MpMovieplayerController tap gesture recognizer doesn't trigger when in fullscreen

问题

I´m trying to use UITapGestureRecognizer in order to handle the taps on my fullscreen video. If I omit [self.player setFullscreen:YES animated:NO]; it works, but then my video won't scale to fit the screen.

From my .m:

- (void)viewDidLoad
{
    [super viewDidLoad];

    NSString *videoPath = [[NSBundle mainBundle] pathForResource:@"test" ofType:@"mov"];
    player =  [[MPMoviePlayerController alloc] initWithContentURL:[NSURL fileURLWithPath:videoPath]];

    player.shouldAutoplay = NO;
    player.view.frame = self.view.bounds;
    player.scalingMode = MPMovieScalingModeAspectFit;
    player.controlStyle = MPMovieControlStyleNone;
    player.fullscreen = YES;
    self.player = player;
    [self.player prepareToPlay];

    UITapGestureRecognizer *tapGesture = [[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(handleTap:)];
    UIView *aView = [[UIView alloc] initWithFrame:player.view.bounds];
    [aView addGestureRecognizer:tapGesture];
    [self.player.view addSubview:aView];
}

- (IBAction)playMovie:(id)sender {
    //add the MPMoviePlayerViewController to this view (as subview)
    //Play movie
    [self.view addSubview:self.player.view];
    [self.player setFullscreen:YES animated:NO]; //commenting out this will make it work
    [self.player play];
}

- (void)handleTap:(UITapGestureRecognizer *)recognizer {
    NSLog(@"tap tap");
}

From my .h:

@property (retain, nonatomic) MPMoviePlayerController *player;
- (void)handleTap:(UITapGestureRecognizer *)recognizer;

回答1:

In my comment, I drafted how to get that covered when using proper fullscreen ([self.player setFullscreen:YES animated:NO];).

I would suggest that instead you simply resize the player view to cover the entire screen by setting its frame accordingly.

You initialising code would have to get rid of that player.fullscreen = YES;, but that I guess is obvious by now.

You can try this:

[[NSNotificationCenter defaultCenter] addObserver:self
                                         selector:@selector(willEnterFullScreen:)
                                             name:MPMoviePlayerWillEnterFullscreenNotification
                                           object:nil];

- (void)willEnterFullScreen:(NSNotification*)notification
{
    UITapGestureRecognizer *tapGesture = [[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(handleTap:)];
    UIView *aView = [[UIView alloc] initWithFrame:self.player.backgroundView.bounds];
    [aView addGestureRecognizer:tapGesture];
    [self.view.window addSubview:aView];
}

and then remove your subview when MPMoviePlayerWillExitFullscreenNotification is posted
