在UITableViewCell中更改附件视图的背景

根据UITableViewCell，它由两部分组成：

我为附件视图设置了自定义图像：

func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell {
    let cell = tableView.dequeueReusableCellWithIdentifier("settingCell") as! SettingsTableViewCell
    cell.setCellColor(self.items[indexPath.row])
    let img = UIImage(named: "icon-right-arrow")!
    let imgView:UIImageView = UIImageView()
    imgView.contentMode = UIViewContentMode.ScaleAspectFill
    imgView.frame.size.width = img.size.width
    imgView.frame.size.height = img.size.height
    imgView.image = img
    imgView.image = imgView.image!.imageWithRenderingMode(UIImageRenderingMode.AlwaysTemplate)
    imgView.tintColor = UIColor.orangeColor()
    cell.accessoryView = imgView

    return cell
}

func tableView(tableView: UITableView, didSelectRowAtIndexPath indexPath: NSIndexPath) {
    let selectedCell = tableView.cellForRowAtIndexPath(indexPath) as! SettingsTableViewCell
    selectedCell.setSelectedColor()
    let img = UIImage(named: "icon-right-arrow")!
    let imgView:UIImageView = UIImageView()
    imgView.contentMode = UIViewContentMode.Center
    imgView.frame.size.width = selectedCell.accessoryView!.frame.width
    imgView.frame.size.height = selectedCell.accessoryView!.frame.height
    imgView.backgroundColor = UIColor.orangeColor()
    imgView.image = img
    imgView.image = imgView.image!.imageWithRenderingMode(UIImageRenderingMode.AlwaysTemplate)
    imgView.tintColor = UIColor.whiteColor()
    selectedCell.accessoryView = imgView

    selectedCell.contentView.backgroundColor = UIColor.orangeColor()

}

当选定单元格时触发的函数：

func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell {
    let cell = tableView.dequeueReusableCellWithIdentifier("settingCell") as! SettingsTableViewCell
    cell.setCellColor(self.items[indexPath.row])
    let img = UIImage(named: "icon-right-arrow")!
    let imgView:UIImageView = UIImageView()
    imgView.contentMode = UIViewContentMode.ScaleAspectFill
    imgView.frame.size.width = img.size.width
    imgView.frame.size.height = img.size.height
    imgView.image = img
    imgView.image = imgView.image!.imageWithRenderingMode(UIImageRenderingMode.AlwaysTemplate)
    imgView.tintColor = UIColor.orangeColor()
    cell.accessoryView = imgView

    return cell
}

func tableView(tableView: UITableView, didSelectRowAtIndexPath indexPath: NSIndexPath) {
    let selectedCell = tableView.cellForRowAtIndexPath(indexPath) as! SettingsTableViewCell
    selectedCell.setSelectedColor()
    let img = UIImage(named: "icon-right-arrow")!
    let imgView:UIImageView = UIImageView()
    imgView.contentMode = UIViewContentMode.Center
    imgView.frame.size.width = selectedCell.accessoryView!.frame.width
    imgView.frame.size.height = selectedCell.accessoryView!.frame.height
    imgView.backgroundColor = UIColor.orangeColor()
    imgView.image = img
    imgView.image = imgView.image!.imageWithRenderingMode(UIImageRenderingMode.AlwaysTemplate)
    imgView.tintColor = UIColor.whiteColor()
    selectedCell.accessoryView = imgView

    selectedCell.contentView.backgroundColor = UIColor.orangeColor()

}

对于取消选择的单元格：

func tableView(tableView: UITableView, didDeselectRowAtIndexPath indexPath: NSIndexPath) {
    let selectedCell = tableView.cellForRowAtIndexPath(indexPath) as! SettingsTableViewCell
    selectedCell.setDeSelectedColor()
    let img = UIImage(named: "icon-right-arrow")!
    let imgView:UIImageView = UIImageView()
    imgView.contentMode = UIViewContentMode.Center
    imgView.frame.size.width = selectedCell.accessoryView!.frame.width
    imgView.frame.size.height = selectedCell.accessoryView!.frame.height
    imgView.backgroundColor = UIColor.clearColor()
    imgView.image = img
    imgView.image = imgView.image!.imageWithRenderingMode(UIImageRenderingMode.AlwaysTemplate)
    imgView.tintColor = UIColor.orangeColor()
    selectedCell.accessoryView = imgView

}

但结果不是我想要的，附件视图仍有灰色背景，但我希望它是橙色的：

您必须使用

UITableViewCellSelectionStyle.None将取消选择的单元格选择样式设置为无

func tableView(tableView: UITableView, didDeselectRowAtIndexPath indexPath: NSIndexPath) {
    let selectedCell = tableView.cellForRowAtIndexPath(indexPath) as! SettingsTableViewCell
    selectedCell.selectionStyle = UITableViewCellSelectionStyle.None
    selectedCell.setDeSelectedColor()
    let img = UIImage(named: "icon-right-arrow")!
    let imgView:UIImageView = UIImageView()
    imgView.contentMode = UIViewContentMode.Center
    imgView.frame.size.width = selectedCell.accessoryView!.frame.width
    imgView.frame.size.height = selectedCell.accessoryView!.frame.height
    imgView.backgroundColor = UIColor.clearColor()
    imgView.image = img
    imgView.image = imgView.image!.imageWithRenderingMode(UIImageRenderingMode.AlwaysTemplate)
    imgView.tintColor = UIColor.orangeColor()
    selectedCell.accessoryView = imgView

}

当您自己更改所选单元格的背景时，可以将选择样式设置为“无”，而不是灰色或蓝色。
selectedCell.selectionStyle=UITableViewCellSelectionStyle.None
应在
selectedCell.contentView.superview？.backgroundColor=UIColor.orangeColor（）之前设置
我猜selectedCell.setDeceledColor（）这没有用吗？
