Wkwebview没有加载新的请求网址

Question

我必须重新加载新的请求网址，但如果我尝试这样做，它会显示以前的网址。我还尝试在加载新请求之前加载空白。但它也不会起作用。

NSString * urlStr = [NSString stringWithFormat：@＆＃34; https://www.google.com＆＃34;];

webView_ = [[WKWebView alloc] initWithFrame:CGRectMake(0, 0, self.containerView.frame.size.width, self.containerView.frame.size.height) configuration:configuration];

webView_.autoresizingMask = UIViewAutoresizingFlexibleTopMargin| UIViewAutoresizingFlexibleLeftMargin | UIViewAutoresizingFlexibleRightMargin | UIViewAutoresizingFlexibleBottomMargin | UIViewAutoresizingFlexibleWidth | UIViewAutoresizingFlexibleHeight;

webView_.opaque = false;

webView_.navigationDelegate = self;
webView_.UIDelegate = self;

[webView_ loadRequest:nsrequest];

[self.containerView addSubview:webView_];

// [configuration.userContentController addScriptMessageHandler：self name：@＆＃34; interOp＆＃34;];
