什么可能是错的？

- (BOOL)webView:(UIWebView *)webView shouldStartLoadWithRequest:(NSURLRequest *)request navigationType:(UIWebViewNavigationType)navigationType 
{ 
     NSLog(@"Button Clicked!"); 

return YES; 
} 

- (void)webViewDidStartLoad:(UIWebView *)webView 
{ 
orkutURLString = @""; 

[[UIApplication sharedApplication] setNetworkActivityIndicatorVisible:TRUE]; 
} 

- (void)webViewDidFinishLoad:(UIWebView *)webView 
{ 
NSURL *currentURL = orkutWebView.request.mainDocumentURL; 

NSLog(@"Relative URL: %@",[currentURL relativePath]); 

NSArray *urllistItems = [[currentURL relativePath] componentsSeparatedByString:@"/"]; 

if([urllistItems count]>1) 
{ 
    orkutURLString = [urllistItems objectAtIndex:1]; 
    orkutURLString = [orkutURLString lowercaseString]; 

    if([orkutURLString isEqualToString:@"share"]) 
    { 
     orkutWebView = nil; 
     [orkutWebView removeFromSuperview]; 
     [orkutView removeFromSuperview]; 
     NSString *message1 = NSLocalizedStringFromTableInBundle(@"Your status update was sent", @"Localizable", [NewfoxRadioAppDelegate GetLocalizebundle], @""); 
     UIAlertView *alertView = [[UIAlertView alloc]initWithTitle:@"Newfox Radio" message:message1 delegate:self cancelButtonTitle:@"OK" otherButtonTitles:nil]; 
     [alertView show]; 
     [alertView release]; 
    } 
} 

[[UIApplication sharedApplication] setNetworkActivityIndicatorVisible:FALSE]; 
} 

- (void)webView:(UIWebView *)webView didFailLoadWithError:(NSError *)error 
{ 
[[UIApplication sharedApplication] setNetworkActivityIndicatorVisible:FALSE]; 
}

你用过webview委托方法吗？ –

你是否在使用网页浏览器的指标？ – SJS

@HonestSuccess：不，我不使用UIWebView的指标 –

得到了解决办法。有一个NSZombie，其中我释放的对象，然后试图访问它。在使用仪器找出NSZombie之后得到了理想的结果。
