I'm using a RSS Reader and works fine when I tap the UITableViewCell to load the <link> either in a UIWebView or to open Safari on that link.
But I really want to learn how to load the Topic content into the application instead showing the entire site or jump to Safari
In the RSS feed per each <item> there is a <body> tag (and a <Description> that contains the same but encoded) that contains the topic content, like the image below shows:
So, instead of catching the <link> I'm assigning the <body>. Problem is that it does not work correctly :-(
for this example I only get the content until the first <br> nothing more.
- I'm using a
NSStringas I would use in C#, should I use any other object, is there a better object to use on such data? - Should I use an
UITextViewto load this information (as it has scroll already) or I should use aUIWebViewinstead?
Thank you.

[item setObject:currentTitle forKey:@"title"];

}
and to pass to my WebBrowser View I have:
- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath {
// Navigation logic
int storyIndex = [indexPath indexAtPosition: [indexPath length] - 1];
NSString * storyContent = [[stories objectAtIndex: storyIndex] objectForKey: @"body"];
// load web view
[self showWebPage:storyContent]; // <-- Here (storyContent variable) I only have the content until the first <br> :-(
