Question about a Code Challenge.

I am working on the Code Challenge for Formatting Dates with NSDateFormatter.

Question: Using NSDate create a date object that is 10 days from today and call it 'futureDate'.

Why is the following code not acceptable?

NSTimeInterval futureDate = (60 * 60 * 24) * 10;

NSDate *future = [NSDate dateWithTimeIntervalSinceNow:futureDate];

looks like you are missing an opening parenthesis. That could be causing your problem.

oops that was a typo in this post, but i tried it in the code challenge also and no luck.

I think they want to see a particular syntax even though there are several ways to accomplish.

Are you sure your numbers are right? 960 seems like way too big of a number. NSTimeInterval is seconds I believe. So you should have 60 seconds * 60 to give you seconds in an hour * 24 to give you seconds in a day * 10 to give you seconds in 10 days.

Oh I see now. Your date Object needs to be called *futureDate not *future. Also your unit conversion is not right. Should be 60 * 60 * 24 *10 not 960. But im guessing thats just a typo from typing parenthesis

Sorry that was a typo.

I will try this syntax and see what happens.

NSTimeInterval future = (60 * 60 * 24) * 10; NSDate *futureDate = [NSDate dateWithTimeIntervalSinceNow:future];
