Conditional compilation when using ARC

Question

Is there a way to ask the compiler if ARC is turned on, and then conditionally compile based upon that value? For example, I have a protocol:

@protocol Proto         


        

Answer 1

You should do #if __has_feature(objc_arc) That will expand to 1 in the case of ARC being enabled.

This is from the ARC docs from Clang.
