I have re-watched the video several times and download the project to view his code, but I can't seem to find what I am doing wrong. Help is appreciated :)

Treehouse TeacherYour code looks good. Debug it and see if the objects variable has anything in it when findObjectsInBackgroundWithBlock is called. If it does then you'll need to then debug cellForRowAtIndexPath to see why data isn't showing.

3,128 PointsI had this same problem and it was a similar fix, but I didn't have a typo. The Parse key now has "FriendsRelation" capitalized, unlike when this video was made. So when you type that part in pink 2 posts above in Ben's post, make sure the @"friendsRelation" is actually @"FriendsRelation"

15,791 PointsHi Ben,
I debugged findObjectsInBackgroundWithBlock and it ran good, but after I put another break point at cellForRowAtIndexPath and the application did not stop and just kept running. So that means cellForRowAtIndexPath is not being executed by the application. Right? If that is the issue, how can I fix it?
Thank you for helping me out with this problem :)

Treehouse TeacherI ran your app in debug mode and
self.friendsRelationis nil, which means it isn't getting set properly. I took a look at your code and I found a typo where you are creating the friendsRelation field in the EditFriendsViewController class:PFRelation *friendsRelation = [self.currentUser relationForKey:@"firendsRelation"];Change the name to match and you should be set!
As a side note, I should have put these "magic" string names into constants that could be defined once and reused throughout the app. I ended up doing that in the Android version. Doing it that way prevents any problems like this.
