UITableView Push to URL help - uitableview

Question

I am trying to push to a new view and send a url to the webview in that view but it's not getting the url request. storyLink is declared earlier on, but even if I try to request http://www.google.com it doesn't even work either, so I know the problem is it's not accepting the url for some reason.
DetailViewController *newviewController=[[[DetailViewController alloc] initWithNibName:#"DetailViewController" bundle:nil]autorelease];
NSURLRequest *request = [NSURLRequest requestWithURL:[NSURL URLWithString:storyLink]];
[newviewController.rssview loadRequest:request];
[self.navigationController pushViewController:newviewController animated:YES];

Better you declare a property in next view for NSURL and set the value from the parent view.
For example, set following code in your DetailViewController.h file
#interface DetailViewController : UIViewController
{
NSURL *request;
}
#property (nonatomic, assign) NSURL *request;
In your DetailViewController.m file...
#synthesize request;
And modify your current code as below...
DetailViewController *newviewController=[[[DetailViewController alloc] initWithNibName:#"DetailViewController" bundle:nil]autorelease];
NSURLRequest *request = [NSURLRequest requestWithURL:[NSURL URLWithString:storyLink]];
newviewController.request = request;
//[newviewController.rssview loadRequest:request];
[self.navigationController pushViewController:newviewController animated:YES];
In reference to your code...:
Following are some missing things that you have to modify in your code and it will start working fine.
Set delegate for UIWebview control.
self.rssview.delegate = self;
[self.rssview loadRequest:self.request];
In your DetailViewController.h, modify following lines.
#interface DetailViewController : UIViewController <UIWebViewDelegate>
{
IBOutlet UIWebView *rssview;
NSURLRequest *request;
}
#property(nonatomic, retain, readonly)UIWebView *rssview;
#property (nonatomic, assign) NSURLRequest *request;
#end
In DetailViewController.m add delegate method of UIWebview as given below...
- (BOOL)webView:(UIWebView *)myWebView shouldStartLoadWithRequest:(NSURLRequest *)request navigationType:(UIWebViewNavigationType)navigationType
{
return YES;
}
Replace following code in
- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
{
int storyIndex = [indexPath indexAtPosition: [indexPath length] - 1];
NSString * storyLink = [[stories objectAtIndex: storyIndex] objectForKey: #"link"];
// clean up the link - get rid of spaces, returns, and tabs...
storyLink = [storyLink stringByReplacingOccurrencesOfString:#" " withString:#""];
storyLink = [storyLink stringByReplacingOccurrencesOfString:#"\n" withString:#""];
storyLink = [storyLink stringByReplacingOccurrencesOfString:#" " withString:#""];
storyLink = [storyLink stringByAddingPercentEscapesUsingEncoding: NSStringEncodingConversionAllowLossy];
NSLog(#"link: %#", storyLink);
if(indexPath.row==0)
{
DetailViewController *newviewController=[[[DetailViewController alloc] initWithNibName:#"DetailViewController" bundle:nil]autorelease];
NSURLRequest *request = [NSURLRequest requestWithURL:[NSURL URLWithString:storyLink]];
//[newviewController.rssview loadRequest:request];
newviewController.request = request;
[self.navigationController pushViewController:newviewController animated:YES];
}
else
{
DetailViewController *newviewController=[[[DetailViewController alloc] initWithNibName:#"DetailViewController" bundle:nil]autorelease];
NSURLRequest *request = [NSURLRequest requestWithURL:[NSURL URLWithString:storyLink]];
//[newviewController.rssview loadRequest:request];
newviewController.request = request;
[self.navigationController pushViewController:newviewController animated:YES];
}
}
