我正在尝试让 MPMovieplayerController 工作。我加载了一个视频,一切顺利,我什至看到了第一帧,但它会自动暂停,如果我按下播放,它会再次暂停。在模拟器中它工作得很好,但在 ipad 设备上它给出了问题。我什至可以通过视频寻找,我看到了我寻找的帧,但没有播放。这是控制台的一些输出:
2010-06-08 22:16:13.145 app[3089:207] Using two-stage rotation animation. To use the smoother single-stage animation, this application must remove two-stage method implementations.

顺便说一句,使用模拟器时我没有收到这些警告。
有谁知道如何解决这一问题 ?
