Objective c 模拟器没有显示iPhone5的真实尺寸？

我正在xcode上尝试在模拟器上运行我们的应用程序，并检查屏幕高度。 我正在使用cocos2d，但我也尝试过苹果的方法

     NSLog(@"HEIGT:%f",[UIScreen mainScreen].bounds.size.height);

      //and also :
     winSize = [[CCDirector sharedDirector] winSize];
     NSLog(@"HEIGT:%f",winSize.Height);

在iPhone5的4英寸模拟版上，这两款手机的高度都达到了480。

为什么呢？我怎么知道这是不是真的iPhone5？

几天前，我遇到了同样的问题，解决方案是

为视网膜（4英寸）设置合适大小的启动图像

在您的项目中，拍摄一张尺寸为640*1136的图像，并添加到launch图像的视网膜图像中，您将获得实际尺寸。您也可以签入打印日志

这对我来说很好。

您添加了iphone 5 splash吗？-违约-568h@2x.png？查看这篇帖子：谢谢，这很有效。但如果我不想在加载时添加默认图像呢？如果您不能添加默认图像，则加载时会出现几秒钟的黑屏。
