Question

我在表视图部分标题中添加了一个按钮，该按钮当前仅在手机处于黑暗模式时显示，我不知道可能是什么问题。标头中的所有其他元素均以亮和暗模式显示。

headerHeight是静态200像素

override func tableView(_ tableView: UITableView, viewForHeaderInSection section: Int) -> UIView? {

    let view = UIView(frame: CGRect(x: 0, y: 0, width: tableView.frame.width, height: headerHeight))
    
    let imageButton = UIButton(frame: CGRect(x: view.frame.width / 2 - 50, y: 10, width: 100, height: 100))
    imageButton.setImage(UIImage(systemName: "person.crop.circle"), for: .normal)
    view.addSubview(imageButton)
    
    let nameButton = UIButton(frame: CGRect(x: 0, y: 110, width: tableView.frame.width, height: 40))
    nameButton.tintColor = .label
    nameButton.titleLabel?.textColor = .label
    nameButton.setTitle("Set Name", for: .normal)
    nameButton.titleLabel?.textAlignment = .center
    view.addSubview(nameButton)
    
    let accountsLabel = UILabel(frame: CGRect(x: 10, y: 175, width: 80, height: 20))
    accountsLabel.text = "Accounts"
    accountsLabel.font = UIFont(name: "Helvetica Neue", size: 15)
    view.addSubview(accountsLabel)
    
    return view
}

Answer 1

问题是这一行：

nameButton.titleLabel?.textColor = .label

这不是您设置按钮标题颜色的方式。更改为：

nameButton.setTitleColor(.label, for: .normal)

快速按钮仅在黑暗模式下显示
