ios - 使用 MPMoviePlayerController 时的内存泄漏

Question

在我的项目中，我在不使用 Storyboard的情况下手动创建 View 。我尝试在点击图像时播放视频。它工作正常。但是每次当我点击图像时检查它显示内存泄漏，我已经搜索了很多并应用但没有用。 在我的 Appdelegate.h 文件中:

@property (strong, nonatomic) MPMoviePlayerController *theMoviePlayer;
@property (strong, nonatomic) UIImageView *image1;

在 .m 文件中:

-(void) startPage{
.....
_image1 = [[UIImageView alloc] initWithFrame:CGRectMake((self.window.frame.size.width/2)-25, 40, 50, 50)];
[_image1 setUserInteractionEnabled:YES];
_image1.image = [UIImage imageNamed:@"image_2.jpg"];
_tapImage1 = [[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(image1Tapped:)];
[_image1 addGestureRecognizer:_tapImage1];
.....}

在 imageTapped() 中，

-(void) image1Tapped:(UITapGestureRecognizer *)sender
{
  .....

 [_image1 removeFromSuperview];

 _theMoviePlayer = [[MPMoviePlayerController alloc] initWithContentURL:movieURL];


    [_theMoviePlayer setControlStyle:MPMovieControlStyleFullscreen];

    [_theMoviePlayer.view setFrame:CGRectMake(0,-55, self.window.frame.size.width, self.window.frame.size.height)];



    [_theMoviePlayer setScalingMode:MPMovieScalingModeAspectFill];

    UIWindow *backgroundWindow = [[UIApplication sharedApplication] keyWindow];

    [backgroundWindow addSubview:_theMoviePlayer.view];

    [_theMoviePlayer.view bringSubviewToFront:backgroundWindow];
[_theMoviePlayer play];
[[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(movieFinished:)
                                                 name:MPMoviePlayerPlaybackDidFinishNotification object:_theMoviePlayer];
...}

每次进入 imageTapped: 方法时我都会发生内存泄漏。任何帮助将不胜感激。

@property (strong, nonatomic) MPMoviePlayerController *theMoviePlayer;
@property (weak, nonatomic) UIImageView *image1;

另一个想法是你的 theMoviePlayer 没有被移除，试着让它的 View 透明，看看是否已经在新的后面工作了
