Runtimepolymorphism.Also known as dynamic polymorphism,runtimepolymorphism uses method overridingto let a child class have its own definition of a method belonging to the parent class. This type of polymorphism is often associated with upcasting, which happens when a parent class points to an instan...
Polymorphism may have a slight impact on performance compared to direct method calls. This is because polymorphic method invocations involve an extra level of indirection and dynamic binding, which can introduce some overhead. However, modern compilers and runtime systems have optimizations in place to...

6.What is purpose of delegates? 代理的作用? 答案:代理的目的是改变或传递控制链。允许一个类在某些特定时刻通知到其他类,而不需要获取到那些类的指针。可以减少框架复杂度。 另外一点,代理可以理解为java中的回调监听机制的一种类似。 7.What are mutable and immutable types in Objective C? oc中可修改和不...
