ios5 - 无法使用 ios5 关闭模态视图控制器

Question

我提出一个控制器来播放视频：

  [self presentModalViewController:movieController animated:YES];

并在完成播放时添加一个观察者：

    [[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];
    }

这是我的 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;
}

{
    [moviePlayer pause];
    //[self.navigationController setNavigationBarHidden:false animated:animated];
    [super viewWillDisappear:animated];

    self.view.backgroundColor = [UIColor blackColor];

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

    [moviePlayer prepareToPlay];

    //[moviePlayer setShouldAutoplay:NO];

        }
        else{

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

        {

Answer 1

这对我有用。

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

希望能帮助到你！

Answer 2

在关闭movieplayer之前，请从superview中[moviePlayer stop];删除movieplayer.view。之后尝试解散。那可能会解决问题。
