How to determine if an NSDate is today?

How to check if an NSDate belongs to today?

I used to check it using first 10 characters from [aDate description]. [[aDate description] substringToIndex:10] returns string like "YYYY-MM-DD" so I compared the string with the string returned by [[[NSDate date] description] substringToIndex:10].

Is there more fast and/or neat way to check?

Thanks.
