Question

I have an NSMutableArray in with data (hard coded).

I implemented these two TableView methods and in IB, I’ve set the delegate and datasource

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

- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
    UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:@"UITableViewCell"];

    if (!cell) {
        cell = [[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:@"UITableViewCell"] autorelease];
    }

    cell.textLabel.text = [myArray objectAtIndex:[indexPath row]];
    NSLog(@"Cell is %@", [myArray objectAtIndex:indexPath.row]);
    return cell;
}

The data won’t appear in the TableView. I’ve ran NSLog and I can see the data is in myArray.

I added the NSLog to the code and it appears the code never executes. The question is how is my array being created?

Here’s the code

- (id)init:(NSMutableArray *)theArray
{
    [super init];
    countryTable.delegate = self;
    countryTable.dataSource = self;

    UITapGestureRecognizer * tapRecognizer = [[[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(viewTapped:)] autorelease];
    [window addGestureRecognizer:tapRecognizer];

    myArray = [[NSMutableArray alloc] init]; 
    myArray = theArray;
    return self;
}

Your basic code is correct, just need to have an array (which you haven’t provided here), so this would be one example:

NSMutableArray *myArray = [NSMutableArray arrayWithObjects:@"One",@"Two",@"Three",nil];

And you can NSLog this: NSLog(@"Count: %i, Array: %@",[myArray count], myArray);

Output: Which should return as the cell.textLabel.text per your example

Count: 3, Array: (
“One”,
“Two”,
“Three”
)

You should also make sure that you set the UITableViewDelegate and UITableViewDataSource protocols in your header.
