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

Swift 3.0扩展

extension UITableViewCell {
    var selectionColor: UIColor {
        set {
            let view = UIView()
            view.backgroundColor = newValue
            self.selectedBackgroundView = view
        }
        get {
            return self.selectedBackgroundView?.backgroundColor ?? UIColor.clear
        }
    }
}

细胞。selectionColor = uiccolor . formacar .blue

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];
}

为所有单元格添加背景(使用Maciej的答案):

for (int section = 0; section < [self.tableView numberOfSections]; section++) {
        for (int row = 0; row < [self.tableView numberOfRowsInSection:section]; row++) {
            NSIndexPath* cellPath = [NSIndexPath indexPathForRow:row inSection:section];
            UITableViewCell* cell = [self.tableView cellForRowAtIndexPath:cellPath];

            //stuff to do with each cell
            UIView *bgColorView = [[UIView alloc] init];
            bgColorView.backgroundColor = [UIColor redColor];
            [cell setSelectedBackgroundView:bgColorView];
        }
    } 

快4.倍

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()。

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];
}
-(void)tableView:(UITableView *)tableView willDisplayCell:(UITableViewCell *)cell forRowAtIndexPath:(NSIndexPath *)indexPath
{
    UIView *view = [[UIView alloc] init];
    [view setBackgroundColor:[UIColor redColor]];
    [cell setSelectedBackgroundView:view];
}

我们需要在这个方法中设置所选的背景视图。
