Question

I have a non-ARC project that I added a new file to and set an ARC compiler flag (-fobjc-arc) for. When I make calls to [object release]; in the file, there are no compiler errors thrown. I need to be sure that this file indeed has ARC enabled, how can I prove that? Thanks.

Answer 1

There is no check for ARC at runtime. However, you can check it at compile time:

#if !__has_feature(objc_arc)
    //Do the old stuff
#endif

Hope that helps.
