Currently, I am using a UIWebview to showcase my html page that contains picture links. Is there a way for me to set it up so that when the user clicks on a link, it opens a new view controller displaying the corresponding html image? Additionally, I would like to provide an option for users to return to the previous screen. Can you offer guidance on how to achieve this?
If your web view exclusively consists of image links, you can modify your current view controller to conform to the UIWebViewDelegate protocol like this:
- (BOOL)webView:(UIWebView *)webView
shouldStartLoadWithRequest:(NSURLRequest *)request
navigationType:(UIWebViewNavigationType)navigationType {
// In this section, you create a new view controller from your storyboard and pass the image URL to it. The new view controller should be able to display the image in an image view or any other desired way. Then, return NO to prevent the web view from loading the request, so that the user only sees your links.
SecondViewController* second = [self.storyboard instantiateViewControllerWithIdentifier:@"secondController"];
second.urlRequest = request;
[self.navigationController pushViewController:second animated:YES];
return NO;
}
Keep in mind that the code above assumes certain conditions:
You must have a property named urlRequest in your SecondViewController class.
Your navigation controller should include your FirstViewController.
You are utilizing storyboards and the ID of your SecondViewController is set as secondController.
