Can you run me through the steps to push an array to a UITableview?

Do this:

@interface SomeInstance : UITableViewController {
    NSArray *theArray;
}

@end

@implementation SomeInstance


- (void)viewDidLoad {
    theArray = [[NSArray alloc] initWithObjects:@"Apple",@"Pineapple",@"Banana",nil];
    [super viewDidLoad];
}


- (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView {
    // Return the number of sections.
    return 1;
}


- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section {
    // Return the number of rows in the section.
    return [theArray count];
}



- (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];
    }

    cell.textLabel.text = [theArray objectAtIndex:indexPath.row];    
    return cell;
}

- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath {
    UIAlertView *alert = [[UIAlertView alloc] initWithTitle:@"Selected a row" message:[theArray objectAtIndex:indexPath.row] delegate:nil cancelButtonTitle:@"OK" otherButtonTitles:nil];
    [alert show];
    [alert release];
}


- (void)dealloc {
    [theArray release];
    [super dealloc];
}


@end


If you're new to ObjC, I would suggest starting with something more simple before diving into UITableViews.

(sorry if that's not what you want to hear, but I figure you'll be more productive in the long run).

To answer your specific question, A class that inherits from UITableViewControllerDelegate is expected to support various methods required by the UITableViewController protocol.
