Question

I know this is an oft-asked question/problem. I’ve looked through a bunch of Q&A for my problem, but I guess I’m a little thick, because I didn’t see an answer anywhere.

I have a file with in an array that I would like to use to populate a tableView.

The problem is that it’s not being called. Neither is numberOfRowsInSection or numberOfSectionsInTableView. I far as I can see, only viewDidLoad was called.

I have 1 section, the number of elements in my array equals 3 (as opposed to nil).

Relevant code is here…

- (void)viewDidLoad {   
    [super viewDidLoad];
    FileControl *fileArray = [[FileControl alloc] init];
    matArray = [fileArray findUniqueItemsInArray:0 :[fileArray setFileToArray]];
    [fileArray release];
    NSLog(@"%i \n %@", [matArray count], matArray); // matArray is filled.
    NSLog(@"ViewDidLoad"); }

- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {
    static NSString *CellIdentifier = @"Cell";

    UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
    if (cell == nil) {
        cell = [[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier] autorelease];
    }
    NSLog(@"CellForRowAtIndexPath");

    NSString *text = [matArray objectAtIndex:[indexPath row]];
    [[cell textLabel] setText:text];

    return cell; }

@interface MaterialTableViewController : UITableViewController <UITableViewDelegate, UITableViewDataSource> {

    IBOutlet UITableView *materialTableView;
    NSArray *matArray;

}

@property (nonatomic, retain) NSArray *matArray;

@end

The other methods are standard.

I guess my problem lies in that I don’t completely understand the flow well enough.

Any help would be greatly appreciated. Thanks in advance.

Have you set your UIViewController subclass to be the delegate and dataSource of the UITableView in question? Without doing so, none of the methods you mention will be called.
