Problem pushing URL's to in-app iPhone web browser

Question

Hi,

I have an RSS parser, which downloads a link to each item from an RSS feed. How do I make it so that when a user selects a row in the UITable, it opens my web view (made following this tutorial http://dblog.com.au/iphone-development/iphone-sdk-tutorial-build-your-very-own-web-browser/) with the URL of the item (which can be gathered by news.link)

Thanks.

DidSelectRow code:

webView = [incidents objectAtIndex:indexPath.row];
    NSURLRequest *request = [NSURLRequest requestWithURL: news.link];
    [webView loadRequest:request];
    [self.navigationController pushViewController:webView animated:YES];
    [tableView deselectRowAtIndexPath:indexPath animated:YES]
    [webView release];

Answer 1

You need to implement tableView:didSelectRowAtIndexPath: in the view controller that controls your UITableView.

- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
{
    NSURL* url = ... determine the URL to show ... ;

    ... load url in your Web view ... ;

    [tableView deselectRowAtIndexPath:indexPath animated:YES]; // Conform to Apple human-interface guidelines (Table View Programming Guide for iPhone OS)
}

Answer 2

What is webView in your code sample?
Which class is it?
UIViewController or UIWebView?

There is a line where you are using it as view controller and there is a line where you try to use it as a web view.

I bet it's a view controller, because you write that you have a warning on loadRequest line...

Anyhow, your view controller that has the web view should have some method that will receive a URL request and will load it to the web view:

// In webViewController.h:
- (void)loadWebViewWithRequest:(NSURLRequest *)request;

// In webViewController.m:
- (void)loadWebViewWithRequest:(NSURLRequest *)request {
    [webView loadRequest:request];
}

This is the method that you will have to use in your didSelectRow method instead of the loadRequest...
