Swift - 如何更改accessoryType(disclosureIndicator)的颜色？

Question

我accessoryType对细胞有疑问.我正在使用带有disclosureIndicatoras 的单元格,accessoryType我想改变它的颜色,但我不能.有谁知道这是一个错误还是Apple迫使我使用灰色？其实我可以改变其他的颜色accessoryType.

我的代码看起来像这样:

let cell = tableView.dequeueReusableCell(withIdentifier: "identifier", for: indexPath) as! customCell
cell.tintColor = UIColor.red
cell.accessoryType = .disclosureIndicator

而我的箭仍然是灰色的.但如果我使用复选标记,accessoryType它会变成红色.

有没有办法解决这个问题,还是我必须使用彩色图像？

Answer 1

你可以做这样的事情

override func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
    let cell = tableView.dequeueReusableCell(withIdentifier: "Cell", for: indexPath)
    cell.tintColor = UIColor.white

    let image = UIImage(named: "Arrow.png")
    let checkmark  = UIImageView(frame:CGRect(x:0, y:0, width:(image?.size.width)!, height:(image?.size.height)!));
    checkmark.image = image
    cell.accessoryView = checkmark

    let object = objects[indexPath.row] as! NSDate
    cell.textLabel!.text = object.description
    return cell
}

使用SF符号

let image = UIImage(systemName: "chevron.right")
let accessory  = UIImageView(frame:CGRect(x:0, y:0, width:(image?.size.width)!, height:(image?.size.height)!))
accessory.image = image

// set the color here
accessory.tintColor = UIColor.white
cell.accessoryView = accessory

为 Swift 4.2 更新并附有图像：

    cell.accessoryType = .disclosureIndicator
    cell.tintColor = .black
    let image = UIImage(named:"disclosureArrow")?.withRenderingMode(.alwaysTemplate)
    if let width = image?.size.width, let height = image?.size.height {
        let disclosureImageView = UIImageView(frame: CGRect(x: 0, y: 0, width: width, height: height))
        disclosureImageView.image = image
        cell.accessoryView = disclosureImageView
    }
