    NSURL *url = [NSURL URLWithString:@"http://tinyurl.com/a3cx"]; 
    [self loadTinyURL:url]; 
} 
return self;

}

- (void)loadTinyURL:(NSURL *)url 
{ 
NSURLRequest *request = [NSURLRequest requestWithURL:url]; 
NSURLConnection *connection = [[NSURLConnection alloc] initWithRequest:request 
                   delegate:self]; 
if (!connection) 
    NSLog(@"could not connect with: %@", url); 
else { 
    NSLog(@"this works"); 
} 

} 


    - (NSURLRequest *)connection:(NSURLConnection *)connection 
     willSendRequest:(NSURLRequest *)request 
     redirectResponse:(NSURLResponse *)response 
    { 
NSHTTPURLResponse *httpResponse = (NSHTTPURLResponse *)response; 
int statusCode = [httpResponse statusCode]; 

// http statuscodes between 300 & 400 is a redirect ... 
if (response && statusCode >= 300 && statusCode < 400) 
    NSLog(@"redirecting to : %@", [request URL]); 

return request;

嗨，感謝您的鏈接，我試過這樣做，但它不工作，出於某種原因，我將通過問題更新與我的代碼.h和.m請幫我在這 – 2011-04-20 03:45:44

你是否繼承了NSURLConnection的委託方法，你的問題是什麼，你只給出了代碼..然後你在方法中加入了斷點來檢查它是否調用 – 2011-04-20 03:53:25
