以下は、mpmoviecontrollerを設定するための私のコードです。私はビデオの音を聞くことができますが、私はビデオの写真を見ることができません。私はインターネットで検索しましたが、自分のコードでエラーが見つかりませんでした。誰かがこのジレンマから抜け出すのを助けることができますか?iPadアプリケーションでmpmovieviewcontrollerが動作しませんか?
- (IBAction)playClicked:(id)sender {
NSString *path=[[NSBundle mainBundle] bundlePath];
path=[path stringByAppendingPathComponent:@"movies.bundle"];
path=[path stringByAppendingPathComponent:@"mean.mp4"];
NSURL *url=[NSURL fileURLWithPath:path];
NSFileManager *filemanager=[NSFileManager defaultManager];
if([filemanager fileExistsAtPath:path]){
NSLog(@"File exists at %@! You should be able to see the movie!:)",path);
MPMoviePlayerController *player=[[MPMoviePlayerController alloc] initWithContentURL:url];
if(player){
player.scalingMode = MPMovieScalingModeNone;
player.controlStyle=MPMovieControlStyleFullscreen;
player.movieSourceType=MPMovieSourceTypeFile;
[player.view setFrame:CGRectMake(0, navigationBar.bounds.size.height, self.view.bounds.size.width, self.view.bounds.size.height-navigationBar.bounds.size.height)];
[self.view addSubview:player.view];
[player prepareToPlay];
NSLog(@"Ready to play for %@!",player.duration);
[player play];
NSLog(@"Played!");
}
}else{
NSLog(@"File does not exist!:(");
}
}
ランタイムエラー(:)〜パスとURLが正しいことに注意してください):以下のコードを追加することはやるだろうと思われ
