xcode - 在 4.2.1 版本之后在 Xcode 中播放视频

Question

好像在 Xcode 4.2.1 版之后我的视频代码不起作用？

目标C代码：

NSURL *url = [NSURL fileURLWithPath:
  [[NSBundle mainBundle] pathForResource:@"h" ofType:@"mp4"]];

MPMoviePlayerViewController *playercontroller = 
  [[MPMoviePlayerViewController alloc] initWithContentURL:url];

[self presentMoviePlayerViewControllerAnimated:playercontroller];

playercontroller.moviePlayer.movieSourceType = MPMovieSourceTypeFile;

[playercontroller.moviePlayer play];
// [playercontroller release];
playercontroller = nil;

Answer 1

尝试代替

[self presentMoviePlayerViewControllerAnimated:playercontroller];

[[self navigationController]presentMoviePlayerViewControllerAnimated:playercontroller];

如果您使用的是导航控制器。
