如何检查WkWebView是否在Objective-C中完成加载?

I want to load HTML pages using WkWebView and I want to show the page just after it's finished loading. As long as it's loading I would like to show an activity indicator on an empty View. I create two view a loadingView and a wkWebView. While the page is loading I add to VC as subview the loadingView and after I want to remove loadingView and add wkWebView. Here is my code:

我想使用WkWebView来加载HTML页面，我想在页面加载完成后显示出来。只要它正在加载，我希望在一个空视图上显示一个活动指示器。我创建了两个视图一个loadingView和一个wkWebView。在页面加载时，我将其添加到VC中作为loadingView的子视图，并在删除loadingView并添加wkWebView之后。这是我的代码:

    [self addSubview:_loadingView];
    _wkWebView = [[WKWebView alloc] initWithFrame:self.frame];
    _wkWebView.frame = CGRectMake(self.frame.origin.x, self.frame.origin.y, self.frame.size.width, self.frame.size.height);

    //Send a request to wkUrlconnection
    NSURL *wkUrl = [NSURL URLWithString:self.wkUrlString];
    NSURLRequest *wkRequest = [NSURLRequest requestWithURL:wkUrl];

    //Here I want to check if it's loaded and then remove loadingView and add wkWebView
    [_wkWebView loadRequest:wkRequest];
    [self.loadingView removeFromSuperview];
    [self addSubview:_wkWebView];

Can someone show me how to check while it's loading and if finish refresh the VC? Thank you for your answers.

有人能告诉我如何在加载时检查，如果完成刷新VC吗?谢谢你的回答。

I think the WKNavigationDelegate's webView:didFinishNavigation: delegate callback is what you're looking for.

我认为WKNavigationDelegate的webView:didFinishNavigation: delegate callback是你要找的。

Configure and present your activity indicator when you start to load and then stop and remove it from view when the callback is called.

在开始加载时配置并显示活动指示器，然后在调用回调时停止并将其从视图中删除。
