NSLog warning format string is not a string literal

Question

I am trying to log the segue identifier for debugging purpose.

I tried this:

NSString * string = [NSString stringWithFormat:@"test %@", segue.identifier];
        NSLog(string);

and I tried this:

NSLog([NSString stringWithFormat:@"test %@", segue.identifier]);

In both ways, Xcode shows a warning message states that format string is not a string literal

Why it is not string? I checked the segue.identifier property and it is from type NSString *

I am using Xcode 5.0.2 on OS 10.9

I appreciate your help.

Regards,
