MPMoviePlayer 播放前的處理

這次為了處理有些影片無法播放

卻看不到player造成無法回到上一頁問題

之前因為使用MPMoviePlayerLoadStateDidChangeNotification來處理預載完畢後才加上player.view造成上面的情況

所以就改成先呈現player.View

但是必須要使用 MPMoviePlayerViewController 

因為 MPMoviePlayerController 在還沒可以播放前會是一片黑色

 MPMoviePlayerViewController *playerViewController = [[MPMoviePlayerViewController alloc] initWithContentURL:url];

    player=playerViewController.moviePlayer;

    

    //旋轉90度

   // player.view.transform = CGAffineTransformMakeRotation(1.5707964);

    

    //設定影片比例的縮放、重複、控制列等參數

    player.fullscreen=YES;

    player.scalingMode = MPMovieScalingModeAspectFit;

    player.repeatMode = MPMovieRepeatModeNone;

    player.controlStyle =MPMovieControlStyleFullscreen;

    //使用Observer製作完成播放時要執行的動作

    [[NSNotificationCenter defaultCenter] addObserver:self

                                             selector:@selector(moviePlayBackDidFinish:)

                                                 name:MPMoviePlayerPlaybackDidFinishNotification

                                               object:player];

  //  [[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(moviePreloadDidFinish:) name:MPMoviePlayerLoadStateDidChangeNotification object:nil];

    

    //自動縮放符合畫面比例

    // player.view.autoresizingMask = UIViewAutoresizingFlexibleWidth|UIViewAutoresizingFlexibleHeight;

    //將影片加至主畫面上

//因為要橫轉所以高和寬對調

    [player.view setFrame:CGRectMake(0, 0, self.view.bounds.size.height, self.view.bounds.size.width)];

   //  NSLog(@"%f,%f",self.view.bounds.size.height,self.view.bounds.size.width);

    [self.view addSubview:player.view];

    [player play];
