    NSHTTPCookie *cookie; 
    NSHTTPCookieStorage *storage = [NSHTTPCookieStorage sharedHTTPCookieStorage]; 
    for (cookie in [storage cookies]) 
    { 
     NSString* domainName = [cookie domain]; 
     NSRange domainRange = [domainName rangeOfString:@"facebook"]; 
     if(domainRange.length > 0) 
     { 
      [storage deleteCookie:cookie]; 
     } 
    } 
    //////NSLog(@"facebook did logout");
