hogyan lehet videofájlt lejátszani az ipad alkalmazás dokumentummappájából

Ehelyett

NSString *videopath = [[[NSString alloc] initWithString:[NSString stringWithFormat:@"%@/%@.mov",documentsDirectory,theDate]] autorelease];

kipróbálhatja .mov kiterjesztése nélkül. Mert ebben a sorban megmondja a kiterjesztést.

NSString *path = [[NSBundle mainBundle] pathForResource:videopath ofType:@"mov" inDirectory:nil];

Megjegyzés: Ebben a sorban

player = [[MPMoviePlayerViewController alloc] initWithContentURL:movieURL];

Ha a lejátszó megőrizte a tulajdonát, az memóriaszivárgást okoz.

először is hozzá kell adnia a mediaplayer keretrendszert a projekthez, majd hozzá kell adnia az import utasítást

#import <MediaPlayer/MediaPlayer.h>

majd kövesse az alábbi kódot

        MPMoviePlayerViewController *playerVC = [[MPMoviePlayerViewController alloc] initWithContentURL:[NSURL URLWithString:aVideoUrl]];



        // Register this class as an observer instead
    [[NSNotificationCenter defaultCenter] addObserver:self
                                             selector:@selector(movieFinishedCallback:)
                                                 name:MPMoviePlayerPlaybackDidFinishNotification
                                               object:playerVC.moviePlayer];


        // Set the modal transition style of your choice
        //playerVC.modalTransitionStyle = UIModalTransitionStyleFlipHorizontal;

        [self presentMoviePlayerViewControllerAnimated:playerVC];
        [playerVC.moviePlayer prepareToPlay];
        [playerVC.moviePlayer play];
        [playerVC.moviePlayer setControlStyle:MPMovieControlStyleFullscreen];



- (void)movieFinishedCallback:(NSNotification*)aNotification
{
    // Obtain the reason why the movie playback finished
    NSNumber *finishReason = [[aNotification userInfo] objectForKey:MPMoviePlayerPlaybackDidFinishReasonUserInfoKey];

    // Dismiss the view controller ONLY when the reason is not "playback ended"
    if ([finishReason intValue] != MPMovieFinishReasonPlaybackEnded)
    {
        MPMoviePlayerController *moviePlayer = [aNotification object];

        // Remove this class from the observers
        [[NSNotificationCenter defaultCenter] removeObserver:self
                                                        name:MPMoviePlayerPlaybackDidFinishNotification
                                                      object:moviePlayer];

        // Dismiss the view controller
        [self dismissModalViewControllerAnimated:YES];
    }
}
