    <p>I created a UITableView programmatically (not using a XIB). It reads a *.plist file containing an NSMutableArray of NSDictionary objects. The problem I am experiencing is this: When I display the objects in the UITableView, it never shows the object at row zero. I know this because I get the following NSLog output:</p> <pre><code>2009-06-01 10:02:34.566 Color[784:20b] array count = 4 2009-06-01 10:02:34.570 Color[784:20b] row = 3: Air 2009-06-01 10:02:34.570 Color[784:20b] row = 2: Earth 2009-06-01 10:02:34.571 Color[784:20b] row = 1: Water 2009-06-01 10:02:34.571 Color[784:20b] row = 0: Fire </code></pre> <p>What I will see, in this case, is a table with Water, Earth, and Air (but no Fire). If I add another object, then Fire will appear but the new object will not. Therefore, it is <em>always</em> the object at row 0.</p> <p>Here is some relevant code:</p> <pre><code>@interface LoadViewController : UITableViewController &lt;UITableViewDelegate, UITableViewDataSource&gt; { NSMutableArray *loadedObjects; } - (void)viewWillAppear:(BOOL)animated { self.loadedObjects = [self getCurrentData]; NSLog(@"array count = %d", [self.loadedObjects count]); [self.tableView reloadData]; [super viewWillAppear:animated]; } -(NSInteger)tableView:(UITableView*)tableView numberOfRowsInSection:(NSInteger)section { return [self.loadedColors count]; } -(UITableViewCell*)tableView:(UITableView*)tableView cellForRowAtIndexPath:(NSIndexPath*)indexPath { static NSString *Identifier = @"Identifier"; UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:Identifier]; if(cell == nil) { cell = [[[UITableViewCell alloc] initWithFrame:CGRectZero reuseIdentifier:Identifier] autorelease]; cell.showsReorderControl = YES; } NSUInteger row = [indexPath row]; NSDictionary *obj = [self.loadedObjects objectAtIndex:row]; cell.text = [obj objectForKey:@"Name"]; NSLog(@"row = %d: %@", row, [obj objectForKey:@"Name"]); return cell; } </code></pre> <p>In the code snippets you can also see my output to NSLog.</p> <p>When I had populated UITableViews from a NIB I had never experienced this problem. Any suggestions are appreciated.</p> <p>Thank you in advance.</p>

    1. COShould we assume that the separate loadedObjects and loadedColors are a typo here?

    2. COExcept for that typo, this seems good code. I'd start by switching out the cell.text assignment for something static, or something like "Cell %d". That way you can isolate the UITableView part from the loadedObjects and see which is the problem.

    3. COMaybe add a breakpoint on cellForRowAtIndexPath and verify your 'loadedObjects' property still contains what you're expecting it to contain?

Guidance
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.
