[https://mp.weixin.qq.com/s/ydhK8HYuRD0lZazPsPxsvg] c/c++语言具备一个不同于其他编程语言的的特性,即支持可变参数。 例如C库中的printf,scanf等函数,都支持输入数量不定的参数。printf函数原型为 int printf(const char *format, …); printf("hello world");///< 1个参数printf("%d", a);///...

struct _class_t{struct _class_t*isa;struct _class_t*superclass;void*cache;void*vtable;struct _class_ro_t*ro;}; 里面还有几个关于结构体的定义,但一下看不出头绪。然后我尝试手动分析内存,分析内存在lldb里面主要使用 x 命令。 比如x/16xg obj意思是,x显示内存,g表示按8字节读取,x表示按16进制显示...
Instead optional scalar fields get a new accessor method with the suffix _option() which returns a struct with two fiels: { is_null, value } where _option().is_null == !is_present() and _option().value is the same value is the _get() method, which will be 0 if is_null is ...
