cocos2d-iphone – 如何在cocos2d中获得屏幕中心？

CGSize winSize = [[CCDirector sharedDirector] winSize];
CGPoint point = ccp(winSize.width/2, winSize.height/2);

这是一种更先进的方法.
如果您在精灵的父级上调用了setPosition(在此示例中为self),这也可以工作

CGSize winSize = [[CCDirector sharedDirector] winSize];
CCSprite* centerSprite = [CCSprite spriteWithFile:@"sprite"];
CGPoint centerPoint = ccpSub(ccp(winSize.width/2, winSize.height/2), [self position]);
[centerSprite setPosition:centerPoint];
[self addChild: centerSprite];
