Why does my UITableView only show two rows of each section?

Question

I have a UITableView and when I build it only two rows will be displayed. Each section has more than two cells to be displayed, I am confused since they are all done the same?

#import #import "Store.h"
#import "VideoViewController.h"

@implementation Store
@synthesize listData;

// Implement viewDidLoad to do additional setup after loading the view, typically from a nib.
- (void)viewDidLoad {
    [self createTableData];
    [super viewDidLoad];
}

- (void)didReceiveMemoryWarning {
    // Releases the view if it doesn't have a superview.
    [super didReceiveMemoryWarning];

    // Release any cached data, images, etc that aren't in use.
}

- (void)viewDidUnload {
    //self.listData = nil;
    //[super viewDidUnload];
    // Release any retained subviews of the main view.
    // e.g. self.myOutlet = nil;
}

    UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:StoreTableIdentifier];
    if (cell == nil) {
        cell = [[[UITableViewCell alloc]
                 initWithStyle:UITableViewCellStyleDefault
                 reuseIdentifier:StoreTableIdentifier] autorelease];
    }

    cell.textLabel.text = [[[listData objectAtIndex:indexPath.section] objectAtIndex:indexPath.row]
                                   objectForKey:@"name"];

            //Change font and color of tableView
    cell.accessoryType = UITableViewCellAccessoryDisclosureIndicator;
    cell.textLabel.font=[UIFont fontWithName:@"Georgia" size:16.0];
    cell.textLabel.textColor = [UIColor brownColor];
    return cell;
}

Answer 1

Replace this:

- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section { 
    return [self.listData count]; 
}

with:

- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section { 
    return [[self.listData objectAtIndex:section] count]; 
}

Answer 2

It looks like you're using only one value for the number of rows per section:

- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section { 
    return [self.listData count]; 
}

Does each section have the same number of rows? If not, you should be using section to grab the right number.

It's what's returned in this method (in your case, [self.listData count] ) that determines how many rows to display for that section.

I'd analyze the code some more but it's pretty hard to read... :)
