这个示例代码中,一个SuperClass实现了+(void)load和+(void)initialize方法(实际上应该算是重写覆盖了NSObject的这两个方法);ChildClass继承于SuperClass,但是只重写+(void)initialize没有+(void)load;Insideinitialize类也有+(void)load和+(void)initialize方法,它在ChildClass的i+(void)initialize方法中被构建出一个...
、、 它的DllGetClassObject函数似乎正在调用第三方库的一些初始化函数,该函数依赖于要完成的静态初始化(因此不能在常规C++程序中的main()之前调用它)。这一功能似乎是失败的,并没有显示在MMC中。奇怪的是,如果我从MMC中删除它并再次添加它,它就会成功加载。关于DLL中何时发生C++静态初始化的信息(在回调之前和...

The load message is sent to classes and categories that are both dynamically loaded and statically linked, but only if the newly loaded class or category implements a method that can respond. The order of initialization is as follows:

enum class my_type : size_t {}; 然后,更改对 placement new 和 delete 的定义,以使用此类型作为第二个自变量(而不是 size_t)。 你还需要更新对 placement new 的调用以传递新类型(例如,通过使用 static_cast<my_type> 从整数值转换)并更新 new 和delete 的定义以强制转换回整数类型。 你无需为此使用...
