So I'm on the the code challenge for "Adding Friends by Tapping on a Table View Cell" which asks:
"In this Code Challenge we are working on an app to download videos of the Treehouse Show, which are listed in a table view. Create a list of shows to download by adding the code below to mark rows as selected or not using 'UITableViewCellAccessoryCheckmark' and 'UITableViewCellAccessoryNone'."
For my code I'm thinking it will need to be something like this (since we're just following the adding stage:
if (cell.accessoryType == UITableViewCellAccessoryNone) {
}
else {
PFRelation *moviesRelation = [self.currentUser relationForKey:@"moviesRelation"];
PFUser *user = [self.allUsers objectAtIndeX:indexPath.row];
[moviesrelation addObject:user];
[self.currentUser saveInBackgroundWithBlock:^(BOOL succeeded, NSError *error) {
}];
}
Any suggestions?

29,247 PointsThis challenged stumped me too. I had to read the challenge description a few times before it clicked. And the answer turned out to be not very complicated.
The key phrase in the description is, mark rows as selected or not using 'UITableViewCellAccessoryCheckmark' and 'UITableViewCellAccessoryNone'. All the challenge wants you to do is set the cell.accessoryType property to be either 'UITableViewCellAccessoryCheckmark' or 'UITableViewCellAccessoryNone'. Based on whether or not it met the condition in the 'if' statement.
if (cell.accessoryType == UITableViewCellAccessoryNone) {
cell.accessoryType = UITableViewCellAccessoryCheckmark;
}
else {
cell.accessoryType = UITableViewCellAccessoryNone;
}

7,780 PointsAh gotcha, basically just testing to see if the video already been checked, and if not then check it.
That makes a lot more sense, thanks for breaking that down.

17,041 PointsThanks for the help with this challenge. I am really enjoying Treehouse, however, I do find the challenge questions a lot of the time quite ambiguous and confusing. I might just need to break the questions down a little more!

17,041 PointsI guess it is hard to write questions that everyone can understand considering that programming has its own unique language / lingo. Whoever writes the questions has to take into consideration that a lot of people come from different language backgrounds as well as different English speaking countries and cultures as well.
I think on the whole they do a good job with the questions (otherwise we wouldn't pay our monthly subscription), but sometimes it can be frustrating if you can understand what the question is asking you to do, but I am getting the hang of it.
I just want my next badge :-)
