Thoughts on adding a simple macro based solution (for non-persisted)?

Macro

#define RateLimit(SECS) \
({ \
    static NSDate *lastCall = nil; \
    ^(dispatch_block_t block) { \
        @synchronized(lastCall) { \
            if (!lastCall || fabs(lastCall.timeIntervalSinceNow) > SECS) { \
                lastCall = NSDate.date; \
                block(); \
            } \
        } \
    }; \
})

Usage

RateLimit(60.0)(^{
    // Do some work that runs a maximum of once per minute
});

Thanks @mhuusko5. Not a big fan though. In my opinion, macros are a code smell. This also won't work with Swift. Feel free to use in your own project though!

Fair enough :)
