推荐答案
如果要获取WKWebView中html的内容高度以使其在UIScrollView中不可滚动，请继续阅读.
If you mean to get the content height of the html in WKWebView to make it non-scrollable inside UIScrollView, then read on.
您需要(通过委托)观察webView的内容高度.我正在为您提供这些步骤，因为您完全知道自己在做什么，并且快要到了.
You need to observe (via delegate) the content height of your webView. I'm giving you these steps, since you quite know what you're doing, and you're almost there.
摆脱网络视图高度限制的影响
@IBOutlet weak var constraint_WebViewHeight: NSLayoutConstraint!
订阅webView的代表
这会让您知道(您的控制器在您的webView加载完网站内容之后.
This will let you know (your controller when your webView has finished loading the contents of your site.
self.webView.navigationDelegate = self
符合协议
在WKNavigationDelegate的didFinish navigation方法中，然后调整webView高度约束的常数.如果需要，可以放一些动画:)
Inside the didFinish navigation method of WKNavigationDelegate, you then adjust the constant of your webView height constraint. Put some animation if you want to :)
extension ViewController: WKNavigationDelegate {
func webView(_ webView: WKWebView, didFinish navigation: WKNavigation!) {
DispatchQueue.main.asyncAfter(deadline: .now() + 0.1) {
self.constraint_WebViewHeight.constant = webView.scrollView.contentSize.height
}
}
}
最后，解决您的约束.
a.删除您的imageView底部约束. b.将底部约束添加到"scrollView"的保存"按钮中.
a. Remove your imageView bottom constraint. b. Add bottom constraint to your save button to the scrollView.
这将使您的scrollView可滚动.
This will make your scrollView scrollable.
Voila！这样就产生了结果.
Voila! This yields this result.
