UITableView delegate methods

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

Accepted Answer

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];

}
```
