私はビデオを再生するために次のコードを使用しています。実際にはとてもうまくいきます。 時々私は次のエラーを受け取ります - [AVFileValidator fpItemNotificationInfo:]:認識できないセレクターがインスタンス0x8114e50に送られました。私がこれについて調べたとき、私はメディアプレーヤーのプライベートセクションに達しました。私はそれが本当に何を意味するのか分からなかった。誰かが答えを知っていれば助けてください。- [AVFileValidator fpItemNotificationInfo:]:インスタンスに送信された認識できないセレクタ0x8114e50
-(void)playerPrepare
{
player.view.frame = CGRectMake(0.0f, 0.0f, 480.0f, 320.0f);
[self.view addSubview:player.view];
[player setControlStyle:MPMovieControlStyleNone];
[player play];
}
-(void)breadInPlate
{
// Do any additional setup after loading the view from its nib.
NSString *url = [[NSBundle mainBundle] pathForResource:@"10_Anim_iPhone"
ofType:@"mp4"];
NSURL *movieURL = [NSURL fileURLWithPath:url];
player = [[MPMoviePlayerController alloc]
initWithContentURL:movieURL];
[[NSNotificationCenter defaultCenter]
addObserver:self
selector:@selector(movieFinishedCallback:)
name:MPMoviePlayerPlaybackDidFinishNotification
object:player];
[player prepareToPlay];
[self performSelector:@selector(playerPrepare) withObject:nil afterDelay:0.5];
breadTimer = nil;
}
-(void)viewDidLoad
{
breadTimer = [NSTimer scheduledTimerWithTimeInterval:0.1 target:self selector:@selector(breadInPlate) userInfo:nil repeats:NO];
}
- (void) movieFinishedCallback:(NSNotification*) aNotification {
player = [aNotification object];
[[NSNotificationCenter defaultCenter]
removeObserver:self
name:MPMoviePlayerPlaybackDidFinishNotification
object:player];
[player.view removeFromSuperview];
[player release];
player = nil;
}
時折コードを実行しているうちに、次のエラーが表示されます。
