Can I use property for C++ variable?

Question

I am using Objective-C++. Can I create a property of C++ class type?

I tried but it reports must be inherited from NSObject.

Answer 1

You can, but it cannot be a strong or weak reference (if you need that, look up std::shared_ptr and std::weak_ptr).

class C {};

@interface D

@property(nonatomic, assign) C p;

@end
