Question

In a single UiView controller class i’ve added 3 UITableView.

UITableView *ChaptersTableView;

UITableView *SubChaptersTableView;

UITableView *SubTopics1TableView;

Now in ViewDidLoad of class i’ve initialized these TableView’s & calling the Delegate & Datasource methods on these Table View’s.

ChaptersTableView = [[UITableView alloc]initWithFrame:CGRectMake(0, 0, 300, 300)];
ChaptersTableView.delegate=self;
ChaptersTableView.dataSource=self;

SubChaptersTableView = [[UITableView alloc]initWithFrame:CGRectMake(0, 0, 300, 300)];
SubChaptersTableView.delegate=self;
SubChaptersTableView.dataSource=self;



SubTopics1TableView = [[UITableView alloc]initWithFrame:CGRectMake(0, 0, 300, 300)];
SubTopics1TableView.delegate=self;
SubTopics1TableView.dataSource=self;

I wish to have different content & height for rows of different Table views. For eg. TableView1 will have cell height of 20, TableView2 will have cell height of 40 & TableView3 will have cell height of 60.

So how do i go about customizing these delegate & datasource methods depending on the tableView they are called for?

Thanks.

Answer 1

The delegate methods return the tableview object. Hence while creating you can tag the tableviews like this. SubTopics1TableView.tag = 0, SubChaptersTableView.tag = 1 etc.

In your delegate methods check the tag and configure the tableviews.
For eg

- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
{
if(tableview.tag == 0)
// Customise this tableview
}

To change how the cell will look you can use the delegate method:

-(void)tableView:(UITableView *)tableView willDisplayCell:(UITableViewCell *)cell forRowAtIndexPath:(NSIndexPath *)indexPath

To change the height of the row you can use:

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