Question

我正在尝试使用自定义动画删除CCMenuItem并崩溃...

- (void)removeCCMenuItem:(id)sender {

    CCMenuItemSprite *menuItem = (CCMenuItemSprite *)sender;

    CCSprite *animationSprite = [CCSprite spriteWithSpriteFrameName:@"AnimatedImage_01.png"];

    [fixedSprite setScaleX: menuItem.contentSize.width/animationSprite.contentSize.width];
    [fixedSprite setScaleY: menuItem.contentSize.height/animationSprite.contentSize.height];

    animationSprite.position = ccp(menuItem.contentSize.width/2,menuItem.contentSize.height/2);
    [menuItem addChild:animationSprite];

    NSMutableArray *animFrames = [NSMutableArray array];
    for(int i = 1; i <= 5; ++i) {
        [animFrames addObject: [[CCSpriteFrameCache sharedSpriteFrameCache] spriteFrameByName: [NSString stringWithFormat:@"AnimatedImage_%02d.png", i]]];
    }

    CCAnimation *anim = [CCAnimation animationWithFrames:animFrames delay:0.05f];
    CCActionInterval *animAction = [CCAnimate actionWithAnimation:anim restoreOriginalFrame:NO];

    id seq = [CCSequence actions: animAction, [CCCallFunc actionWithTarget:animationSprite selector:@selector(removeFromParentAndCleanup:)], [CCCallFunc actionWithTarget:menuItem selector:@selector(removeFromParentAndCleanup:)], nil];
    [menuItem runAction:seq];
}

知道它崩溃的原因吗？

日志说：

reason: '-[CCMenuItemSprite isFrameDisplayed:]: unrecognized selector sent to instance

您正在CCMenuItem的子类上运行该操作，而在这种情况下，我认为您需要在精灵本身上运行它。

尝试更改：

[menuItem runAction：seq];

要：

[animationSprite runAction：seq];

使用动画cocos2d删除ccmenuitem
