Since upgrading to the latest XCode 3.2.1 and SnowLeopard, I've been getting the warning,
"format not a string literal and no format arguments"
on the following:
NSError *error = nil;
if (![self.managedObjectContext save:&error])
{
NSLog([NSString stringWithFormat:@"%@ %@, %@",
errorMsgFormat,
error,
[error userInfo]]);
}
If 'errorMsgFormat' is an NSString with format specifiers (eg: "print me like this: %@"), what is wrong with the above NSLog statement? And what is the recommended way to fix it so that the warning isn't generated?
