Stumbled on this one somewhere…

#define PrintName NSLog(@”?”, __FUNCTION__);

@Tim: A bridge cast seems to do the trick:

#define debug(format, …) CFShow((__bridge void *)[NSString stringWithFormat:format, ## __VA_ARGS__]);

It doesn’t work with ARC, I get the following:

error: Automatic Reference Counting Issue: Implicit conversion of an Objective-C pointer to ‘CFTypeRef’ (aka ‘const void *’) is disallowed with ARC

Any thoughts?

Thanks for the post.

I added #define NSLog(…) CFShow([NSString stringWithFormat:__VA_ARGS__])
to MyApp_Prefix.pch and it works beautifully.

I agree, printf will work fine as you’ve shown, however, with printf you need to call the appropriate method to convert each object to its string representation or call the description method on the object. NSLog and/or CFShow will handle this process for you.

Why not just use printf? You could do the following:

NSDate *today = [NSDate date];
NSDateFormatter *dateFormat = [[NSDateFormatter alloc] init];
[dateFormat setDateFormat:@"EEEE MMMM d, YYYY"];
NSString *dateString = [dateFormat stringFromDate:today];
[dateFormat release];

…

NSLog(@”Date: %@”, dateString);
printf(“Date: %s”, [dateString cString]);
