问题描述

在下图中，如何将视图右侧的按钮的颜色更改为白色?理想情况下，只希望某些单元格为白色而其他单元格为黑色这是我的代码:

In the image below, how do I change the color of the buttons on the right hand side of the view to white?edit: Ideally only want it to be white for certain cells and black for others Here's my code:

cell.backgroundColor = .appOrange
cell.contentLabel.textColor = .white
cell.numberLabel.textColor = .white
cell.tintColor = .white //this appears to do nothing, just something I tried

推荐答案

这适用于我使用iOS11和Swift 4的UITableViewController:

This works for me in my UITableViewController using iOS11 and Swift 4:

private var myReorderImage : UIImage? = nil;

override func tableView(_ tableView: UITableView, willDisplay cell: UITableViewCell, forRowAt indexPath: IndexPath) {
    for subViewA in cell.subviews {
        if (subViewA.classForCoder.description() == "UITableViewCellReorderControl") {
            for subViewB in subViewA.subviews {
                if (subViewB.isKind(of: UIImageView.classForCoder())) {
                    let imageView = subViewB as! UIImageView;
                    if (myReorderImage == nil) {
                        let myImage = imageView.image;
                        myReorderImage = myImage?.withRenderingMode(UIImageRenderingMode.alwaysTemplate);
                    }
                    imageView.image = myReorderImage;
                    imageView.tintColor = UIColor.red;
                    break;
                }
            }
            break;
        }
    }
}
