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 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。
我的应用就是基于这个，因为我在切换图片的时候想要这个效果。基本上，产生效果的观点是FlipView继承形式GenericAnimationView继承形式UIView。还有显示 1 个动画周期所需的AnimationFrame继承。NSObject最后，AnimationDelegate继承NSObject自转换操作的句柄回调。
这是我的AnimationViewController

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

我在其他帖子中看到他们谈到了 autoSized 面具，但我做不到......
有什么想法或建议吗？谢谢！
