Hi there! I think I addressed that in the video right after that (it's been a few months since I recorded it). Check it out and let me know if that doesn't work.

Yeah it should work.. I remember doing this app, it was awesome! Kelvin if you get stuck let me know. Post the code, and I'll help you.

I believe I finally found the problem. To quickly reproduce the error, I went to the final video in this series and downloaded Diary-Stage6-Video5.zip. Run the app and add some entries. No matter what mood you select, the main list view will always display a good mood.

The problem lies in the THEntryViewController.m file. For me, this is line 110 within the insertDiaryEntry method.

- (void)insertDiaryEntry {
    THCoreDataStack *coreDataStack = [THCoreDataStack defaultStack];
    THDiaryEntry *entry = [NSEntityDescription insertNewObjectForEntityForName:@"THDiaryEntry" inManagedObjectContext:coreDataStack.managedObjectContext];
    entry.body = self.textView.text;
    entry.date = [[NSDate date] timeIntervalSince1970];
    entry.imageData = UIImageJPEGRepresentation(self.pickedImage, 0.75);
    entry.location = self.location;
    self.entry.mood = self.pickedMood; // <----- THIS LINE
    [coreDataStack saveContext];

The entry isn't being saved properly. This should be:

entry.mood = self.pickedMood;

It's possible I missed something in the series. However, I don't ever remember this being addressed and I had this bug in my final version of the app and the final project files I downloaded just a few minutes ago.

I had the same problem and answers above didn't help me. So I solved it myself! (:<br /> The problem was in "updateDiaryEntry" method. Ash didn't cover this in the video (that's why all his entries have "Good" mood).<br /> So everything you need to do is to make this method to save mood, not just body text:<br />

- (void) updateDiaryEntry {
    self.entry.body = self.textField.text;
    self.entry.mood = self.pickedMood; // <-- This line!

    JDCoreDaraStack *coreDataStack = [JDCoreDaraStack defaultStack];
    [coreDataStack saveContext];

I hope it will help you as well.

Here is the code:

-(void)configureCellForEntry:(MavDiaryEntry *)entry {
    self.bodyLabel.text = entry.body;
    self.locationLabel.text = entry.location;

    NSDateFormatter *dateFormatter = [[NSDateFormatter alloc] init];
    [dateFormatter setDateFormat:@"EEEE, MMMM d yyyy"];
    NSDate *date = [NSDate dateWithTimeIntervalSince1970:entry.date];

    self.dateLabel.text = [dateFormatter stringFromDate:date];

    if (entry.imageData) {
        self.mainImageView.image = [UIImage imageWithData:entry.imageData];
    }else {
        self.mainImageView.image = [UIImage imageNamed:@"icn_noimage"];

    if (entry.mood == MavDiaryEntryMoodGood) {
        self.moodImageView.image = [UIImage imageNamed:@"icn_happy"];
    } else if (entry.mood == MavDiaryEntryMoodAverage) {
        self.moodImageView.image = [UIImage imageNamed:@"icn_average"];
    } else if (entry.mood == MavDiaryEntryMoodBad) {
        self.moodImageView.image = [UIImage imageNamed:@"icn_bad"];
    self.mainImageView.layer.cornerRadius = CGRectGetWidth(self.mainImageView.frame) / 2.0f;

    if (entry.location.length > 0) {
        self.locationLabel.text = entry.location;
    }else {
        self.locationLabel.text = @"Somewhere on Earth";

It's working for me just fine : )

I just completed the last video thinking this functionality would be implemented and it wasn't. To double check my code I downloaded the final project files from the last video and ran the app. Moods do not change no matter what selection you make. If it was covered, that code didn't make it into the final project files.

Did you try the code above?
