关于MpMoviePlayerViewController

Question

大家好晚会

我已经看过我必须播放视频，视频正在播放完美，但很少我视频没有出现在视图上，当时我在控制台中收到警告，如< / p>

警告：在正常情况下，_fillInQueueWithExtraSpace：ignoreExistingItems：不应重新输入。

有人可以帮我解决这个问题

谢谢大家

我在同一个视图中显示2个UIView，在一个视图中，当我开始绘制movieplayer时，在bottomProgressView中启动，在viewdtroller中的viewdtroller中，代码就像这样

        - (void)viewDidLoad
{
    [super viewDidLoad];
NSString *url = [[NSBundle mainBundle] pathForResource:@"progres" ofType:@"mp4"];
    timeCompletedCnlr = [[MPMoviePlayerController alloc] initWithContentURL:[NSURL fileURLWithPath:url]] ;
    [timeCompletedCnlr.view setFrame:CGRectMake(0,468, 600, 50)]; 
    [timeCompletedCnlr setControlStyle:MPMovieControlStyleNone];
    [bottomProgressView addSubview:timeCompletedCnlr.view];
}

当我触摸要绘制的视图时，将调用以下方法。

     - (void)removeGivenWord
{
    [bottomToolBar removeFromSuperview];
    [self.view addSubview:bottomProgressView];

    [timeCompletedCnlr play];
    [[NSNotificationCenter defaultCenter] addObserver:self 
                                             selector:@selector(helpVideoFinished:)
                                                 name:MPMoviePlayerPlaybackDidFinishNotification     
                                               object:timeCompletedCnlr];

    UIButton *doneBtn = [UIButton buttonWithType:UIButtonTypeCustom];
    doneBtn.frame = CGRectMake(601, 940, 167, 43);
    [doneBtn setBackgroundImage:[UIImage imageNamed:@"done.png"] forState:UIControlStateNormal];
    [doneBtn addTarget:self action:@selector(doneButtonClicked) forControlEvents:UIControlEventTouchUpInside];
    [self.view addSubview:doneBtn];

}

放置视频的视图也包含完成按钮..

    - (void)doneButtonClicked {       
[timeCompletedCnlr stop];       
[[NSNotificationCenter defaultCenter] addObserver:self 
                                         selector:@selector(helpVideoFinished:)
                                             name:MPMoviePlayerPlaybackDidFinishNotification  
                                           object:timeCompletedCnlr];      

}

     - (void) helpVideoFinished:(NSNotification*) aNotification {     
MPMoviePlayerController *player1 = [aNotification object];     
[[NSNotificationCenter defaultCenter]removeObserver:self 
                                               name:MPMoviePlayerPlaybackDidFinishNotification
                                             object:player1];     
[smoothLineView completed5Sec];     
NSLog(@"5sec called");     
NSError *error = [[aNotification userInfo] objectForKey:@"error"];     
if (error) {
    NSLog(@"Did finish with error: %@", error);
}

}

我的问题是视频有时出现，有时它不会出现，
