#define offsetof(TYPE, MEMBER) ((size_t) &((TYPE *)0)->MEMBER)

#define offsetof(TYPE, MEMBER) ((size_t) &((TYPE *)0)->MEMBER)宏的运行机理:1. ( (TYPE *)0 ) 将零转型为TYPE类型指针; 2. ((TYPE *)0)->MEMBER 访问结构中的数据成员; 3. &( ( (TYPE *)0 )->MEMBER )取出数据成员的地址; 4.(size_t)(&(((TYPE*)0)->MEMBER))结果转换类型.巧妙之处在于将0转换成(TY…

swift 中Value Type VS Class Type

ios 中Value Type 和 Class Type 有哪些异同点,这个问题是在微信的公共帐号中看到的,觉得挺有意思,这里梳理一下. 1.swift 中为什么要设置值类型? 值类型在参数传递.赋值的过程中采用的是Copy的过程,copy的"值"是该值所在的内存块,相比于class类型,copy更直接,没有对象中方法调用(饮用计数.copy方法等),因此效率更高.猜测swift引入的值类型主要是为了提高效率. 2.swift 存在哪些值类型 swift中常见的值类型有 struct,…
