电影播放时如何设置菜单 - iphone cocos2d

Question

我使用以下代码播放电影

NSString *path = [[NSBundle mainBundle] pathForResource:@"cobra" ofType:@"mp4"];

theMovie=[[MPMoviePlayerController alloc] initWithContentURL:[NSURL fileURLWithPath:path]];
theMovie.scalingMode=MPMovieScalingModeAspectFill;
// Add an observer to catch when playback ends
[[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(transition:) 
                                             name:MPMoviePlayerPlaybackDidFinishNotification object:theMovie];
// Start playback
theMovie.movieControlMode = MPMovieControlModeDefault;
[theMovie play];

现在我想在播放电影上有一个菜单.我的代码就像

MenuItemImage *item1 = [MenuItemImage itemFromNormalImage:@"Button_cobra.png" selectedImage:@"Button_cobra1.png" target:self selector:@selector (transition:)];
Menu *menu = [Menu menuWithItems:item1, nil];
menu.position = CGPointZero;
item1.position = ccp(330,260);
item1.scale = 0.5;
[self addChild:menu z:51];
NSLog(@"Leaving Layer2");

但是菜单没有显示出来.任何人都可以告诉我该怎么做.

你必须等到窗口加载然后做这样的事情.

NSArray *windows = [[UIApplication sharedApplication] windows];
if ([windows count] > 1)
{
    // Locate the movie player window
    UIWindow *moviePlayerWindow = [[UIApplication sharedApplication] keyWindow];
    // Add our overlay view to the movie player's subviews so it is 
    // displayed above it.
    PlayerOverlayView *overlay = [[PlayerOverlayView alloc]initForPlayerWithButtonDelegate:self];
    [moviePlayerWindow addSubview:overlay];
    [overlay release];
}

PlayerOverlayView没什么特别的.只是我做的UIView子类.我叫这个

- (void) moviePreloadDidFinish:(NSNotification*)notification

回调,效果很好.
