Question

I need a UITableView delegate method that need to be called from another function at compilation time…is there any default UITableView delegate methods that i can use? if not, please comment on how to add an extra delegate method in addition to the existing ones.

Thanks in advance

Make sure you set UITableview Delegate in either way – from NIB or programatially

Using NIB
From Nib :-

Programatically :-

then:-

-(void)viewWillAppear:(BOOL)animated
{
         tblService.delegate=self;
         tblService.dataSource=self;
         [super viewWillAppear:YES];
}

Use following delegates:

- (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView
{
    return 1;    //count of section
}


- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section {

    return [catagorry count];    //count number of row from counting array hear cataGorry is An Array
}



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

        UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:MyIdentifier];

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

        // Here we use the provided setImageWithURL: method to load the web image
        // Ensure you use a placeholder image otherwise cells will be initialized with no image
        [cell.imageView setImageWithURL:[NSURL URLWithString:@"http://example.com/image.jpg"]
                       placeholderImage:[UIImage imageNamed:@"placeholder"]];
            cell.textLabel.text = @"My Text";
        return cell;
    }

Below use for set height of cell

- (CGFloat)tableView:(UITableView *)tableView heightForRowAtIndexPath:(NSIndexPath *)indexPath
{

        return 80;

}

Below use for gatting particular cells data by selecting row this method called

- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath{

        Yourstring=[catagorry objectAtIndex:indexPath.row];      

       //Pushing next view 
        cntrSecondViewController *cntrinnerService = [[cntrSecondViewController alloc] initWithNibName:@"cntrSecondViewController" bundle:nil];
        [self.navigationController pushViewController:cntrinnerService animated:YES];

}
