问题描述

我使用以下代码播放电影

I play a movie using the following code

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];

现在我想在正在播放的电影上有一个菜单.我的代码像

now i want to have a menu over the playing movie.I code like

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");

但菜单没有显示.谁能告诉我怎么做.

But the menu is not getting displayed. Can anyone please tell me how to do it.

推荐答案

你必须等到窗口加载完毕，然后再做这样的事情.

You have to wait until the window is loaded and then do something like this.

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.只是我制作的 UIView 子类.我是从

PlayerOverlayView is nothing special. Just a UIView subclass i made. I call this from the

- (void) moviePreloadDidFinish:(NSNotification*)notification

回调，效果很好.
