iOS UIWebView自适应实际内容高度

获取webview中scrovllview的contentsize进行设置

// MARK: - WKNavigationDelegate
func webView(_ webView: WKWebView, didFinish navigation: WKNavigation!) {
    
    let webViewHeight = webView.scrollView.contentSize.height
    var newFrame = webView.frame
    newFrame.size.height = webViewHeight
    webView.frame = newFrame
}
