MPMoviePlayerController.view未从superview中删除

Question

这是我的代码

- (void)viewDidLoad
{
...
 NSString *filepath   =   [[NSBundle mainBundle] pathForResource:@"movie" ofType:@"mov"];
NSURL    *fileURL    =   [NSURL fileURLWithPath:filepath];
_moviePlayerController = [[MPMoviePlayerController alloc] initWithContentURL:fileURL];
[self.view addSubview:_moviePlayerController.view];
_moviePlayerController.fullscreen = YES;
_moviePlayerController.scalingMode = MPMovieScalingModeAspectFit;
_moviePlayerController.controlStyle=MPMovieControlStyleDefault;
[_moviePlayerController play];

[[NSNotificationCenter defaultCenter] addObserver:self
                                             selector:@selector(movieIsOver:)
                                                 name:MPMoviePlayerPlaybackDidFinishNotification
                                               object:nil];
}

- (void)movieIsOver:(NSNotification *)notification
{
    NSLog(@"movie is over");
   [[NSNotificationCenter defaultCenter] removeObserver:self];
    [self.moviePlayerController.view removeFromSuperview];//moviePlayerController is MPMoviePlayerController
}

当电影播放结束时，我看不到“电影结束”日志，并且不删除moviePlayerController.view。我不知道为什么。

修改 MPMoviePlayerPlaybackDidFinishNotification运行良好。我看到“电影结束”日志。问题是moviePlayerController.view未被删除。

Answer 1

我找到了解决方案：添加

_moviePlayerController.fullscreen = NO;

从superview中删除视图之前

Answer 2

而不是将_moviePlayerController.view添加为子视图

[self.view addSubview:_moviePlayerController.view];

你可以像这样出现_moviePlayerController：

[self presentMoviePlayerViewControllerAnimated: _moviePlayerController];

并且在movieIsOver方法中你只需忽略

[self dismissMoviePlayerViewControllerAnimated];

我希望得到它的帮助
