不能解僱模態視圖控制器與iOS5的

Question

我提出一個控制器來播放視頻：

[self presentModalViewController:movieController animated:YES]; 

，並添加一個觀察者時結束palying：

[[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(movieFinishedPlayback:) 
name:MPMoviePlayerPlaybackDidFinishNotification object:nil]; 
    } 

    -(void) movieFinishedPlayback:(NSNotification*)notification{ 
     NSLog(@"........movieFinishedPlayback....... \n "); 
     [self dismissModalViewControllerAnimated:YES]; 
     [[NSNotificationCenter defaultCenter] removeObserver:self name:MPMoviePlayerPlaybackDidFinishNotification object:nil]; 
    } 

這是我VideoDetailViewController：

#import "VideoDetailViewController.h" 
#import "PSStackedView.h" 
#import "YunMaoIpadAppDelegate.h" 

#define IpadAppDelegate ((YunMaoIpadAppDelegate *)[[UIApplication sharedApplication] delegate]) 
#define IphoneAppDelegate ((YunMaoIosAppDelegate *)[[UIApplication sharedApplication] delegate]) 

@interface VideoDetailViewController() 

@end 

@implementation VideoDetailViewController 

@synthesize video, moviePlayer, collectionsArray; 

-(id)initWithVideo:(Video *)theVideo 
{ 
    self = [super initWithNibName:@"VideoDetailViewController" bundle:nil]; 
    if (self) { 
     self.video = theVideo; 
    } 
    return self; 
} 
- (void)viewWillDisappear:(BOOL)animated 
{ 
    [moviePlayer pause]; 
    //[self.navigationController setNavigationBarHidden:false animated:animated]; 
    [super viewWillDisappear:animated]; 
} 

- (void)viewDidDisappear:(BOOL)animated; 
{ 
    [[UIApplication sharedApplication] setStatusBarHidden:YES withAnimation:UIStatusBarAnimationNone]; 

    [super viewDidDisappear:animated]; 
}

{ 
    [super viewWillAppear:animated]; 
    self.view.backgroundColor = [UIColor blackColor]; 
}

    //[DejalBezelActivityView removeViewAnimated:YES]; 
    [super viewDidAppear:animated]; 
}

    [super viewDidLoad]; 

    [self performSelector:@selector(displayActivityView) withObject:self.moviePlayer.view afterDelay:0.1]; 

    moviePlayer = [[MPMoviePlayerController alloc] initWithContentURL:[NSURL URLWithString:video.link]]; 
    [moviePlayer prepareToPlay]; 

    //[moviePlayer setShouldAutoplay:NO]; 
    moviePlayer.controlStyle = MPMovieControlStyleFullscreen; 
    moviePlayer.scalingMode = MPMovieScalingModeAspectFit; 

    if([moviePlayer respondsToSelector:@selector(useApplicationAudioSession)]) 
    { 
     if(UI_USER_INTERFACE_IDIOM() == UIUserInterfaceIdiomPhone) 
     { 
      NSLog(@"iPhone ios5.x"); 
      [moviePlayer.view setFrame: CGRectMake(0.0f, 0.0f, 480.0f, 320.0f)]; 
      //moviePlayer.view.transform = CGAffineTransformConcat(moviePlayer.view.transform, CGAffineTransformMakeRotation(M_PI_2)); 
     } 
     else{ 
      NSLog(@"iPad ios5.x"); 
      [moviePlayer.view setFrame: CGRectMake(0.0f, 0.0f, 1024.0f, 768.0f)]; 
      moviePlayer.view.transform = CGAffineTransformConcat(moviePlayer.view.transform, CGAffineTransformMakeRotation(M_PI_2)); 
      [moviePlayer.view setFrame:[IpadAppDelegate window].bounds]; 
     } 
    } 
    else 
    { 
     if(UI_USER_INTERFACE_IDIOM() == UIUserInterfaceIdiomPhone) 
     { 
      moviePlayer.view.transform = CGAffineTransformConcat(moviePlayer.view.transform, CGAffineTransformMakeRotation(M_PI_2)); 

      NSLog(@"iPhone ios6.x"); 
      CGSize result = [[UIScreen mainScreen] bounds].size; 
      if(result.height == 480) 
      {

      }

      { 
       //moviePlayer.controlStyle = MPMovieControlStyleDefault;

      } 
     }

      //[moviePlayer.view setFrame:[IpadAppDelegate window].bounds]; 
     } 
    } 

    [self.view addSubview:moviePlayer.view]; 
    [moviePlayer play];

Answer 1

這爲我工作。

[self dismissViewControllerAnimated:NO completion:^{ 
    [self.view removeFromSuperview]; 
}]; 

希望它有幫助！

Answer 2

駁回movieplayer做[moviePlayer stop];和蘇刪除movieplayer.view之前perview。之後嘗試解僱。這可能會解決這個問題。
