如何在UIWebview中删除PDF的页码

Question

我目前正在使用以下代码

在UIWebview中嵌入PDF

override func viewDidLoad() {
    super.viewDidLoad()
    let lesson2_2 = "lesson2_2"
    if let url = Bundle.main.url(forResource: lesson2_2, withExtension: "pdf") {
        let urlRequest = URLRequest(url: url)
        webview.loadRequest(urlRequest as URLRequest)
        webview.scalesPageToFit = true
        webview.isOpaque = false
    }
}

PDF显示正常但在左上角的框中显示页码。有什么方法可以删除这个号码并将其隐藏起来吗？

哟可以尝试下面的代码，将隐藏左上角的页码视图：

 for subView: UIView in webView.subviews() {
        if (subView is UIScrollView) {
            for shadowView: UIView in subView.subviews() {
                if (shadowView is UIImageView) {
                    shadowView.isHidden = true
                }
            }
        }
    }
