推荐答案

这是一个非常棘手的解决方案，可能不会长期有效，但可能会给您一个起点.重新排序控件是一个UITableViewCellReorderControl，但它是一个私有类，所以你不能直接访问它.但是，您可以查看子视图的层次结构并找到它的 imageView.

This is a really hacky solution, and may not work long term, but may give you a starting point. The re-order control is a UITableViewCellReorderControl, but that's a private class, so you can't access it directly. However, you could just look through the hierarchy of subviews and find its imageView.

您可以通过子类化 UITableViewCell 并按如下方式覆盖其 setEditing:animated: 方法来实现:

You can do this by subclassing UITableViewCell and overriding its setEditing:animated: method as follows:

- (void) setEditing:(BOOL)editing animated:(BOOL)animated
{
    [super setEditing: editing animated: YES];

    if (editing) {

        for (UIView * view in self.subviews) {
            if ([NSStringFromClass([view class]) rangeOfString: @"Reorder"].location != NSNotFound) {
                for (UIView * subview in view.subviews) {
                    if ([subview isKindOfClass: [UIImageView class]]) {
                        ((UIImageView *)subview).image = [UIImage imageNamed: @"yourimage.png"];
                    }
                }
            }
        }
    }   
}

或者在 Swift 中

override func setEditing(_ editing: Bool, animated: Bool) {
    super.setEditing(editing, animated: animated)

    if editing {
        for view in subviews where view.description.contains("Reorder") {
            for case let subview as UIImageView in view.subviews {
                subview.image = UIImage(named: "yourimage.png")
            }
        }
    }
}

不过请注意...这可能不是一个长期的解决方案，因为 Apple 可以随时更改视图层次结构.

Be warned though... this may not be a long term solution, as Apple could change the view hierarchy at any time.
