webView 跳过历史某个界面

授权界面一般授权成功后需要跳过之前授权的界面，第一种方式backList可以跳过授权界面

   NSArray<WKBackForwardListItem *> *backList = wkWebView.backForwardList.backItem;

    if(backList[_index]) {

        [wkWebViewgoToBackForwardListItem:backList[_index]];

    }

第二种方式通过调用web的replace修改历史界面url

- (void)call:(WKWebView*)webViewurl:(NSString*)url{

    if ([[NSThread currentThread] isMainThread])    {

        NSString *javascriptCommand = [NSString stringWithFormat:@"%@('%@');", @"window.location.replace", url];

        [webViewevaluateJavaScript:javascriptCommandcompletionHandler:nil];

    }

    else    {

        dispatch_sync(dispatch_get_main_queue(), ^{

            NSString *javascriptCommand = [NSString stringWithFormat:@"%@('%@');", @"window.location.replace", url];

            [webViewevaluateJavaScript:javascriptCommandcompletionHandler:nil];

        });

    }

}
