    <p>I have an array of dictionaries in an iOS .plist structured similar to the following:</p> <pre><code>&lt;plist version="1.0"&gt; &lt;array&gt; &lt;dict&gt; &lt;key&gt;name&lt;/key&gt; &lt;string&gt;Afghanistan&lt;/string&gt; &lt;key&gt;government&lt;/key&gt; &lt;string&gt;Islamic Republic&lt;/string&gt; &lt;key&gt;population&lt;/key&gt; &lt;integer&gt;29121286 &lt;/integer&gt; &lt;/dict&gt; &lt;dict&gt; &lt;key&gt;name&lt;/key&gt; &lt;string&gt;Albania&lt;/string&gt; &lt;key&gt;government&lt;/key&gt; &lt;string&gt;Emerging Democracy&lt;/string&gt; &lt;key&gt;population&lt;/key&gt; &lt;integer&gt;2986952&lt;/integer&gt; &lt;/dict&gt; </code></pre> <p> </p> <p>I am trying to load the <code>&lt;key&gt;name&lt;/key&gt;</code> from each dictionary into an NSTableViewCell then display them all alphabetically in an NSTableView similar to the Contacts App in iOS.</p> <p>Below are my ViewControllers .h and .m. The sort is working, but I am not able to load the results into the TableViewCells? </p> <p><strong>FirstViewController.h</strong> </p> <pre><code>#import &lt;UIKit/UIKit.h&gt; @interface FirstViewController : UIViewController &lt;UITableViewDelegate,UITableViewDataSource&gt; { NSArray *sortedCountries; } @property (nonatomic, retain) NSArray *sortedCountries; @end </code></pre> <p><strong>FirstViewController.m</strong></p> <pre><code>#import "FirstViewController.h" @implementation FirstViewController @synthesize sortedCountries; -(void)viewDidLoad { NSString *path = [[NSBundle mainBundle] pathForResource:@"countries"ofType:@"plist"]; NSArray *countries = [NSArray arrayWithContentsOfFile:path]; NSSortDescriptor *descriptor = [[[NSSortDescriptor alloc] initWithKey:@"name" ascending:YES] autorelease]; NSArray *sortedCountries = [[countries sortedArrayUsingDescriptors:[NSArray arrayWithObject:descriptor]] retain]; } -(NSInteger)numberOfSectionsInTableView:(UITableView *)tableView { return 1; } -(NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section { return 2; } -(UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath { NSDictionary *country = [sortedCountries objectAtIndex:indexPath.row]; NSString *countryName = [country objectForKey:@"name"]; static NSString *CellIdentifier = @"Cell"; UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier]; if (cell == nil) { cell = [[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier] autorelease]; } cell.textLabel.text = countryName; return cell; } - (void)didReceiveMemoryWarning { [super didReceiveMemoryWarning]; } - (void)viewDidUnload { // Release any retained subviews of the main view. // e.g. self.myOutlet = nil; } - (void)dealloc { [sortedCountries release]; [super dealloc]; } @end </code></pre> <p><strong>EDIT:</strong> Another question related to this <a href="https://stackoverflow.com/questions/4879691/instance-variable-not-retaining-value-in-ios-application">here</a>.</p>

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.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
