什么是coccos2d中的CCARRAY_FOREACH？ [英] What is CCARRAY_FOREACH in coccos2d?

问题描述

我在coccos2d中看到一个宏CCARRAY_FOREACH，其实是什么呢？

I see a macro CCARRAY_FOREACH in coccos2d, actually what does it? can we do alternative solution instead of it?i am using following code for spriteBatchNode?

     CCARRAY_FOREACH([spriteBatch children], sprite)
{

    ...................
}

推荐答案

它是一个宏，用于循环遍历CCArray中的每个对象...另一种方法是客观-c的foreach for（object in array），如下所示：

it is a macro for looping through each object inside a CCArray... an alternative would be objective-c's foreach for (object in array) that goes like this:

for (CCSprite *sprite in [spriteBatch children]) {
    ...
}

$ b b

这是NSArray和NSMutableArray，但我认为它应该工作正常CCArray以及。

this is for NSArray and NSMutableArray but i think it should work fine for CCArray as well.
