我的子视图在旋转后没有自动调整大小

Question

我正在尝试在 iPad 上制作一个简单的应用程序。现在我只在自定义视图中显示全屏图片。我的问题是当 iPad 旋转时我的视图没有自动调整大小......旋转效果很好，但我的图像大小仍然相同。

我的应用是基于this，因为我在切换图片的时候想要这个效果。基本上，产生效果的视图是FlipView，它继承了GenericAnimationView 的形式，它继承了UIView 的形式。还有 AnimationFrame 继承自 NSObject ，这是显示 1 个动画周期所必需的。最后，AnimationDelegate 继承自 NSObject，它处理来自转换操作的回调。

这是我的AnimationViewController

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

    @implementation AnimationViewController

    @synthesize flipView2;
    @synthesize panRecognizer;
    @synthesize panRegion;
    @synthesize imageBluehound,imageDoggie,imagePointy,imagePurpGuy,imageRedDog,imageWoof;

            // Custom initialization

        }
        return self;
    }

        // Releases the view if it doesn't have a superview.

我在其他帖子中看到他们谈到了 autoSized 蒙版，但我做不到...

有什么想法或建议吗？谢谢！

尝试修改视图/图像的支柱和字符串。单击图像后，转到实用程序检查器的大小选项卡。 “自动调整大小”旁边的示例将显示视图在框架更改时的外观。打开/关闭红色连接器和箭头，以使图像在方向更改时看起来像您想要的那样。
