如何将声音效果与动画同步（CCAnimation）

        NSMutableArray* animationframes = [NSMutableArray array];
        [animationframes addObject:[[[CCAnimationFrame alloc] initWithSpriteFrame:[TitleLayer spriteframeForFile:@"title_startanime01.png"] delayUnits:1 userInfo:nil] autorelease]];
        [animationframes addObject:[[[CCAnimationFrame alloc] initWithSpriteFrame:[TitleLayer spriteframeForFile:@"title_startanime02.png"] delayUnits:1 userInfo:nil] autorelease]];
        [animationframes addObject:[[[CCAnimationFrame alloc] initWithSpriteFrame:[TitleLayer spriteframeForFile:@"title_startanime03.png"] delayUnits:1 userInfo:nil] autorelease]];
        [animationframes addObject:[[[CCAnimationFrame alloc] initWithSpriteFrame:[TitleLayer spriteframeForFile:@"title_startanime04.png"] delayUnits:1 userInfo:nil] autorelease]];
        [animationframes addObject:[[[CCAnimationFrame alloc] initWithSpriteFrame:[TitleLayer spriteframeForFile:@"title_startanime05.png"] delayUnits:1 userInfo:nil] autorelease]];
        [animationframes addObject:[[[CCAnimationFrame alloc] initWithSpriteFrame:[TitleLayer spriteframeForFile:@"title_startanime06.png"] delayUnits:1 userInfo:nil] autorelease]];
        CCAnimation* animation = [CCAnimation animationWithAnimationFrames:animationframes delayPerUnit:0.09 loops:1];

我可以以某种方式向animationframes数组添加一个callblock吗？

如果CCAnimationFrame在激活时有一个可选的回调/委托，它可以工作。

好的，我们所要做的就是：

观察通知CCAnimationFrameDisplayedNotification。它被调用了动画的精灵。

为了要播放的通知，需要添加字典到你要挂钩的CCSpriteFrame。我添加了一个NSDictionary 包含所有spriteframe的每个sprite的spriteframename 因为我需要挂钩所有这些，但我想字典可以也是空的，不是nil。

    animationframe = [[[CCAnimationFrame alloc] initWithSpriteFrame:[cache spriteFrameByName:str] delayUnits:1 userInfo:nil] autorelease];
    animationframe.userInfo = [NSDictionary dictionaryWithObjectsAndKeys:str, @"spriteframename", nil];
    [animationframes addObject:animationframe];

    [[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(frameupdatedinbootanimation:) name:CCAnimationFrameDisplayedNotification object:NULL];

然后抓住它

-(void)frameupdatedinbootanimation:(id)hmm {
    NSLog(@"frameupdatedinbootanimation: %@", hmm);
    Do something here
