    <p>Can anyone tell me why my code isn't showing any results in my table view. Here is my code. I already tried to change the @"@" into indexPath.row without any luck. I 'm looking for any answer into the right direction. I'm fairly new to xcode and objective-c. I would really appreciate any help. </p> <pre><code>-(void)waitAndFillPlaylistPool { // arrPlaylist -&gt; mutablearray which stores the value of loaded playlist in order to use it later [SPAsyncLoading waitUntilLoaded:[SPSession sharedSession] timeout:kSPAsyncLoadingDefaultTimeout then:^(NSArray *loadedession, NSArray *notLoadedSession) { // The session is logged in and loaded — now wait for the userPlaylists to load. NSLog(@"[%@ %@]: %@", NSStringFromClass([self class]), NSStringFromSelector(_cmd), @"Session loaded."); [SPAsyncLoading waitUntilLoaded:[SPSession sharedSession].userPlaylists timeout:kSPAsyncLoadingDefaultTimeout then:^(NSArray *loadedContainers, NSArray *notLoadedContainers) { // User playlists are loaded — wait for playlists to load their metadata. NSLog(@"[%@ %@]: %@", NSStringFromClass([self class]), NSStringFromSelector(_cmd), @"Container loaded."); NSMutableArray *playlists = [NSMutableArray array]; [playlists addObject:[SPSession sharedSession].starredPlaylist]; [playlists addObject:[SPSession sharedSession].inboxPlaylist]; [playlists addObjectsFromArray:[SPSession sharedSession].userPlaylists.flattenedPlaylists]; [SPAsyncLoading waitUntilLoaded:playlists timeout:kSPAsyncLoadingDefaultTimeout then:^(NSArray *loadedPlaylists, NSArray *notLoadedPlaylists) { // All of our playlists have loaded their metadata — wait for all tracks to load their metadata. NSLog(@"[%@ %@]: %@ of %@ playlists loaded.", NSStringFromClass([self class]), NSStringFromSelector(_cmd), [NSNumber numberWithInteger:loadedPlaylists.count], [NSNumber numberWithInteger:loadedPlaylists.count + notLoadedPlaylists.count]); NSLog(@"loadedPlaylists &gt;&gt; %@",loadedPlaylists); arrPlaylist = [[NSMutableArray alloc] initWithArray:loadedPlaylists]; NSLog(@"arrPlaylist &gt;&gt; %@",arrPlaylist); }]; }]; }]; } - (NSInteger) tableView:(UITableView *) tableView numberOfRowsInSection:(NSInteger)section { return [arrPlaylist count]; } - (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath { static NSString *CellIdentifier = @"Cell"; UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier]; if (cell == nil) { cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier]; } cell.textLabel.text = [arrPlaylist objectAtIndex:indexPath.row]; cell.accessoryType = UITableViewCellAccessoryDisclosureIndicator; return cell; } </code></pre>

    3. COYou are referring array's value incorrectly at the following line of code cell.textLabel.text = [arrPlaylist objectAtIndex:@"%@"] as you are not specifying which index the value should be taken from the array, it should be cell.textLabel.text = [arrPlaylist objectAtIndex:indexPath.row].

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
