推荐答案

这是一个真正的hacky解决方案，可能无法长期运作，但可能会给你一个起点。重新排序控件是 UITableViewCellReorderControl ，但这是一个私有类，因此您无法直接访问它。但是，您可以查看子视图的层次结构并找到其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.

您可以通过继承 UITableViewCell 并覆盖其 setEditing：animated：方法如下：

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"];
                    }
                }
            }
        }
    }   
}

或在Swift中

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

    if (editing) {

        for view in subviews as [UIView] {
            if view.dynamicType.description().rangeOfString("Reorder") != nil {
                for subview in view.subviews as [UIImageView] {
                    if subview.isKindOfClass(UIImageView) {
                        subview.image = UIImage(named: "yourimage.png")
                    }
                }
            }
        }
    }
}

请注意......这可能不会很长术语解决方案，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.
