有按下的效果，但是没有回调按键指定的函数？这是为什么？

Question

public void menuText()
{
removeChild(intro, true);
CGSize winSize = CCDirector.sharedDirector().displaySize();
menu = CCSprite.sprite("menubg.png");
menu.setPosition(CGPoint.ccp(menu.getContentSize().width / 2.0f, winSize.height / 2.0f));
CCMenuItemFont.setFontSize(15);
CCMenuItemFont.setFontName("Marker Felt");
CCMenuItemFont newGame = CCMenuItemFont.item("New Game");
// CCMenuItemFont newGame = CCMenuItemFont.item("New Game", this, selector)
CCMenuItemFont InsGame = CCMenuItemFont.item("Instaction",this,"instr");
// CCLabel label, CCNode rec, String cb
CCMenuItemFont snd = CCMenuItemFont.item("Sound on");
CCMenuItemFont ab = CCMenuItemFont.item("About FuguMobile");
CCMenuItemFont exit = CCMenuItemFont.item("Exit");
CCMenu mu= CCMenu.menu(newGame,InsGame,snd,ab,exit);
mu.setPosition(CGPoint.ccp(130.0f,130.0f));
mu.alignItemsVertically(10.0f);
// mu.ccAccelerometerChanged(10.0f, 10.0f, 0.0f);
addChild(menu);
addChild(mu);
// menu.setTag(2);
}
public void instr()
{
inst = CCSprite.sprite("inst.png");
CGSize winSize = CCDirector.sharedDirector().displaySize();
inst.setPosition(CGPoint.ccp(inst.getContentSize().width / 2.0f, winSize.height / 2.0f));
addChild(inst);
// intro.setTag(3);
}
public boolean ccTouchesEnded(MotionEvent event)
{
intro.runAction(CCSequence.actions(CCCallFuncN.action(this, "spriteMoveFinished")));
return true;
}
public void spriteMoveFinished(Object sender)
{
CCSprite sprite = (CCSprite)sender;
if (sprite.getTag() == 1)
{
menuText();
}
// if(sprite.getTag() == 3)
// {
// menuText();
// }
this.removeChild(sprite, true);
}
这是原码，求教~~

这个应该是cocos2d-x吧，我只写过cocos2d，总得来说intro这个对象在touchend里面执行的跳转函数动作，但是貌似在touch事件触发之前这个对象就已经被remove了，所以导致的问题

我着实没看懂你事怎么写的。至少应该有：CCMenuItemFont *font = [CCMenuItemFont itemWithTarget:self selector:@selector(myMethod:)];吧！现在没有selector添加的地方啊！这里有一个CCMenu的例子；CCMenuItem *starMenuItem = [CCMenuItemImage itemFromNormalImage:@"ButtonStar.png" selectedImage:@"ButtonStarSel.png" target:selfselector:@selector(starButtonTapped:)];starMenuItem.position = ccp(60, 60);CCMenu *starMenu = [CCMenu menuWithItems:starMenuItem, nil];starMenu.position = CGPointZero;[self addChild:starMenu];然后相应函数starButtonTapped，就可以有相应了。
