Stuck on "Adding Friends By Tapping On a Table View Cell" code challenge.

Hey guys,

So I've been sitting and looking at my screen scratching my head and I'm completely lost for the answer and wondering if anyone has any advice for how I can get it right.

The code challenge asks...

"We are working on an app to download videos of the Treehouse Show, which are listed in a table view. The user will tap on items in the list to create a list of shows to download. For each tap, add code below to simply mark rows as selected or not using 'UITableViewCellAccessoryCheckmark' and 'UITableViewCellAccessoryNone'."

I'll keep working to get an answer.

Thanks

Stu :)

So I finally I got it and in my research in the forum I came across this and I'll quote Andres Mauricio Guerrero

**well, I´m going to try to help you by giving as little to no code as possible, you have this "if" condition:

if (cell.accessoryType == UITableViewCellAccessoryNone) { } else { }

first know what´s being asked, then understand your if condition, if for each tap you want to mark your row as checked or unchecked then you could see that your'e doing opposite tasks here, so knowing that, the you go to the "if" condition.

this condition what is telling us in our human language is "if the cell that we touched has nothing on it (in this case unchecked), then do... else, do the opposite thing" so what do we want to do if the cell is unchecked? and what do we want to do if the cell is checked (else statement)? hope this helps you, let me know ;)**

This pretty much helped me to get the correct answer!
