MPMoviePlayerController 视图未调整大小

Question

我正在使用 MPMoviePlayerController，它将其 UIView 渲染到横向上的正确尺寸，但当旋转到纵向时，它根本不调整大小。我认为它的父 UIView 是不调整大小的。我该如何设置？

我按照 @Alex Reynolds 在 UIView autoresizingmask not work for me 中提到的说明进行操作。这表明视图在旋转时确实会调整大小。我仍然有一个问题，当加载容纳播放器的 UIViewController 的 UIView 时，如果设备的方向是横向的，它们会渲染到正确的框架，但如果设备在加载时处于纵向，则不会调整其大小。根据 @Alex Reynolds 的回答，我所要做的就是旋转设备一次，之后它将开始正确调整大小。

第一次无法调整大小仍然很糟糕。以前有人发生过这种情况吗？如果是这样，我们将不胜感激任何意见。

Answer 1

您是否正确设置了 MPMoviePlayerController 的 view 的 autoresizingMask ？其超级视图的 autoresizesSubviews 属性是否设置为 YES？ （同样，这个超级视图在旋转时也会调整大小吗？我喜欢在测试期间为我的视图设置彩色背景颜色，以验证它们在自动旋转时是否正确调整大小。）

如果在检查这些属性后仍然无法正常工作，您可以随时设置影片手动更改玩家视图的 frame 属性。超级视图的 layoutSubviews 方法通常是执行此操作的最佳位置，但如果它不是您手动子类化的视图，您也可以在视图控制器中执行此操作。
