Swift:无法以编程方式编辑自定义表格单元格的属性 [英] Swift: Can't edit properties of custom table cell programmatically

问题描述

我正在尝试更改自定义表格单元格内视图的颜色，但是有一个插座，可以正常工作.我可以更改此视图的其他属性，例如.isHidden，但.backgroundColor似乎不起作用.知道我在做什么错吗?

I am trying to change the colour of a view inside a custom table cell and I have an outlet to it, which works. I can change other properties of this view, like .isHidden but .backgroundColor doesn't seem to work. Any idea what I'm doing wrong?

UIColor(名为:绿色")可在应用程序的其他部分中使用，但我也无法使用它来更改文本的颜色.我分配的颜色类型错误吗?情节提要中的值是否只是覆盖了此内容?如果是这样，我该如何阻止这种情况的发生?将其更改为= .red也不起作用.

UIColor(named: "Green") works in other parts of the app, but I can't change the colour of the text with it either. Am I assigning the wrong type of color? Are the values from the storyboard just overwriting this? If so, how could I stop that from happening? Changing it to = .red doesn't work either.

代码如下:

func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {


    let cell = tableView.dequeueReusableCell(withIdentifier: "ChapterCell") as! ChapterCell
    smallLabel(cell.chapterLabel, 18)
    cell.keepSubviewBackground = true

    if chapters[indexPath.row].completed == true {
        cell.chapterNumber.isHidden = true
        cell.chapterTick.isHidden = false
        cell.chapterLabel?.text = chapters[indexPath.row].generateTitle()
        cell.chapterLabel?.textColor = UIColor(named: "Green")
        cell.chapterNumberContainer.backgroundColor = UIColor(named: "Green")
    } else {
        cell.chapterLabel?.text = chapters[indexPath.row].generateTitle()
        cell.chapterNumber?.text = "#\(indexPath.row + 1)"
        cell.chapterTick.isHidden = true
        cell.chapterNumber.isHidden = false
        cell.chapterNumberContainer.backgroundColor = UIColor(named: "Eggshell")
    }

    if chapters[indexPath.row].locked == true {
        cell.chapterLabel?.alpha = 0.3
        cell.chapterNumberContainer?.alpha = 0.3
    } else {
        cell.chapterLabel?.alpha = 1
        cell.chapterNumberContainer?.alpha = 1
    }

    let cellBGView = UIView()
    cellBGView.backgroundColor = UIColor(red: 1.00, green: 1.00, blue: 1.00, alpha: 0.1)
    cell.selectedBackgroundView = cellBGView

    return cell
}
