Question

这是我在3.1.3播放视频时遇到的崩溃。它在4.0上工作正常。

*** Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '*** -[UIWindow addEventMonitor:]: unrecognized selector sent to instance 0x127500'

任何答案都会有所帮助。谢谢，

播放视频在os 3.0+和os 4.0+之间的处理方式不同，也是出于什么原因使用addEventMonitor？

我是这样做的：

-(void)playStoryMovie {
NSURL *url = [NSURL fileURLWithPath:[[NSBundle mainBundle] pathForResource:@"campaign1" ofType:@"mp4"]];
MPMoviePlayerController *moviePlayer = [[MPMoviePlayerController alloc] initWithContentURL:url];
// Register to receive a notification when the movie has finished playing.
[[NSNotificationCenter defaultCenter] addObserver:self
                                         selector:@selector(moviePlayBackDidFinish:)
                                             name:MPMoviePlayerPlaybackDidFinishNotification
                                           object:moviePlayer];

if ([moviePlayer respondsToSelector:@selector(setFullscreen:animated:)]) {
    // Use the new 3.2 style API
    moviePlayer.controlStyle = MPMovieControlStyleNone;
    moviePlayer.shouldAutoplay = YES;
    // This does blows up in cocos2d, so we'll resize manually
    // [moviePlayer setFullscreen:YES animated:YES];
    [moviePlayer.view setTransform:CGAffineTransformMakeRotation((float)M_PI_2)];
    CGSize winSize = [[CCDirector sharedDirector] winSize];
    moviePlayer.view.frame = CGRectMake(0, 0, winSize.height, winSize.width);   // width and height are swapped after rotation
    [[[CCDirector sharedDirector] openGLView] addSubview:moviePlayer.view];
} else {
    // Use the old 2.0 style API, YES APPLE WE KNOW ITS DEPRECATED BUT THIS IS FOR THE OLD DEVICES.
    moviePlayer.movieControlMode = MPMovieControlModeHidden;
    [moviePlayer play];
}   


}

- (void)moviePlayBackDidFinish:(NSNotification*)notification {
    MPMoviePlayerController *moviePlayer = [notification object];
    [[NSNotificationCenter defaultCenter] removeObserver:self
                                                    name:MPMoviePlayerPlaybackDidFinishNotification
                                                  object:moviePlayer];

    // If the moviePlayer.view was added to the openGL view, it needs to be removed
    if ([moviePlayer respondsToSelector:@selector(setFullscreen:animated:)]) {
        [moviePlayer.view removeFromSuperview];
    }

    [moviePlayer release];  
}
