Question

Is there anything like C++s safe casts in Objective-C?

I know that they are in Objective C++, but I am unsure about possible side effects. Using Objective C++ may slow compilation time – are there any other reasons not to use it?

Answer 1

Objective-c does have C++ safe casts. Alternatively, we can use runtime reflection:

id myOb=[someObject getObject];
NSAssert([myOb isKindOfClass:[MyClass class]], @"Return value is not of type MyClass as expected.");
MyClass * newOb= (MyClass *)myOb;
