Working with multiple data-sources in UITableView

Using this post, I am going to explain “working with multiple data-sources in UITableView”.

Expected Output of this tutorial is demonstrated by following images.

Step 1 : load data into your arrays ( if you are fetching from xml/web do that, I have implemented static here )

- (void)viewDidLoad
{
    [super viewDidLoad];
    self.arOne=[NSArray arrayWithObjects:@"Sagar",@"Amit",@"Nimit",@"Paresh",@"Rakesh",@"Yogesh", nil];
    self.arTwo=[NSArray arrayWithObjects:@"Supreeth",@"Deepthy",@"Ankit",@"Sandeep",@"Gomathy", nil];
    [self.tableView reloadData];
}

Step 2 : Implement coding in such a way that handles multiple data-sources. It means place conditional coding as following example

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


    UITableViewCell *cell = [self.tableView dequeueReusableCellWithIdentifier:CellIdentifier];
    if (cell == nil) {
        cell = [[[UITableViewCell alloc]  initWithStyle:UITableViewCellStyleDefault  reuseIdentifier:CellIdentifier]  autorelease];
    }


    cell.textLabel.text=[(self.btnTapped.selected)?self.arTwo:self.arOne objectAtIndex:indexPath.row];


    return cell;
}

Step 3 : Add a connection to your button or whatever control that you are using.


- (IBAction)btnTitle:(id)sender {
    self.btnTapped.selected  =  !self.btnTapped.selected;
    [self.tableView reloadData];
}
