Displaying NSMutableArray in a UITableView

I've made a UITableView in my ViewController. In this table view I want to add my data from NSMutableArray, but it does not seem to add the data. Any ideas?

This is the code I'm using.

- (void)viewDidLoad
{
    scoreArray = [[NSMutableArray alloc] init];

    NSDictionary *myVehicle = [[NSDictionary alloc] initWithObjectsAndKeys:@"Escape", @"name", @"SUV", @"type", nil];
    [scoreArray addObject:myVehicle];

    [super viewDidLoad];
}

- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {    

   static NSString *CellIdentifier = @"Cell";
   UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier forIndexPath:indexPath];

    if (cell == nil) {
        cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier];
    }

    cell.accessoryType = UITableViewCellAccessoryDisclosureIndicator;
    cell.textLabel.text = [[scoreArray objectAtIndex:indexPath.row] objectForKey:@"name"];
    cell.detailTextLabel.text = [[scoreArray objectAtIndex:indexPath.row] objectForKey:@"type"];

    return cell;
}

Based on your code you should be able to see one row. But here with no details, the problem is quite difficult to be identified.

Anyway, verify the following:

  • Does the datasource (and delegate) is set? This is done via XIB or by code?
  • Did you implement - (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section correctly?

Sample

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

The method - (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView should be implemented if you need a number of sections greater than 1. By default returns one.

In addition, I would modify a little bit the viewDidLoad method like the following.

- (void)viewDidLoad
{
    [super viewDidLoad]; // call it before any further initialization

    scoreArray = [[NSMutableArray alloc] init];

    NSDictionary *myVehicle = [[NSDictionary alloc] initWithObjectsAndKeys:@"Escape", @"name", @"SUV", @"type", nil];
    [scoreArray addObject:myVehicle];
}

Make sure your .h file indicates that this is the delegate for the UITableView: 

@interface ViewController : UIViewController <UITableViewDataSource, UITableViewDelegate>

Also make sure you implement the required datasource methods. In addition to what you have, you must have these:

- (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView {
    return 1;
}

and

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