Question

I use this little snippet to halt my iPhone app in the simulator.

NSAssert((0), @"Bail early while testing");

When I try to make it a #defined macro like this:

#define BAILNOW (NSAssert((0), @"Bail early while testing"))

I get this build error:

error: expected expression before ‘do’

It seems to be related to the nesting of the NSAssert() macro but I’m at a loss as to how to get around it. Should I dig into the NSAssertionHandler docs or is there some simpler way to halt the app in it’s tracks? Or should I just set a breakpoint and get on with my life?

Answer 1

#define BAILNOW NSAssert(0, @"Bail early while testing")

Just remove the brackets and this will succesfully be compiled. But I dont test the code in runtime.
