我的子视图在旋转后未自动调整

Question

我试图在iPad上制作一个简单的应用程序。目前，我只能在自定义视图中显示全屏图片。我的问题是，当iPad旋转时，我的视图不会自动调整...旋转完美，但是图像的大小仍然相同。

我的应用程序基于this，因为我在切换图片时需要此效果。基本上，产生效果的视图是FlipView，其继承形式GenericAnimationView，其形式为UIView。还有AnimationFrame从NSObject继承，需要显示1个动画循环。最后，有AnimationDelegate继承自NSObject，它处理来自变换操作的回调。

这里是我的AnimationViewController

    #import "FlipView.h" 
    #import "AnimationDelegate.h" 

    @implementation AnimationViewController 

    @synthesize flipView2;

    @synthesize panRegion; 
    @synthesize imageBluehound,imageDoggie,imagePointy,imagePurpGuy,imageRedDog,imageWoof;

    { 
     self = [super init]; 
     if (self) { 
      // Custom initialization 
      step = 0; 
     } 
     return self; 
    }

我，他们谈到了自动调整大小面具，但我不能让其他职位看到...

任何想法或建议？谢谢！

尝试修改视图/图像的支柱和字符串。点击图片后，转到实用检查器的大小选项卡。 “autosizing”旁边的示例将显示视图在框架更改时的样子。打开/关闭红色连接器和箭头，使图像在方向更改时以您想要的方式显示。
