不太理想，但以3.1为目标似乎可以解决问题.

Not ideal, but it seems targeting 3.1 solves the problem.

一种解决方法是，在调用play之前，将MPMoviePlayerController属性scalingMode设置为默认MPMovieScalingModeAspectFit以外的其他值(例如，MPMovieScalingModeNone并确保您的视频尺寸正确)，然后挂接事件.电影开始播放后，它似乎被叫(不止一次！).当然，如果用户手动更改缩放模式，也会调用它，因此为此编写代码.脏了，但可以帮您吗?

A workaround maybe to set the MPMoviePlayerController property scalingMode to something other than the default MPMovieScalingModeAspectFit ( e.g. MPMovieScalingModeNone and make sure your video is correct size) before calling play and then hook the MPMoviePlayerScalingModeDidChangeNotification event instead. it seems to get called (more than once!) as soon as the movie starts playing. Of course it will also be called if the user changes the scaling mode manually, so code for this. It's dirty but may help you?
