Objective c 使用MPMoviePlayerController在ipad上安装1024x768

在花了一整天的时间研究为什么1024x768视频不能在iPad3上运行，以及大量的论坛搜索之后。我找不到任何合理的办法来解决这个问题。似乎很多人都有同样的情况，只显示一个黑屏

解决方案是按照1024x 748的要求渲染视频。原因是iPad顶部显示的状态栏是20px

我希望这能解决很多用户在这种情况下遇到的问题

我目前有一个视频通过MPMoviePlayerController嵌入到我的视图中。此视频处于恒定循环（动画菜单）中。然后，我在视频顶部有三个不可见的按钮，这些按钮被调用。我目前只有一个在工作，另外两个只是显示警报

目前我遇到的问题是，当点击按钮时，我希望播放另一个视频。这是完美的工作，但我希望第一个视频先播放到最后，再播放下一个视频，原因是，我也需要它是无缝的，而不是明显的从一个视频到另一个视频

关于这方面的任何反馈都非常好……

您是否尝试注册播放通知，特别是

MPMoviePlayerPlaybackDidFinishNotification

，很吸引人？如果在按下按钮时注册通知：

[[NSNotificationCenter defaultCenter] 
  addObserver:self 
  selector:@selector(introMovieFinished:) 
  name:MPMoviePlayerPlaybackDidFinishNotification 
  object:self.playerViewController];

然后在该函数中：

- (void)introMovieFinished:(NSNotification*)note {
  [[NSNotificationCenter defaultCenter] 
    removeObserver:self 
    name:MPMoviePlayerPlaybackDidFinishNotification
    object:self.playerViewController];
  // Do stuff.
}

---

您取消注册对通知的兴趣，然后开始播放下一部电影。因为您只在按下按钮时才注册兴趣，所以在电影结束之前，您不应该收到函数调用。
