I'm assuming this was resolved.

Hi Amit,

First - thank you so much for your awesome tutorials. I am having a similar problem. I was able to easily get to the titles/author in your example using the team treehouse api. however, i am now trying to use this YouTube API:

https://gdata.youtube.com/feeds/api/users/CrossFitHQ/playlists?v=2&alt=json

I used the same methodology, but I think the error I'm getting has to do with the fact that I have dictionaries nested in arrays and I need to somehow specify which child is a dictionary and which is an array.

Ultimately, I'm trying to get the following fields from the "-entry":

"title" (the true title is also contained in a strange "$t" key) "content" > "src": essentially the url of the playlist

Thank you VERY VERY much, Amit Bijlani.

Glad you are enjoying the tutorials! These are very nested entries and you could use the method valueForKeyPath. So for example if your parsed data is stored in a dictionary called dictionary then you should be able to access it:

// entries is an array of dictionaries
NSArray* entries = [dictionary valueForKeyPath:@"feed.entry"];

NSDictionary *firstItem = [entries objectAtIndex:0];

NSString *title = [firstItem objectForKey:@"title"];
NSString *src = [firstItem objectForKey:@"src"];

The above code is not tested so I can't guarantee it works but it should give you the general idea. Once you have the entries array you can create your table view because it contains dictionaries with the related title/src.

• (void)viewDidLoad { [super viewDidLoad]; NSURL *feedURL = [NSURL URLWithString:@"https://gdata.youtube.com/feeds/api/users/Crossfithq/playlists?v=2&alt=json"]; NSData *jsonData = [NSData dataWithContentsOfURL:feedURL]; NSError *error = nil; NSDictionary *dataDictionary = [NSJSONSerialization JSONObjectWithData:jsonData options:0 error:&error];

  NSArray *entry = [dataDictionary valueForKeyPath:@"feed.entry"]; NSDictionary *firstItem = [entry objectAtIndex:5]; NSString *title = [firstItem valueForKeyPath:@"title.$t"];

  NSLog(@"the title is %@", title); /* self.blogPosts = [dataDictionary valueForKey:@"sports"]; NSArray *dataArray = [dataDictionary valueForKey:@"leagues"]; self.leaguesDictionary = [dataArray valueForKey:@"name"]; */ }

• (void)didReceiveMemoryWarning { [super didReceiveMemoryWarning]; // Dispose of any resources that can be recreated. }

pragma mark - Table view data source

• (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView {

  return 1; }

• (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section {

  return [self.feeds count]; }

• (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath { static NSString *CellIdentifier = @"Cell"; UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier forIndexPath:indexPath];

  // Configure the cell...

  NSDictionary *feed = [self.feeds objectAtIndex:indexPath.row];

  cell.textLabel.text = [feed valueForKey:@"title"]; //cell.detailTextLabel.text = [blogPost valueForKey:@"uid"];

  return cell; }

sorry Amit ...i tried to do the code block...didn't work

Hi Amit Bijlani - thanks for your help...i just figured out how to load the array of entries using your valueForKeyPath recommendation. I also have it displaying on the tableView.

Thanks!
