Question:

I have a URL.when i try to open it in browser, it will redirect to another URL & display the Content. I want that content But i don't get that redirected URL. So, I can't able to display data.

How can i do that programmatically??

<strong>e.g. URL which i have :</strong> <a href="http://www.windpowerengineering.com/?p=11020" rel="nofollow">http://www.windpowerengineering.com/?p=11020</a>

<strong>& the redirected URL is:</strong> <a href="http://www.windpowerengineering.com/design/mechanical/blades/bladeless-turbine-converts-wind-into-fluid-power/" rel="nofollow">http://www.windpowerengineering.com/design/mechanical/blades/bladeless-turbine-converts-wind-into-fluid-power/</a>

<strong>I want this redirected URL</strong>. How can i get this?

Answer1:

1) Specify that your class conforms to the UIWebViewDelegate protocol (and make sure your WebView's delegate outlet is connected to your view controller):

@interface YourWebsiteViewController : UIViewController <UIWebViewDelegate>

2) Add the following delegate method:

-(void)webViewDidStartLoad:(UIWebView *)webView { NSURL *url = [webView.request mainDocumentURL]; NSLog(@"The Redirected URL is: %@", url); }

Depending on what you're trying to do with this information, you might want to substitute #2 for this method (which will allow you the opportunity to prevent a page from loading):

- (BOOL)webView:(UIWebView *)webView shouldStartLoadWithRequest:(NSURLRequest *)request navigationType:(UIWebViewNavigationType)navigationType { NSURL *url = [request mainDocumentURL]; NSLog(@"The Redirected URL is: %@", url); // Return YES if you want to load the page, and NO if you don't. return NO; }

Answer2:

use javascript

document.referrer

Answer3:

Did you try this delegate method?

-(BOOL)webView:(UIWebView *)webView shouldStartLoadWithRequest:(NSURLRequest *)request navigationType:(UIWebViewNavigationType)navigationType{

It will be called whenever the webview loads a webpage.

You can get the URL from one of this method's parameters, request

NSURL *regURL=[request URL]; NSString *urlString=[regURL absoluteString];

Answer4:

That URL is part of the http header. This is what happening:

request 1: <a href="http://www.windpowerengineering.com/?p=11020" rel="nofollow">http://www.windpowerengineering.com/?p=11020</a>

response 1: page has moved go to <a href="http://www.windpowerengineering.com/design/mechanical/blades/bladeless-turbine-converts-wind-into-fluid-power/" rel="nofollow">http://www.windpowerengineering.com/design/mechanical/blades/bladeless-turbine-converts-wind-into-fluid-power/</a>

and then your browser will go:

request 2: <a href="http://www.windpowerengineering.com/design/mechanical/blades/bladeless-turbine-converts-wind-into-fluid-power/" rel="nofollow">http://www.windpowerengineering.com/design/mechanical/blades/bladeless-turbine-converts-wind-into-fluid-power/</a>

response 3: here is the html

If you look at the http headers from response 1 you will be able to extract the url from the Location header. In Objective C this is one way to do it:

NSURLResponse* response = // the response, from somewhere NSDictionary* headers = [(NSHTTPURLResponse *)response allHeaderFields]; NSString* redirection_url = [headers objectForKey:@"Location"];

In the above code you can access all of the response http headers from the headers dictionary.
