如何打开一个UIWebView到另一个UIWebView的链接？

Question

I'm building an iOS app.
I have HTML content in a UIWebView with hyperlinks, and I'm unable to open a link to another UIWebView .
I used UIWebView as a subview of ViewController . Here is the code:

- (BOOL)webView:(UIWebView *)webView shouldStartLoadWithRequest:(NSURLRequest *)request navigationType:(UIWebViewNavigationType)navigationType
{
    switch (navigationType) {
        case UIWebViewNavigationTypeLinkClicked: { //this is when a user tap is detected
            //write the handling code here.
            isWebViewLoaded = false; //set this to false only if you open another view  controller.
            return NO; //prevent tapped URL from loading inside the UIWebView.
        }

        // some other typical parameters within a UIWebView. Use what is needed
        case UIWebViewNavigationTypeFormResubmitted: return YES;
        case UIWebViewNavigationTypeReload: return YES;

        //for all other cases, including UIWebViewNavigationTypeOther called when UIWebView is loading for the first time
        default: {
            if (!isWebViewLoaded) { 
                isWebViewLoaded = true; 
                return YES; 
            }
            else 
                return NO;
        } 
    }
}

You only need to segue to a new controller with a web view, and pass the request to it. So something like this in your first case,

 case UIWebViewNavigationTypeLinkClicked: { //this is when a user tap is detected
            [self performSegueWithIdentifier:@"Next" sender:request];
            isWebViewLoaded = false; //set this to false only if you open another view  controller.
            return NO; //prevent tapped URL from loading inside the UIWebView.
        }

Notice that the sender argument in performSegueWithIdentifier:sender: is the request returned by the delegate method. Pass this request to a property in the view controller you're segueing to,

-(void)prepareForSegue:(UIStoryboardSegue *)segue sender:(NSURLRequest *)sender {
    NextViewController *next = segue.destinationViewController;
    next.request = sender;
}

Finally, use that request to load the web view in NextViewController.
