通过名称创建Objective-C类实例吗? [英] Create objective-c class instance by name?

问题描述

是否可以通过名称创建类的实例?像这样:

Is it possible to create an instance of a class by name? Something like:

NSString* className = @"Car";
id* p = [Magic createClassByName:className];
[p turnOnEngine];

我不知道在Objective-C中这是否可行，但似乎可以实现，

I don't know if this is possible in objective-c but seems like it would be,

推荐答案

id object = [[NSClassFromString(@"NameofClass") alloc] init];
