iphone - Webview 适用于 iPhone，但不适用于 iPad

Question

下面的代码在 Iphone 上运行，我在 ipad 上加载 webview 时遇到问题，它遇到了 didFailwith 错误，(iPad 已连接)有任何帮助吗？

 - (void)viewDidAppear:(BOOL)animated
{
      NSURL *url;
      if ([[UIDevice currentDevice] userInterfaceIdiom] == UIUserInterfaceIdiomPad) {
          url = [NSURL URLWithString:@"http://www.google.com"];
      }else{
          url = [NSURL URLWithString:@"http://www.google.com"];
      }
      NSURLRequest *req = [NSURLRequest requestWithURL:url]; 
      [webSurfForecast loadRequest:req];
      [super viewDidAppear:YES];
  }

 -(void)webView:(UIWebView *)webView didFailLoadWithError:(NSError *)error {
     UIAlertView *alert = [[UIAlertView alloc] initWithTitle:@"Error" message:@"Can't connect. Please check your          internet Connection" delegate:self cancelButtonTitle:@"OK" otherButtonTitles:nil];
[alert show];
}

你可以这样检查..

  BOOL iPad = NO;
  #ifdef UI_USER_INTERFACE_IDIOM
  iPad = (UI_USER_INTERFACE_IDIOM() == UIUserInterfaceIdiomPad);
  #endif
  if (iPad) {
            // iPad specific code here
   } else {
            // iPhone/iPod specific code here
   }
