(touches: Set<UITouch>?, withEvent event: UIEvent?) {
                    if let defaultColor = defaultStateColor {
                        self.contentView.backgroundColor = defaultColor
                    }
                }
            }
[cell setSelectionStyle:UITableViewCellSelectionStyleGray];

确保你已经使用了上面的行来使用选择效果

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

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;
}

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()
}
