OC 的类可以继承swift 的类,但是不要新建一个OC文件,在OC中写一个类继承 swift 的类

场景 在传统C++中,经常容易发现意外重载虚函数的事情: struct Base { virtual void foo(); }; struct SubClass: Base { void...foo(); }; 有下列三种场景: SubClass::foo可能是程序员加入的一个和基类虚函数恰好同名的成员函数,却被编译器当作重载虚函数 SubClass::foo可能是程序员想重载虚函数,...struct Base { virtual void foo(int); }; struct SubClass: Base { virtual void foo(int) override...struct Base { virtual void foo() final; }; struct SubClass1 final: Base { }; // 合法 struct SubClass2...: SubClass1 { }; // 非法, SubClass1已final struct SubClass3: Base { void foo(); // 非法, foo已final
