问题描述

我创建了一个带有时间戳的500 p标签的html字符串

i create a html string with 500 p tag with timestamp in it

我使用UIWebView和WKWebView loadHTMLString:baseURL:进行加载，而wkWebView的速度比UIWebVIew慢 50％.为什么?

i use UIWebView and WKWebView loadHTMLString:baseURL: to load it,and wkWebView is slower about 50% than UIWebVIew. why?

UIWebView:0.1681529879570007
WKWebView:0.3913570046424866

推荐答案

WKWebView可以更快地显示来自字符串的html.但是，默认情况下，有一个错误可使UIWebView更快，这是电话号码检测.

WKWebView is faster for displaying html from Strings. However, there is a bug that makes UIWebView faster by default, which is the phone number detection.

使用以下代码运行一个viewController，webView分别是一个UIWebView和WKWebView实例，并使其他所有东西保持相同，我发现WKWebView最多需要2秒钟加载，而UIWebView几乎立即加载.

Running a viewController with the following code, webView being respectively a UIWebView and WKWebView instance and keeping everything else identical I found WKWebView to take up to 2 seconds to load, while UIWebView loads almost instantly.

webView.loadHTMLString(HtmlStringInstance, baseURL: nil)

到目前为止，我并不是唯一一个找到这个的人:

I'm by far not the only one to find this:

• 当我使用wkwebview加载本地html时，我发现它的渲染速度比uiwebview慢
• UIWebView延迟加载本地内容
• 从字符串中缓慢加载UIWebView
• 延迟将HTML字符串加载到UIWebView中
• 为什么当使用UIWebView加载HTMLString时，UIWebView的工作如此缓慢? /a>

• when I use wkwebview to load local html,I find it renders slower than uiwebview
• UIWebView delay in loading local content
• Slow loading UIWebView from string
• Delay in loading a HTML string into a UIWebView
• Why UIWebView work so slowly when loadHTMLString with UIWebView?

但是，解决方案很简单:禁用WKWebView和poof的电话号码检测.你去那里.

However, the solution is easy: Disable phone number detection for WKWebView and poof. There you go.
