ローカルプロジェクトリソースからmpmovieplayercontrollerでビデオを再生しています。アプリコンソールを起動して、発生したエラーと、mpmovieplayercontrollerまたはmpmovieplayercontrollerの代替で適切な方法で修正および再生する方法を示しています。以下は、コンソール出力を取得しているがアプリがクラッシュしない場合のエラーを示しています。

ビデオを再生するための私のコードは次のとおりです。

#import "VideoPlayerControllerViewController.h"

@interface VideoPlayerControllerViewController ()

@end

@implementation VideoPlayerControllerViewController
@synthesize moviePlayer;

- (void)viewDidLoad
{
    [super viewDidLoad];
    [self playMovie];
    // Do any additional setup after loading the view, typically from a nib.

}

- (void)viewDidUnload
{
    [super viewDidUnload];
    // Release any retained subviews of the main view.
}

- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation
{
    return (interfaceOrientation != UIInterfaceOrientationPortraitUpsideDown);
}
-(void)moviePlayBackDidFinish:(NSNotification*)aNotification{
    NSLog(@"Play Back Finished!");
    [moviePlayer play];
}
-(void)playMovie
{
    NSURL *url = [NSURL fileURLWithPath:[[NSBundle mainBundle] 
                                         pathForResource:@"Menu_Free" ofType:@"mp4"]];
    moviePlayer =  [[MPMoviePlayerController alloc]
                    initWithContentURL:url];

    [[NSNotificationCenter defaultCenter] addObserver:self
                                             selector:@selector(moviePlayBackDidFinish:)
                                                 name:MPMoviePlayerPlaybackDidFinishNotification
                                               object:moviePlayer];

    moviePlayer.controlStyle = MPMovieControlStyleDefault;
    moviePlayer.shouldAutoplay = YES;
    moviePlayer.view.frame = self.view.bounds;
    moviePlayer.scalingMode= MPMovieScalingModeFill;
    moviePlayer.controlStyle =MPMovieControlStyleNone;
    [self.view addSubview:moviePlayer.view];
    [moviePlayer setFullscreen:YES animated:YES];
}

@end

前もって感謝します！

メソッドをこれに置き換えてください...

-(void)playMovie
{
    NSURL *url = [NSURL fileURLWithPath:[[NSBundle mainBundle] 
                                         pathForResource:@"Menu_Free.mp4" ofType:@""]];
    moviePlayer =  [[MPMoviePlayerController alloc]
                    initWithContentURL:url];

    [[NSNotificationCenter defaultCenter] addObserver:self
                                             selector:@selector(moviePlayBackDidFinish:)
                                                 name:MPMoviePlayerPlaybackDidFinishNotification
                                               object:moviePlayer];

    moviePlayer.controlStyle = MPMovieControlStyleDefault;
    moviePlayer.shouldAutoplay = YES;
    moviePlayer.view.frame = self.view.bounds;
    moviePlayer.scalingMode= MPMovieScalingModeFill;
    moviePlayer.controlStyle =MPMovieControlStyleNone;
    [self.view addSubview:moviePlayer.view];
    [moviePlayer setFullscreen:YES animated:YES];
}
