ios - 将 UIRefreshControl 替换为 UIImageView

Question

我的 UITableView 中有一个 UIRefreshControl。我想用我自己的替换系统的刷新图标。我试过像这样向 refreshControl 添加一个 subview ......

    let refreshImage = UIImageView()
    refreshImage.image = UIImage(named: "RefreshIcon")
    refreshControl.insertSubview(refreshImage, at: 0)
    tableview.addSubview(refreshControl)

但这并没有奏效。有人有什么想法吗？非常感谢!

请试试这段代码:

 let refreshImage = UIImageView()
    refreshImage.image = UIImage(named: "RefreshIcon")
    refreshControl.backgroundColor = UIColor.clear
    refreshControl.tintColor = UIColor.clear
    refreshControl.addSubview(refreshImage)
    tableview.addSubview(refreshControl)

然后将它居中到顶部，你可以使用这个:

    refreshImage.frame = refreshControl.bounds.offsetBy(dx: self.view.frame.size.width / 2 - 20 // half the width of the refreshImage, dy: 10)
    refreshImage.frame.size.width = 40 // Whatever width you want
    refreshImage.frame.size.height = 40 // Whatever height you want
