需求：获取uiimage的rgb值保存到数组
内存泄漏：我用了好几个方法都出现了内存泄漏
工作效率：会在一个死循环一直调用，我尝试用消息事件来获取数据失败告终，直接获取数据失败告终！
求大神告诉我一下，感谢
运行调用这个游戏就慢慢的越来越卡越来越卡，到底是哪里没有释放掉啊，我想释放imageref但是会奔溃就直接用了，还是会越来越卡然后崩溃掉
怎么查能看内存泄漏啊，或者调试

就是这个函数崩溃，循环data太多次了就崩溃，应该怎么办
up谁帮帮忙吧，感谢了
opencv可以根据某点查找像素怎么做啊
self.data=malloc()
这个里面没有必要每次都去重新申请一个内存
这个函数没有问题的，解决了这个函数就贡献了，我还有一个高级的算法哈哈
说下 我个人建议吧。
第一，每个函数尽量不要超过30行。自己回头看也清晰，别人看你代码也清晰。
如果一个函数太长…没心思看下去…更别说找问题
第二点嘛，就是层次化明了点，一个算法的清晰执行下去。出了问题的话，也一目了然
第三点嘛，既然是搞图色模拟，建议去 玩玩触动，想自己玩的话，可以去逆他，也可以去 github上去搜索别人的开源软件，，其中就有很多文章项目，关于图色处理的
第四点嘛，就是提问题，尽量明确化…丢一串代码…说个表象…谁都没办法解决
这是个骗人钱的骗子

骗子，尽然混到技术堆了
