How to know if the iOS App you build is for 64 bit.

Question

I am trying to build an iOS Application for 64 bit. How do I know weather it is build for 32 bit or 64 bit ?

Does Mach-O-View can help ? if Yes, where to look for i

Answer 1

Try this:

#ifdef __LP64__
// NSLog(@"64");
#else
// NSLog(@"32");
#endif

It works for OS X, but I didn't test it for iOS (I don't have an iPhone5S :( ).

Edit:

By the way, it works fine on iPhone Simulator.
