Custom allocator: By default when using the heap, the standard library's malloc, free, and realloc functions are used; to use a custom allocator, specify -DINI_CUSTOM_ALLOCATOR=1 (and -DINI_USE_STACK=0). You must define and link functions named ini_malloc, ini_free, and (if INI_ALLOW...
For example, instead of allocator_traits<A>::rebind_alloc<U>::other, now you have to say allocator_traits<A>::rebind_alloc<U>. Although ratio_add<R1, R2>::type is no longer necessary and we now recommend that you say ratio_add<R1, R2>, the former will still compile because ratio...
例如,现在必须使用 allocator_traits<A>::rebind_alloc<U>::other,而不是 allocator_traits<A>::rebind_alloc<U>。 虽然 ratio_add<R1, R2>::type 不再必要且我们现在建议宣称 ratio_add<R1, R2>,但前者仍会进行编译,因为 ratio<N, D> 需要具有一个“type”typedef 以用于缩减比(如果已缩减,将为相同...
free(p); // Replace this with alternative de-allocator } 所有TestClass对象的内存分配都采用这段代码。更进一步,任何从TestClass继承的类也都采用这一方式,除非它自己也重载了new和 delete操作符。通过重载new和 delete操作符的方法,你可以自由地采用不同的分配策略,从不同的内存池中分配不同的类对象。

I have a class object created dynamically using Runtime, and I want to release some manually allocated memory resources when this object is deallocated. To achieve this, I added a custom implementation of the dealloc method using the following code: SEL aSel = NSSelectorFromString(@"dealloc"); ...
