reload 之后delegate问题

[Sima Shui]

当页面reload之后，不会再次响应didChangeToSection和willChangeToSection

以下是配置代码:

• (UIView *) viewAtTop {
  return self.tableView;
  }

• (NSUInteger ) numberOfSections {
  return 1;
  }

• (NSString *) titleOfSectionAt:(NSUInteger )index {
  return @"";
  }

• (UIView *) viewOfSectionAt:(NSUInteger ) index {
  UIWebView *webview = [[UIWebView alloc] initWithFrame:CGRectZero];
  webview.delegate = self;
  return webview;
  }

• (void) didChangeToSection:(NSUInteger) index view:(UIView *) view {
  if (index == 0) {
  NSString *urlString = [NSString stringWithFormat:@"%@%@?goodsId=%@", HOME_URL, GOODS_DETAIL_INFO_URL, self.goodsId];
  [(UIWebView *)view loadRequest:[NSURLRequest requestWithURL:[NSURL URLWithString:urlString]]];
  [(UIWebView *)view reload];
  }
  NSLog(@"did= %ld %@", index, view);
  }

• (void) willChangeToSection:(NSUInteger) index view:(UIView *) view {
  NSLog(@"will=%ld %@", index, view);
  }
