UITableView delegate methods
Solution 1
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];
}

I don't know if this method exist but if you need other methods in a UITableView
delegate you can Create a new Category of UITableViewDelegate
