可可WebKit / WebView委托进行位置更改？ （用户点击的链接，JavaScript操作等） [英] Cocoa WebKit/WebView delegate for location change? (User clicked link, javascript action, etc)

问题描述

我已将WebView添加到Cocoa应用程序中，并且试图找出可以用来检测导航更改（用户单击链接或javascript触发更改位置等）的委托。

I have added a WebView to a Cocoa application and I'm trying to figure out which delegate I can use to detect when navigation changes (user clicks a link, or javascript fires to change the location, etc).

WebView类引用包含四个委托（WebFrameLoadDelegate协议参考，WebPolicyDelegate协议参考，WebResourceLoadDelegate协议参考和WebUIDelegate协议参考），我已经仔细研究了每个代理，但似乎找不到如何检测到这一点。我是否遗漏了一些显而易见的东西？或者没有办法得到这个东西？

The WebView class reference contains four delegates (WebFrameLoadDelegate Protocol Reference, WebPolicyDelegate Protocol Reference, WebResourceLoadDelegate Protocol Reference and WebUIDelegate Protocol Reference) and I have looked at each of these, but I cannot seem to find how to detect this. Am I missing something blatantly obvious or is there no way to get this?

tldr-试图弄清楚如何设置一个委托来在WebView出现时获取事件。更改网址。 （特别是我需要知道新的URL是什么。）

推荐答案

使用WebKit（例如MacOS X）可能是最好的选择跟踪请求位于 webView：identifierForInitialRequest：fromDataSource：中，尽管 webView：resource：willSendRequest：redirectResponse：fromDataSource：是也很好，并且具有允许您修改请求的优点。

Using WebKit (i.e. MacOS X) then probably the best place to track requests is in webView:identifierForInitialRequest:fromDataSource:, although webView:resource:willSendRequest:redirectResponse:fromDataSource: is also good, and has the advantage of allowing you to modify the request.

与iOS一样，您可以使用 [请求URL] 。

As with iOS, you can use [request URL].

通过 [webView setResourceLoadDelegate：self]; 进行设置。

资源负载委托（如我认为，上述方法比政策委托方法提供了更好的选项来处理请求。

The resource load delegate (as above) gives better options to handle the request, in my opinion, than the policy delegate methods.
